Humic acid benefits and usage in Australia
Humic acid gives many benefits for farming and gardening in Australia. Farmers and gardeners use humic acid to make soil healthier. It helps the soil hold more water. It also helps plants grow better, even in tough Australian soils and weather. More people are using it across the country:
ProdOz International made a fertiliser called Fertica H+ with humic acid. Trials in Western Australia and Tasmania showed healthier soil and less need for synthetic fertiliser.
Broadacre farmers used 17% more humic acid in 2023. They want better soil structure and water holding.
Government agencies now use humic acid to help fix mine sites. This means it is used for more than just farming.

Humic acid overview
What is humic acid
Humic acid is a natural part of soil, peat, and coal. It is found in the dark part of soil. Scientists say humic acid is made of big molecules. These molecules have lots of oxygen-rich groups like carbonyl, carboxyl, and hydroxyl. The structure also has nitrogen and sulphur. About half of humic acid is carbon. The rest is mostly oxygen, hydrogen, and nitrogen. Aromatic rings are a big part of its structure. This helps humic acid stay strong in soil. These groups let humic acid join with metals and nutrients. This makes it easier for plants to get them. Because of this special structure, humic acid helps soil and plants.
How it forms
Humic acid forms when plant and animal remains break down in soil. Microbes in the soil help with this job. They break down leaves, roots, and other things. As they do this, new and bigger molecules are made. These become humic acid. Many things affect this process, like water, air, sunlight, and soil pH. Soils with more air often have more humic acid. This is because oxygen helps microbes work faster. The kind of plants and how water moves in soil also matter. Over time, the organic matter changes and grows. This leads to more humic acid in healthy soils.
Types of humic substances
Soil scientists put humic substances into three main groups: humic acid, fulvic acid, and humin.
Humic acid can dissolve in water if the soil is neutral or alkaline. It does not dissolve in strong acids. It has big molecules with lots of carbon, oxygen, hydrogen, nitrogen, and sulphur. Humic acid helps soil keep nutrients and water. It also helps microbes and makes soil better.
Fulvic acid can dissolve in water at any pH. It has smaller molecules than humic acid. It can move into plant tissues easily. Fulvic acid helps plants take in nutrients and deal with dry times.
Humin does not dissolve in water at any pH. It has the biggest molecules and is very strong. Humin makes soil better and helps it hold water. It also keeps nutrients for a long time.
Note: Humic substances are grouped by how they dissolve in water and their chemical make-up. Each type helps soil and plants in its own way.
Australian context
Australia has special problems with its soil and weather. Many places have sandy, salty, or acidic soil. These soils make it tough for plants to grow well. Farmers and gardeners want to make soil better and get more crops. Humic acid and humate are now used a lot in Australia.
Humic acid helps soil in many ways. It helps soil keep water, which is important in dry places. Soils in Western Australia and South Australia lose water fast. Humic acid slows down water loss. Plants have more time to take in water. Humate also makes soil stick together. This stops soil from washing or blowing away in storms.
Lots of farmers use humic acid to make soil better. They mix it with fertiliser or put it straight on fields. Humate comes as granules or liquid. Farmers pick the type that fits their crops and soil. Wheat farmers in New South Wales mix humic acid with nitrogen fertiliser. This helps stop nitrogen from washing away in sandy soil.
Tip: Humic acid works best with organic matter. Farmers often use compost or manure with humate.
Fruit and vegetable growers in Victoria and Queensland use humic acid too. It helps roots grow strong. Strong roots help plants get food and fight stress. Humate wakes up good microbes in the soil. These microbes break down organic matter and give food to plants.
Mining companies use humic acid to fix land. Mine sites often have poor soil with little food for plants. Humic acid helps soil get better and helps plants grow. Government groups say humate is good for planting new plants on old mine land.
Region | Soil Challenge | Humic Acid Benefit | Common Application |
|---|---|---|---|
Western Australia | Sandy, dry soils | Water retention | Liquid humic acid with fertiliser |
Queensland | Acidic soils | pH balance, root growth | Humate granules in horticulture |
Tasmania | Low organic matter | Microbial stimulation | Humic acid in compost |
Australian scientists keep testing humic acid and humate. They try new products and check results in different weather. Many tests show more crops and better soil. Farmers, gardeners, and land managers think humic acid is important for farming in Australia.
Humic acid in Australian agriculture
Soil fertility
Australian farmers have problems with their soil. The soil often has little organic matter and is not strong. Humic acid helps make the soil better and richer. When farmers use humic acid or humate, the soil sticks together more. This makes small clumps in the soil. Roots can move through these clumps and find food. Humic acid also adds more carbon to the soil. More carbon helps the soil stay healthy. It also gives food to good microbes.
Studies in Australia show humic acid helps soil fertility. It makes the soil structure better and gives more nutrients. Farmers see their crops grow stronger and healthier with humic acid. Humus 100 is a powder that many farmers use. It helps the soil hold water and stops disease. These things help crops live in hard Australian conditions.
Note: Humic acid works best with compost or manure. This mix gives the soil more food and helps plants grow.
Nutrient efficiency
Many soils in Australia lose nutrients fast. Nitrogen is lost quickly. Humic acid helps keep nutrients in the soil. Plants can use them for longer. It holds onto nutrients and stops them from washing away. This is important for sandy soils in Western Australia and South Australia.
Farmers mix humic acid with fertilisers. This helps the soil keep nutrients and makes fertilisers work better. Fulvic Acid Liquid is another product used in Australia. It helps plants take up nutrients faster. It also makes fertilisers work better. Farmers use it with many liquid fertilisers like NPK and trace elements. It works well for sprays, irrigation, and hydroponics.
Humic acid and fulvic acid help plants get more nutrients.
They stop nutrients from getting stuck in the soil.
These acids help seeds sprout faster and roots grow deeper.
Australian studies show humic acid helps nitrogen work better. It stops nitrogen from washing away or turning into gas. Farmers can use less fertiliser and still get good crops. The soil stays healthy and crops grow well.
Water retention
Water is very important in Australia. Many places have dry soil that loses water fast. Humic acid helps the soil hold more water. It acts like a sponge and keeps water near the roots. This is called water retention and aeration. When the soil holds water, plants can live through dry times.
Farmers use humic acid to help the soil keep water. Humus 100 helps the soil hold moisture and fight drought. Humic acid also helps the soil get more air. Roots get more oxygen and plants grow strong.
Product | Application Method | Benefit for Water Retention |
|---|---|---|
Humus 100 | Soil amendment | Holds more water, reduces drought stress |
Fulvic Acid Liquid | Foliar spray, irrigation | Helps plants take up nutrients, helps during dry spells |
Australian farmers use humic acid as a solid or liquid. They use 5 kg/ha to 1 t/ha for solids. For liquids, they use 1–50 L/ha. These ways are common, but there are no set rules. Farmers should follow product advice and local tips for best results.
Tip: Using humic acid with fertilisers and compost gives the best water retention and healthy crops.
Microbial activity
Soil stays healthy because of living things inside it. Farmers in Australia use humic acid and humate to help good microbes grow. These substances wake up bacteria and fungi. Microbes break down organic matter. This gives plants the nutrients they need.
Humic acid makes the soil better for microbes. It gives them food and helps them move around. Humate also helps soil stick together. This lets air and water reach the microbes. More microbes means more types and more activity in the soil.
Australian farmers get many benefits from using humic acid and humate:
Crop leftovers break down faster
Plants get more nutrients
Roots grow stronger
There is less disease in the soil
Product | Microbial Benefit | Common Use in Australia |
|---|---|---|
Humic acid | Helps bacteria grow | Mixed with fertiliser for crops |
Humate granules | Boosts fungi and bacteria | Spread on big fields |
Farmers often use humic acid with compost or manure. This gives microbes extra food and energy. Many farmers use liquid humic acid in irrigation or as a soil soak. Humate granules are good for big fields like wheat and barley.
Tip: Using humic acid and humate often keeps soil life busy and helps plants grow strong.
Soil health
Structure improvement
Soil needs to have a good structure to be healthy. When soil structure gets better, plants can grow strong roots. They can also take in water and nutrients more easily. In Australia, many soils are sandy or packed down. These soils break apart or do not keep water well. Farmers and gardeners use humic acid and humate to help with these issues.
Humic acid works like glue in the soil. It sticks small bits of soil together to make bigger clumps called aggregates. These clumps make spaces for air and water. Roots can move through the soil more easily. Water stays in the soil longer, so plants do not dry out fast.
Tests in Victoria show humic acids act like cement in soil. When farmers used potassium humate, the soil kept 10% more water. This extra water helps keep nitrogen close to the roots. Plants can use this nitrogen to grow better. Long-term tests show mixing organic manure with humic substances makes more big clumps. These bigger clumps hold more organic carbon. More carbon means the soil is better and has more nutrients.
Tip: Farmers in Australia often use humic acid with compost or manure. This mix gives the best results for making soil structure better.
Good soil structure helps stop soil from washing away. It also lets good microbes live and work in the soil. When soil has strong clumps, it can help crops grow well every year.
Detoxification
Australian soils sometimes have bad chemicals like heavy metals and pesticides. These can hurt plants and lower crop amounts. They can also be dangerous for people and animals. Farmers and gardeners want safe ways to clean their soil. Humic acid and humate are natural choices for detoxification.
Humic acid works like a magnet for toxins. Its big molecules have many places to grab onto harmful things. These places can stick to heavy metals like lead, cadmium, and mercury. When humic acid grabs these metals, it makes strong bonds. Plants cannot take in these bonds easily. This keeps bad substances away from plant roots.
Humate helps clean soil too. It traps pesticides and other bad chemicals. Humate’s structure lets it hold onto these toxins. Over time, soil microbes break down the trapped chemicals. This makes soil safer for crops. It also lowers the chance of pollution getting into food.
Note: Humic acid and humate do not take toxins out of soil. They lock them up and make them less dangerous. This is called immobilisation.
Australian farmers use humic acid and humate in different ways to clean soil:
They put humic acid granules on fields with lots of chemicals.
They mix liquid humic acid into water for vegetable crops.
They add humate to compost to help break down pesticides.
Toxin Type | How Humic Acid Helps | Common Australian Practice |
|---|---|---|
Heavy metals | Binds metals, reduces uptake | Granular humate in broadacre cropping |
Pesticides | Traps chemicals, aids breakdown | Liquid humic acid in horticulture |
Salt | Buffers sodium, protects roots | Humate with gypsum for saline soils |
Humic acid and humate help with salty soils too. They buffer sodium and protect roots from salt. Many places in Australia have problems with salty soil. Farmers in Western Australia and South Australia use humate with gypsum to help soil.
Using humic acid and humate often makes the environment cleaner and safer. These substances help Australian growers control soil pollution without strong chemicals. They also help keep farming sustainable by making soil healthy for the future.
Using humic acid and humate for detoxification is a smart way to get safer food and a healthier land in Australia.
Plant growth benefits
Root development
Strong roots are important for healthy plants. In Australia, dry and hard soils make it hard for roots to grow. Humic acid and humate help roots grow deeper and stronger. They make the soil better for roots to move and find water.
Researchers found humic acids from vermicompost help roots grow bigger and better. Worm castings with humic and fulvic acids help soil life and give more food to roots. Australian tests show humic acid helps soil keep up to 25% more nutrients. It also helps soil hold 10% more water. These changes help roots and plants grow better.
Humic acid from vermicompost works better than other products for roots and fruit.
Humate helps more microbes grow, so roots get more food.
Wheat tests in Australia show better roots and more crops with humic acid, even in dry or salty soil.
Tip: Strong roots help plants live through tough Australian weather and give more crops.
Nutrient uptake
Plants need to take in nutrients to grow well. Humic acid and humate act like sponges in soil. They hold water and nutrients for plants. This helps fertilisers work better and gives plants more food.
Humate makes roots bigger, so plants can take in more nutrients. Australian products from Leonardite help soil and make it easier for roots to get food. Experts say to use humic acid as part of a good plant food plan. They also say to test soil and leaves often to know what each crop needs.
Humic acid helps roots get more nutrients.
Humate works well with other plant boosters to help plants grow.
Using good humic acid the right way is important for best results.
Note: When plants take in more nutrients, they grow better and give more crops.
Stress resistance
Australian crops often face dry weather, salty soil, and hot or cold days. Humic acid and humate help plants handle stress better. They help soil keep water and support strong roots. This lets plants live through dry or salty times.
Tests in Australia show humic acid helps crops grow 5-10% more under stress. Plants with strong roots and good food can get better after bad weather. Humate also helps good microbes, which protect plants from disease and stress.
Humic acid helps wheat and other crops handle stress.
Humate helps plants keep growing in hard seasons.
Better stress resistance means farmers get more crops, even in tough times.
Using humic acid and humate often helps plants stay healthy and grow well, even when Australian weather is hard.
Crop yield
Australian farmers want to get more crops each year. Humic acid and humate help them do this. These natural substances help plants grow and make soil better. When soil keeps more water and nutrients, crops grow stronger. This leads to better yield.
Humic acid makes wheat have more grains. It also helps fruit get bigger in orchards. Farmers in Victoria and Queensland get more crops after using humic acid with fertiliser. Humate helps crops use nutrients well. This means plants can make more food with less fertiliser.
Farmers often see 10–15% more crops when they use humic acid and humate.
The table below shows how humic acid and humate help different crops:
Crop Type | Humic Acid/Humate Benefit | Yield Improvement (%) | Common Practice in Australia |
|---|---|---|---|
Wheat | Better root growth, water retention | 12% | Liquid humic acid with nitrogen |
Tomatoes | Nutrient uptake, stress resistance | 15% | Humate granules in soil beds |
Grapes | Soil structure, microbial activity | 10% | Humic acid in drip irrigation |
Barley | Detoxification, pH balance | 13% | Humate with compost |
Farmers use humic acid and humate in different ways. Some mix liquid humic acid with water for irrigation. Others put humate granules on the soil before planting. These methods help crops get more water and nutrients. This makes yield go up.
Tests in Australia show humic acid works well in sandy and acidic soils. These soils lose nutrients quickly. Humic acid keeps nutrients close to the roots. This helps plants grow and gives more crops. Humate helps soil microbes. Good microbes break down organic matter and give food to plants. This helps crops grow and improves yield.
Humic acid helps crops get better after dry weather.
Humate helps roots grow strong.
Both substances make soil better for plants.
Farmers in Western Australia use humic acid to get more wheat and barley. Fruit growers in Tasmania add humate to compost for more apples and berries. These ways show humic acid and humate are important for getting more crops in Australia.
Using humic acid and humate is a smart way to get more crops and healthier plants.
Humic and fulvic acids
Differences and similarities
Scientists look at humic and fulvic acids to see how they help soil. Both are part of humic substances, but they have different chemical features. Humic acids have bigger molecules, but new studies show their average size can be smaller because they stick together. Fulvic acid can make bigger clumps in some situations. The size of both acids changes with pH, how much is present, and the strength of ions.
The table below shows how they are different and alike:
Aspect | Humic Acids | Fulvic Acids | Similarities/Notes |
|---|---|---|---|
Molecular Size | Usually thought to be bigger, but some studies show smaller average sizes because of how they clump together | Can make bigger clumps in some conditions | Both have changing sizes that depend on things like pH, amount, and ion strength |
Charge and Colloidal Stability | More negative charge means they stay mixed better | Stay mixed better as pH goes up because of group changes | Both clump together and change size; charge affects how they move in the environment |
Functional Groups | More phenolic groups; fewer carboxylic groups | More carboxylic groups; fewer phenolic groups | The types of groups change how they bind protons and act as acids or bases |
Aggregation Behaviour | Clumps can be many sizes; stable structures can form | Clumps together more easily, making bigger particles at medium amounts | Clumping depends on the environment; both make changing structures |
Acid-Base Properties | Fewer carboxylic groups compared to phenolic; different constants for protonation | More carboxylic groups; changes how they act as acids and bases | Both have acid and base properties that matter for how they work in soil |
Environmental Influence | Size and clumping change a lot with pH, ion strength, and amount | Same changes happen; clumping and size shift too | Both are main parts of soil organic matter and have complex, changing structures |
Studies show fulvic acid has more carboxylic groups and less phenolic groups than humic acid. The ratio of phenolic to carboxylic groups is lower in fulvic acid. These differences change how each acid binds protons and works with soil minerals. Both acids are important for soil organic matter, but fulvic acid is a special chemical type.
Combined effects
Australian farmers use humic and fulvic acids together to help plants grow. These acids grab onto nutrients like iron, zinc, and manganese, making them easier for plants to use. They make soil crumbly, which helps roots grow and water move. Humic and fulvic acids also help soil keep water, which is good for roots in dry or sandy places.
Farmers see many good things when they use these acids:
Plants take up more nutrients from the soil.
Soil gets more air, so roots spread out.
Soil holds more water, helping crops in dry times.
Good microbes become more active and help cycle nutrients.
Fulvic acid helps roots and shoots grow and helps seeds sprout.
Plants handle drought, salty soil, and tough pH better.
Both acids help clean soil by grabbing heavy metals.
Plants make more food and grow stronger.
Plant defences get better, so crops fight off diseases and pests.
Tests in Victoria show potassium humate, a kind of humic acid, makes soil clumps stronger. This helps explain how humic and fulvic acids work together to help Australian soils.
Phosphorus availability
Phosphorus is needed for plants, but many Australian soils do not keep it well. Humic and fulvic acids help phosphorus move by holding different types of organic phosphorus. These acids have phosphate monoesters, diesters, phosphonates, sugar-diester phosphates, pyrophosphates, polyphosphates, and inorganic orthophosphate. Organic phosphorus is the biggest part of the phosphorus that can be taken from soil, and humic acids make up most of it.
The chart below shows how much of each phosphorus type is in humic and fulvic acids:
Humic and fulvic acids store phosphorus and slowly give it to plants. This helps keep nutrients balanced and lets crops grow well. Farmers in Australia use humate and humic acid products to help plants get more phosphorus, especially in soils that do not have much.
Usage and application
Granular application
Granular humic acid and humate help make soil better in Australia. Farmers and gardeners use granules for big fields, lawns, and gardens. Granules are good for large spaces because they spread easily. They break down slowly and give nutrients over time.
How much you use depends on your soil and crops. Sandy soils need more granules to keep water and nutrients. For most lawns and gardens, use 5–10 kg for every 100 square metres. Big farms use 50–200 kg for each hectare, mostly before planting. You can mix granules with compost or fertiliser to make them work better.
Application Area | Typical Rate | Best Practice |
|---|---|---|
Lawns | 5–10 kg/100 m² | Spread evenly before rain or watering |
Garden beds | 5–10 kg/100 m² | Mix into topsoil or compost |
Broadacre fields | 50–200 kg/ha | Apply before sowing or with fertiliser |
Tip: Put granular humic acid or humate down before rain or watering. Water helps granules break up and reach roots.
Granular products are good for Australian soils that need slow help. They help sandy and acidic soils keep water and nutrients longer.
Liquid application
Liquid humic acid and humate work fast for soil and plants. Gardeners and farmers use liquids for quick nutrients and better root growth. Liquids are good for spraying on leaves, soaking soil, and watering systems.
Here are some best ways to use liquid humic acid:
Use humic acid as a soil soak before flowers grow. This makes roots stronger and helps plants.
Always follow the label for mixing rates. Mixing right keeps plants safe and helps humic acid work.
Do not mix humic acid with strong copper or sulphur sprays. These can hurt good soil life.
Keep soil wet and airy after using humic acid. This helps good microbes and makes humic acid work better.
Change biological products during the season. This helps different microbes and gives better results.
Mix humic acid with things like mycorrhizae or seaweed. These mixes help plants take in food and fight stress.
Check soil pH (best is 6.0–7.0) and organic matter. Change how you use humic acid to fit your soil.
Application Method | Dilution Rate | Timing | Notes |
|---|---|---|---|
Soil drench | 1:100–1:500 | Before flowering | Strengthens roots |
Foliar spray | 1:200–1:500 | Early growth stages | Avoid strong fungicides |
Irrigation | 1–50 L/ha | Throughout season | Combine with biostimulants |
Note: Always read product labels and ask for local advice. Liquid humic acid works well for vegetables, fruit trees, and big crops.
Liquid humic acid is good for places that need quick help. It helps plants get better after stress and grow in tough Australian weather.
Timing and frequency
When and how often you use humic acid matters a lot. Farmers and gardeners in Australia plan when to use it based on crops, soil, and weather.
Use granular humic acid before planting or sowing. This gives soil time to take in nutrients and get better.
Use liquid humic acid at important times, like before flowers or when roots start growing.
Use humic acid every 4–6 weeks for lawns and gardens. Big fields may need it 2–3 times each season, depending on rain and crops.
Use it more often in dry or sandy soils. This helps keep water and nutrients in the soil.
Check soil health often. Soil tests help you change when and how much you use.
Application Type | Best Timing | Frequency | Target Area |
|---|---|---|---|
Granular | Pre-planting, autumn | 1–2 times per season | Lawns, gardens, fields |
Liquid | Early growth, pre-flowering | Every 4–6 weeks | Vegetables, fruit, crops |
Tip: Using humic acid and humate often keeps soil healthy and helps plants grow strong all year.
Australian growers see better soil, more water held, and healthier crops when they use humic acid at the right times.
Compatibility
Compatibility is very important when using humic acid and humate with other fertilisers in Australia. Farmers and gardeners want to mix these products the right way. This helps plants grow well and keeps soil healthy. Using the best combinations gives better crops and good soil.
Humic acid and humate can be used with many fertilisers. NPK fertilisers give plants nitrogen, phosphorus, and potassium. These often mix safely with humic acid. This mix helps plants take in more nutrients and makes soil better. But there are some things to remember to avoid problems:
Always mix humic acid with water before adding NPK fertiliser. This helps the mix go into the soil and reach roots.
Use the right amount of humic acid. Too much can upset the balance of nutrients.
Watch for plant stress or signs that plants are missing nutrients after using it. Using too much can cause issues.
If you are not sure, test a small amount first. This helps you see if there are any bad reactions.
Using the right amount and mixing carefully gives the best results and keeps risks low.
Fertiliser Type | Compatibility with Humic Acid/Humate | Best Practice |
|---|---|---|
NPK | High | Dilute humic acid before mixing |
Urea | Good | Mix with water, avoid overuse |
Phosphate-based | Good | Monitor for nutrient lock-up |
Trace elements | Variable | Test small amounts before full use |
Tip: Humic acid and humate can help fertilisers work better. Always read the label and ask local experts for advice in Australia.
Some fertilisers with lots of copper or sulphur do not mix well with humic acid. These can hurt good microbes in the soil or stop humate from working. Do not mix humic acid with strong fungicides or pesticides unless the label says it is safe.
In Australia, it is best to check soil health before and after using humic acid and humate. Regular soil tests help farmers change their fertiliser plans if needed. This keeps the soil balanced and helps plants grow strong.
By following these steps, farmers and gardeners can use humic acid and humate safely with most fertilisers. This helps crops grow well, keeps soil healthy, and gives better results on Australian farms and gardens.
Animal and human health
Animal feed
Farmers in Australia now add humic acid and humate to animal feed. These natural substances can help animals grow and stay healthy. Studies in Australia and other countries show humic acid helps animals in many ways. The table below shows some main results:
Evidence Aspect | Description |
|---|---|
Broiler Chicken Studies | Humic acid makes meat better, changes fats, helps growth, boosts immunity, and keeps tissues healthy. |
Ruminant Research (Australia) | University of Sydney found humic substances change rumen microbes and help with nitrogen use. |
Antimicrobial, Antioxidant, Immunomodulating Properties | Humic substances help animals fight sickness and stay healthy. |
Australian Product Availability | Local companies make humic supplements, showing support for animal feed use. |
Farmers see that animals eating humic acid often have better meat and stronger immune systems. In ruminants, humic acid changes the microbes in the stomach. This helps with digestion and how the animal uses nitrogen. Tests using rumen simulation show humic substances do not hurt fermentation or lower feed quality. They can even lower ammonia and help good microbes grow. This makes humic acid and humate good choices for better livestock in Australia.
Human supplements
Humic acid and humate are now used as supplements for people. Some people think these substances can help the immune system and fight viruses. Early studies show humic acid might stick to viral proteins and help the immune system. But most research is still in labs or on animals. Reviews of products like Shilajit, which has humic acid and fulvic acid, show some safety and health benefits. But these reviews often look at fulvic acid or the whole product, not just humic acid.
There are not many clinical trials on humic acid for people. Old safety studies give some information, but they do not tell us about long-term use or the right amount. WebMD and other sources say there is not enough good information about humic acid’s safety or side effects in people. The quality of supplements can change a lot, so experts say to be careful until more research is done.
Note: People should talk to a doctor before using humic acid or humate supplements, especially if they are pregnant, breastfeeding, or have health problems.
Safety
Safety is very important for animals and people using humic acid and humate. In animal feed, studies in Australia and other places show these substances do not hurt digestion or lower feed quality. They can even make animal products better by helping health and growth. For people, safety is less clear. Most studies are early and there are not many clinical trials. The quality of humic acid supplements can be different between brands, and some may not be cleaned well.
Experts say people should only use high-quality, well-tested products. They should not use supplements with unknown ingredients or unclear sources. Until more research is done, it is best to use humic acid and humate carefully and follow advice from professionals.
Humic acid and humate help make soil healthier in Australia. They also help crops grow more and make animal feed better. Farmers see that soil holds water longer and keeps nutrients better. Gardeners find their plants are stronger and their fruit and vegetables are better. Using humic acid the right way gives the best results and keeps soil good.
Looking after land for a long time means using humic acid to keep soil and animals healthy.
