Humic Acid Fertilizer

Source and Composition

Humic acid fertilizer comes from things like leonardite, peat, or old plants and animals. It has special molecules called humic substances. These form as plants and animals break down over time. When you use humic acid, you add carbon, hydrogen, oxygen, and other small elements to the soil. These things help crops and seedling grow well. They make the soil better and help it hold water.

How It Works

Humic acid changes how soil acts. When you add it, soil enzymes work harder. Enzymes like urease and sucrase break down old plant stuff. This gives nutrients to your plant. The soil gets more good fungi and bacteria. Bad ones go down. This helps crops and seedling take in more nutrients and grow strong.

Humic acid can also lower soil pH. This helps some crops and seedling get nutrients easier. The soil cycles nutrients better and stays healthy.

• Humic acid fertilizer:

  • Makes soil enzymes work better for nutrients.

  • Helps good microbes and lowers bad ones.

  • Makes soil stronger and richer.

  • Helps crops and seedling take in nutrients well.

Plant Growth Benefits

Humic acid fertilizer helps plants start strong. Seedling grow bigger roots and thicker stems. Crops grow better and give more food. Humic acid helps plants fight stress from dry weather or bad soil. Leaves look greener, flowers bloom more, and fruit is better. Humic acid makes nutrients easier to use and keeps soil healthy. If you want strong crops and seedling, humic acid fertilizer is a good, natural choice.

Seaweed Extract Fertilizer

Source and Composition

You get seaweed extract from marine algae, mostly brown seaweed like kelp. People harvest seaweed from clean ocean waters. They process it to make a liquid or powder. Seaweed extract contains natural plant hormones, vitamins, amino acids, and minerals. You also find trace elements like iron, zinc, and magnesium. These nutrients help crops and other plants grow strong. Seaweed extract is an organic option for gardeners who want to avoid chemicals.

How It Works

Seaweed extract works by giving your plant a boost of natural compounds. These compounds help plants use nutrients better. Seaweed extract contains cytokinins, auxins, and gibberellins. These plant hormones control cell division and root development. When you apply seaweed extract, your plant grows faster and roots get stronger. The extract also helps crops handle stress from heat, drought, or salty soil. You can use seaweed extract as a foliar spray or add it to the soil.
