    Sodium Humate Basics

    What Is Sodium Humate

    Sodium humate is a natural substance that comes from humic acid. Humic acid forms when plants and animals break down in soil and coal. People make sodium humate by using different methods like physical, chemical, and biological fermentation. This makes a product with lots of carbon, hydrogen, and oxygen. It also has a little nitrogen and sulfur. The molecules have special rings and groups, such as aromatic rings and sulphuric acid groups. There are also nitrogen rings like pyrrole. These parts give sodium humate its special features.

    Note: Sodium humate looks like a dark powder or small grains. When you put it in water, the water turns a soy sauce color. This color helps block sunlight and stops algae from growing.

    How It Works

    Sodium humate works with water at the tiny molecule level. It has active groups like carboxylic, phenolic, and hydroxyl. These groups break apart in water and make the molecules charged. The charges help sodium humate swap ions and grab onto metals. The molecules open up and become more active. This helps them stick to toxins and heavy metals in the water. This action lowers bad things in the water and makes it cleaner.

    Sodium humate also helps water molecules line up in an organized way. This makes the water thicker and helps nutrients move better. When the pH is neutral, sodium humate makes networks that help keep water healthy for fish and plants. These things make sodium humate useful for taking care of pond and tank water.

    Aquaculture Applications

    People use sodium humate in aquaculture for many reasons:

    1. Water Quality Improvement: Sodium humate grabs onto calcium, magnesium, and heavy metals. It also sticks to toxins and other bad things, making water safer.

    2. Detoxification: It makes a thin layer on the intestines of fish and shrimp. This stops toxins from getting in. It also soaks up protein toxins and heavy metals.

    3. Substrate Improvement: Sodium humate has tiny holes that loosen pond dirt. It soaks up ammonia and hydrogen sulfide, which cuts down on bad smells.

    4. Shading: By coloring the water, sodium humate blocks sunlight and keeps algae from growing too much.

    5. Plant Growth: It helps enzymes work and makes aquatic plants grow better.

    6. Feed Additive: Sodium humate keeps the gut bacteria healthy and helps the immune system in fish and shrimp.
