Sodium humate is a type of humic acid salt that is commonly used in agriculture, animal feed, and environmental applications. Here are some examples of how sodium humate can be applied:

1. Agriculture: Sodium humate can be applied to soil to improve its fertility and increase crop yield. It can also improve the absorption of nutrients by plants, making them healthier and more resistant to diseases.
2. Animal feed: Sodium humate can be added to animal feed to improve digestion and nutrient absorption, as well as to promote growth and overall health.
3. Environmental applications: Sodium humate can be used to remediate contaminated soil and water by binding to heavy metals and other pollutants, preventing them from being absorbed by plants or animals. It can also be used as a drilling fluid additive in the oil and gas industry to reduce fluid loss and stabilize wellbore walls.
4. Other applications: Sodium humate has also been used in the production of ceramics, as a flocculant in wastewater treatment, and as a binder in the manufacture of fertilizer pellets.

It is important to note that the specific application and dosage of sodium humate will depend on the intended use and the characteristics of the soil or water being treated. It is always recommended to consult with a professional before applying sodium humate to ensure proper usage and effectiveness.
