humic acid

Question

Does anyone know how to make your own humic acid?

Answer 1

Humic acid is found in compost, peat moss, and other organic materials, and in soil. The best way to add it is to make compost tea or to add more organic matter to soil. It is not necessary to extract humic acid from these materials before adding them to soil.
