As a biostimulant, seaweed extract has been used as fertilizer for hundreds of years. Seaweed extract can effectively improve soil structure and provide rich nutrients for crop growth. The technology of using seaweed as the raw material of biostimulant extract has been used for many years. People are starting to develop and use other plants as the raw material of the extract as well.
Soil plays the most important role in the healthy growing of crops. Humic acid and fulvic acid are natural organic acids that exist naturally in soil. They come from the decomposition of plants, animals, and microorganisms, as well as soil microbial activity and substances like shale, coal, mudstone, etc.
