Better Biostimulants

High-Test Ag humic acid and fulvic acid have been formed through microbial degradation of plants over thousands of years. Unlike “new carbon” peat or wood pulp, our products contain agronomically functional humified carbon that offers reliable benefits to both soil composition and plant growth. The best way to ensure you’re using the most beneficial Humic and Fulvic is to look for the High-Test Ag label.

Last year we used both Humic-HT and Fulvic-HT in-furrow and in various other applications. We saw improved early season vigor, as well as season-long plant health and standability. This translated into higher yields on those acres. We will be applying Humic-HT and Fulvic-HT again this year.
