What sets Menefee Humate apart?

1. The Source. Humics vary widely in quality. Our products originate from northwest New Mexico, the world's premium source for freshwater humates. Our products are free of harmful salts and toxins, and consistently test high in humic and fulvic acids.

2. Cleanliness. Unlike dusty humics, Menefee Humate® goes through a multiple-screened process. The finished product is uniform in particle size, which is easy to blend and apply. Want to try it out? Get in touch for a free sample.
