We do not recommend using any other source of so called humate
based on years of research testing products being sold as humates worldwide.
An example of the worst product for plant growth we ever tested came
from a company in W. China. The product was never used or tested in agriculture
even in China and the product is strictly for industrial use like in drilling
muds, flux, ceramics and other industrial uses. This product contains high
levels of humic acids but not bioactive functional groups known to be bioactive,
so don't be fooled! It may be cheaper but is what you see below worth paying
ANYTHING for?
The Cabbage plants from Left to right are treated with Russian Sodium/potassium
humate,Chinese Potassium humate, New Mexico based Potassium Humate (Humisolve-USA™).
The interesting part is only the Humisolve-USA treated cabbage resisted
both insect and slug damage. Insect and disease resistance is provided
by phenol groups not found in coal based humates and these humates carry
toxic organic compounds found in coal and oil. The New Mexico "Humate"
we use is not coal and is effective at stimulating plant growth in the
form it comes from the ground in and coal is not.
