Loss of fertilizer efficiency through volatilization, immobilization, and leaching is extremely costly not only to farmers but also to our environment. Traditional N-P-K fertilizer can become tied up within days and can easily be lost in low…

Multi-site, multi-year study of humic products by USDA researchers Dan Olk and Dana Dinnes finds a clear financial benefit for corn and soybean farmers with applications of humic products.
In our seventh No-Till Farmer podcast, brought to you by Montag Manufacturing, we welcome Richard Mulvaney to talk about why nitrogen fertilizers are not building your soils, and what you can do about it.
When it comes to mitigating the worst impacts of climate change, keeping excess carbon out of the atmosphere is the prime target for improving the health of our planet. One of the best ways to do that…
Adding carbon to the soil is critical to restoring health to the soil by increasing the organic matter content. Producers in today’s modern agricultural systems are working with soils that contain far less carbon than our soils…
It is well known that raw humates are refractory, which means it has been fixed by acidic radicals (hydrogen bonds) and this form is nonionized. In order to make raw humate ionized, we use KOH to replace…
Primary Macronutrients: The primary nutrients are nitrogen, phosphorus and potassium. You may be most familiar with these three nutrients because they are required in larger quantities than other nutrients. These three elements form the basis of the…

In this lecture, Dr. Mir Seyedbagheri, who is an agronomist with the Elmore County extension through the University of Idaho, spoke at the 2013 Sustainable Agriculture Symposium about soil health. His scientific lecture talks about Wet Chemistry…
One of the main reasons for the differences in soil carbon between organic and conventional systems is that synthetic nitrogen fertilizers degrade soil carbon. Research shows a direct link between the application of synthetic nitrogenous fertilizers and…
Based on research, humic substances are formed as follows: Lignin Modification Quinone Acid Interactions Microbial Synthesis of Aromatics Sugar Amino Acid Reaction Sequences However, it takes thousands of years of these reactions, coupled with lignin dissolution, to…
At this point, no scientists have been able to provide a descriptive and definitive molecular picture of humic substances. They are polydispersed polyanions and are supermixtures of many different acids containing carboxylate and phenolate groups and others,…
