humic and fulvic acid can be using to improve farm yields

October 21, 2022

Research conducted on farms across our test field has shown a positive yield benefit from using humic acid . The results were even more conclusive when targeting lower organic matter or eroded soils and/or fields that were under drought stress. Although drought stress increased the chance of getting a yield response, the greatest yield response was observed in XinJiang a Irrigated field where a 65% increase in yield was noted.

Noteworthy is that most of these organic fertilizer applications were applied at the same time as a pesticide, primarily herbicide, was being applied. This results in less application cost since the pesticide was a planned application. However, benefits of humic and fulvic acids are usually greatest when applied with plant nutrients. It is my opinion an even higher confidence of response could be realized if applying these products with nutrient applications.

Responses have also been observed in soybeans where humic acid has been applied. In 2013, pod counts have increased as much as 23%.

In Conclusion, Humic and Fulvic Acids are tools farmers should be using to improve yields across their farms.

Some ways to assure consistent responses are:

Apply specifically to lower organic matter soils or eroded soils.

Apply in lighter textured, more droughty soils.

Use in high pH soils where nutrient tie-up is greater, especially where iron deficiency is a concern.

Apply in soils where there are other restrictions such as sodium (>2% sodium base saturation) or aluminum toxicity (pH<5.3).

Apply Fulvic acid especially with foliar nutrition or with in-row fertility to enhance nutrient uptake.

Apply Humic Acid with nitrogen fertilizers to reduce the losses and enhance the response and efficiency of the nitrogen.

Using Humic Acid and Fulvic Acid can reduce the variability in yield that a farmer experiences across his fields due to differences in soils. Call us at KHUMIC if you are interested in trying "FulvicPlus" Fulvic Acid or "KHUMIC 100" Humic Acid on your farm this year.
