Frequently Asked Questions
What crop types benefit from an application of Humic DG granules?
All crops, including broadacre crops, trees and soft fruits, vegetables, vine crops, and nursery/greenhouse soils, benefit from Humic DG granules. Research has shown average yield increases of 5-10 bushels per acre of corn and 2-7 bushels per acre of soybeans.
When, and at what rate, should Humic DG granules be applied?
Humic DG granules can be applied whenever nutrients are applied, or with specific growth stages of the crop. Application rates vary from 5 to 40 pounds per acre (see reverse for specific rates). A program approach is most effective.
How does the humic acid content of Humic DG granules compare to other liquid and dry humic acid products?
As a granular soil amendment with 70% humic acid (A&L method), Humic DG granules compare favorably to dry, granular, and powdered humic acid products. Humic acid is more effective in the soil than most of the competitive products due to the self-incorporating microparticles that provide greater surface area for soil activity and contain all three humic fractions.
Can Humic DG be considered for organic or sustainable agriculture?
Yes, Humic DG is a great fit for organic and sustainable agriculture. It is OMRI Listed and OIM Certified in California.
How does humic acid affect nitrogen volatilization?
The high reactivity of humic acid retains the nitrogen in the ammonium form, preventing it from volatilizing to ammonia and not being utilized by the plant.
Do humic acids influence phosphorus activity in the soil?
Yes, increased phosphorus availability has been observed in academic studies. Humic acid impacts both short-term and long-term phosphorus availability.
