Replenishing Humic Acids in Agricultural Soils
Agronomy, 2016 For many decades, it was commonly believed that humic acids were formed in soils by the microbial conversion of plant lignins. However, an experiment to test whether these humic acids were formed prior to plant matter reaching the soil was never reported

Plant hormone crosstalk mediated by humic acids
Chemical and Biological Technologies in Agriculture, 2022 Background The reliance on chemical inputs to support high yields is the Achilles’ heel of modern crop production. The soil organic matter management is as old as agriculture itself. Recently, the use of soluble humic substances as plant growth promoters
