Humic acid (HA) is a macromolecular organic substance that is widely used in agriculture, forestry, animal husbandry, chemical industry, building materials, medicine, environmental protection, and a ...

Humic substances (HSs) constitute a broad group of heterogeneous organic macromolecules that originate from the decomposition of plant and microbial residues in soils, sediments, and aquatic systems 1 ...

Soil organic matter is often described as the foundation of soil fertility. It helps soils hold nutrients, retain water, support microbial life, and store carbon. Yet scientists are still working to ...

A major compound in soil organic matter degrades chronic wasting disease prions and decreases infectivity in mice, according to a new study. A major compound in soil organic matter degrades chronic ...

This study used Density Functional Theory (DFT) at the B3LYP/6-31G(d, p) level to develop a model for humic acid (HA), characterizing it as an organic molecule with functional groups featuring ...

A reader e-mailed me with a question about humic acid. Since the quality of their lawn is not as good as they desire it to be, a lawn service has recommended an application of humic acid. They want to ...
