How do researchers define humic acid compared to other soil amendments?

Answer 1

Researchers define humic acid as a biologically active organic material distinct from compost, biochar, or synthetic fertilizers. Unlike basic soil amendments, humic acid works at a molecular level to improve nutrient exchange, stimulate beneficial microbes, and enhance root absorption. This makes it far more effective in boosting soil chemistry and plant physiology. JINGFENG HUMIC ACID develops products backed by research that demonstrates these unique advantages. When researchers define humic acid, they emphasize its ability to bind micronutrients, buffer soil pH, and improve water retention—features not commonly found in other soil conditioners. As a result, humic acid is widely adopted in agriculture, horticulture, and turf management. Understanding how experts define humic acid helps users differentiate it from other inputs and select the right solutions for maintaining healthy, productive soils.
