Research Progress of Humic Acid Fertilizer on the Soil

Abstract

Humic acid fertilizers are currently widely used in agricultural production, soil remediation and environmental protection. The application of humic acid fertilizer in the soil can not only optimize the soil structure and increase the utilization rate of fertilizers, but also promote the growth of crops, thereby achieving the effect of increasing yield and income. In the repair of contaminated soil, humic acid fertilizers can fix heavy metals and degrade organic pollutants. Based on this, in order to promote the efficient application of humic acid fertilizers in soil, the application of humic acid fertilizers in soil improvement and remediation of contaminated soil was explored.
