Used in environmental and agricultural research to quantify acid phosphatase enzyme activity in soil samples. This measurement helps assess soil health and microbial activity, as acid phosphatase plays a key role in organic phosphorus mineralization. The kit enables researchers to evaluate phosphorus availability in different soil types, monitor changes due to land use, and study the impact of fertilizers or pollutants on soil enzyme function. It is also applied in ecological studies to compare soil biological activity across ecosystems or under various management practices.
