Used in agricultural and environmental research to measure phosphatase enzyme activity in soil, this ELISA kit helps assess soil fertility and microbial activity. It enables scientists to evaluate how effectively organic phosphorus is being converted into available forms for plants. The test is useful in monitoring soil health, optimizing fertilizer use, and studying the impact of land management practices such as crop rotation, tillage, and organic amendments. It is also applied in ecological studies to compare enzyme activity across different ecosystems or under varying pollution levels.
