soil-enzymes
Soil enzymes are biological catalysts produced by soil microorganisms—including bacteria, fungi, and archaea—that drive the decomposition of organic matter into humus while releasing essential nutrients. They are central to nutrient cycling in plant ecosystems, determining how efficiently elements like nitrogen and phosphorus become bioavailable for root uptake. Understanding and managing soil enzyme activity is therefore key to optimizing soil fertility and sustainable plant growth.

Pesticides routinely used on crops can disrupt the soil microbes that keep farmland healthy, but the extent of damage and recovery depends heavily on soil conditions, chemical type, and land management history. This review calls for better monitoring of soil enzyme activity as an early-warning system for pesticide harm.
Pesticides and their breakdown products can both inhibit and stimulate soil microbial communities depending on soil chemistry, contamination history, and management practices — there is no single universal response.
Key soil enzymes (dehydrogenases, ureases, and phosphatases) are sensitive indicators of pesticide disturbance, but their usefulness as recovery markers is limited and context-dependent.
Long-term microbial resilience and recovery after pesticide exposure remain poorly understood, highlighting a critical gap in current soil health science.
