Key Points

Compare the individual and combined impacts of chemical herbicides, mineral fertilizers, and mechanical tillage on soil ecosystem integrity.
Evaluated agricultural management practices including mechanical soil disturbance versus chemical weed termination.
Assessed relative impacts of cover crop termination strategies on overall soil physical structure and biology.
Mechanical tillage induces significant physical disruption to soil layers compared to chemical cover crop termination.
Direct comparison highlights trade-offs between synthetic inputs and physical disturbance on long-term soil health.
