Key soil parameters, organic matter, pH and plant nutrients determine the capacity of a to sustain animal productivity. Conservation agriculture (CA) crop diversification or intensification may change these parameters positively negatively, which eventually affect long-term sustainability. We monitored key properties (at depths 0–15 15–30 cm) under CA-based sustainable practices: zero-till (ZT), residue retention, rotations on Inceptisols Entisols in Eastern Ganga Alluvial Plains from 2014...
