ABSTRACT
Optimum soil physical health is very important for efficient utilization of nutrients in any crop production system. Conservation agriculture (CA) is beneficial to soil physical improvement as compared to conventional tillage. Conservation practices can neutralize these negative effects of soil compaction as minimum tillage or zero tillage and residues can modify soil ecosystem along with crop rotations. Crop rotation contributes to the development of soil structure, by returning of crop residues, developing and better distributing biopores and positively affecting dynamics of microbial communities. Soil bulk density is an indicator of soil compaction and expressed as the weight of the dry soil in a given volume. The interaction of tillage and crop rotation also proved to be established significant to soil porosity. As soil physical environment imparts direct and indirect effects on soil chemical as well as biological environments significantly, the adoption of systematic CA is a great way out towards sustainability of soil health in the long run.
