ABSTRACT
To meet the demand of food for increasing world population from limited land and water resources, a key issue in modern agriculture, could be achieved through adoption of conservation agriculture (CA). CA has the ability to achieve expected yield in the long run with the help of modification/restored of physical, chemical, and biological properties of soil. The role of soil in the soil-plant-atmosphere continuum is unique. The crops are grown in the soil, and soil properties directly or indirectly affect the availability of water and nutrients to crops. This review of literature provides an overview of the impact of CA on soil quality with particular emphasis on key soil physical, chemical and biological properties. The review of numerous studies indicated that soil quality and yield improvements are possiblein CA although some negative results have also been reported under contrasting environments. CA is particularly relevant to the areas which have high level of soil degradation, water scarcity and low soil fertility status.
Key words: Conservation agriculture, Soil properties, Crop yield, Zero tillage, Residues retention
