Effect of residue retention on soil quality parameters under conservation agriculture in vertisols of central India

Abstract: Conservation Agriculture (CA) is an advance approach to achieve improved soil health and ecologically and economically sustainable agriculture. Residue management under CA restricts its adoption by the farmers resulting in in-situ burning of the crop residues. This burning of the residues pollutes the environment and also results in loss of essential plant nutrients, and adversely affects beneficial soil micro-flora and fauna. Therefore, a field study was conducted in an ongoing CA field experiment to evaluate the effect of residue management practices on soil quality parameters under maize (Zea mays L.) chickpea (Cicer arietinum L.) cropping system in Vertisols of central India. The experiment was conducted in randomized complete block design with six replications and four treatments comprising different residue retention levels. The results showed improved physical properties of soil viz. bulk density and porosity at 0-5 and 5-10 cm depth with residue retention under CA. The maximum soil organic carbon (1.01%) was recorded with 90% residue which was followed by 60% and 30% residue retention level. Therefore, by following the CA-based residue management practices can help in improved soil quality along with the advantage of higher and sustained crop productivity.
