Crop residues management option for sustainable soil health in rice-wheat system: A review


Author(s): Neelam Bisen and CP Rahangdale

Abstract: Rice-wheat system is a dominating cropping system of India and sustainability of it is at risk due to the deterioration of soil health and challenges of climate change. High yields of the irrigated Rice-wheat system have resulted in production of huge quantities of crop residues. Burning of rice straw is common in north-west India causing nutrient losses and serious air pollutions affecting human health. To avoid straw burning, innovations in crop residue management should assist in achieving sustainable productivity and allow farmers to reduce nutrient and water inputs, and reduce risk due to climate change. Crop residues contain significant quantities of plant nutrients and their judicious application will have positive effect on nutrient management in rice wheat system. Long-term studies of the residue recycling have indicated improvements in physical, chemical and biological health of soil. Other plausible option of crop residues management lies in utilizing a portion of surplus residue for producing biochar as soil amendment to improve soil health, increase nutrient use efficiency and minimize air pollution and other i.e. mushroom cultivation as converting of inedible crop residues into valuable food, surface mulch as conservation of soil moisture and weed problem, biofuel and compost production. Residue decomposition in soil substantially increases the soil organic carbon and other nutrient. In this review authors have discussed residue potential and possible options for with efficient management of crop residues in the rice wheat cropping system.
