Managing Crop Residue for Soil Health Improvement in India

Dibyendu Sarkar, Siddhartha Mukherjee, G. Pratibha, Sumanta Kundu

This chapter discusses various crop residue management issues, including strategies, effects, and challenges for soil health improvement in India. Crop residue retention is an energy-saving and environmental conservation practice. Conservation agriculture, which has been emphasized as a key route to sustainable intensification, …

Arid Eco‐Region and Dryland Soil Health

Sumanta Kundu, Ch Srinivasarao, V. K. Singh, Jami Naveen

This chapter presents some technological solutions and policy measures to holistically address soil and nutrient-related constraints in arid and semi-arid drylands in India. Drought reduced the percentage of nitrogen and phosphorus, suggesting that it hindered nutrient uptake rather than growth. Land degradation …

Evaluating the Effects of Fertilizer Deep Placement on Greenhouse Gas Emissions and Nutrient Use Efficiency in Wet Direct-Seeded Rice During the Wet Season in Assam, India

Jami Naveen, Khagen Kurmi, Mrinal Saikia, Kalyan Pathak et autres

Mitigation of greenhouse gases (GHGs), improving nutrient-use efficiency (NUE), and maximizing yield in rainfed lowland rice cultivation poses significant challenges. To address this, a two-year field experiment (2020 and 2021) was conducted in Assam, India, to examine the impact of different fertilizer-management …
