Building soil health, improving carbon footprint and minimizing greenhouse gas emissions through CSR.

Abstract

Unabated soil degradation due to low soil organic carbon (C) levels. multiple nutrient deficiencies including micro-and secondary nutrients. rising salinity and soil loos due to erosion jeopardizes food security of swlfUy risIng global population projected to be 9.7 billion by 2050. Soils also play a major role In global C cycling and huge C sequestration potential offers opportunities for mitigating carbon dioxide and other greenhouse gas emis:slons. The lessons learnt from CSR pilot and scaling-up Initiatives indicated significant productivity benefits with soil health rnapplng-based management. The linkages of soil health and food quality are documented. Soil mapping-based management Increased C sequeslI'ation with higher proportion of blomass C and enhanced uptake and use efficiency of nitrogen fertilizers. and thereby reducing losses through runoff and gaseous emissions. Management at watershed level Is proved as one o(the most lI"usted approach to managing natural resources and reducing runoff. 8Oil l088 and C and nutrients therein. Table 3.1. Ecosystem services provided by the soil, and soil foocIions that support these services.

Biochar‐based nutrient management as a futuristic scalable strategy for C‐sequestration in semiarid tropics

“…In the drylands, widespread soil carbon loss is a major problem and a continuing challenge in enhancing food production and realizing productivity potential (Chander et al., 2018; Gomiero & Gomiero, 2016; Shepherd et al., 2009; Usman et al., 2015). The soil carbon, cation‐exchange capacity, and pH further affect urea hydrolysis in soil, a major external source of nitrogen in cereals (Ohnemus et al., 2021).…”
