Soil carbon depletion is a major concern for food security in drylands. The objective of this study is to test tillage with residue management under sequential and intercropping systems for carbon sequestration in semi-arid tropical drylands of India. We report the findings from a long-term field experiment (9 years) used to simulate the effect of residue and tillage management in Maize-chickpea sequential and Maize-Pigeonpea intercropping systems for the four possible future climate projections using APSIM model.

Soil salinization is a significant form of land degradation in agricultural areas. Remote sensing is a better way to assess soil salinity than traditional methods, as it provides non-destructive and repetitive informative assessment for monitoring and mapping soil salinity. Different sensors can identify soil salinity in remote sensing data through direct and indirect indicators. A Brief review of the major soil salinity mapping studies is presented here.
