Soil Dynamics for Carbon Buildup in Different Land Use Systems in the South Region of Gujarat, India

Abstract

Soil dynamics for carbon build-up vary across different land use systems. Understanding the soil dynamics and land use system management practices that contribute to carbon build-up is essential for designing effective carbon sequestration strategies. In a recent study, fifteen different land use systems were examined, including agriculture land-use systems, tree plantation land-use systems, and agroforestry land-use systems. The study assessed the potential of these land use systems to store carbon based on the extent of tree components. Various physical and chemical characteristics of the soil and their impact on soil carbon conservation were also investigated. The results showed that as the number of tree components increased, the soil pH and bulk density decreased from 6.10 to 5.55, and 1.48 to 1.33g/cm3. The available soil nitrogen was significantly higher in tree plantation land-use systems than in agriculture land use systems while soil moisture was higher in the latter. Tree components increase soil carbon build-up and agroforestry land use systems fulfill the requirement for human and environmental balance.
