Carbon sequestration and carbon stock inventory under different land use systems of Semi-Arid region of Bundelkhand of Uttar Pradesh

Abstract

Abstract The study was conducted in different land use systems in Badokhar Khurd block Banda district Bundelkhand region of Uttar Pradesh. The experiment was laid out randomized block design using seven land use systems four soil layers (L) and each different land use system replicated thrice. The results have revealed that different land use system have significant influence on the production of above ground biomass, belowground biomass and total biomass, which affect the carbon stock and CO2 mitigation potential the maximum aboveground biomass carbon stock (8.30 t ha-1), belowground biomass carbon stock (2.16 t ha-1) and total biomass carbon stock (10.46 t ha-1) was exhibited by (SPS). While minimum above ground biomass carbon stock (0.51 t ha-1), belowground carbon stock (0.13 t ha-1) and total biomass carbon stock (0.65 t ha-1) was found in (NGS). Maximum bulk density was recorded in agriculture crop-based land-use (1.45g cm-3) followed by (ASS) and (AHS) while minimum bulk density was recorded in (SPS) (1.36g cm-3). Maximum soil organic carbon stock was recorded in (SPS) (4.97 t ha-1) followed by (HPS), while minimum soil organic carbon stock agriculture crop-based land-use (2.63 t ha-1). As a result, the maximum total carbon stock was recorded (SPS) (29.35 t ha-1) followed by (HPS), (ASS), (AHS) and agriculture crop-based land use while minimum total carbon stock was recorded in (NGS) (11.87 t ha-1).
