Carbon Dynamics in Climate Smart Agriculture Precision Land Leveling Practices on Topsoil Microbial Community Changes and Soil Organic Carbon in Cereal Based Cropping Systems of Sub-Tropical India: A Review

Abstract

The role of soil microorganisms in the biogeochemical process and nutrient cycling of soil is critical and is colossally impacted by agronomic management practices. In order to establish climate-smart precision land leveling practices in cereal based cropping systems, comprehension of the land bacterial local area and supplement nutrient dynamics under differentiating management practices is of most extreme significance. Climate smart agriculture (CSA) practices are gaining traction in subtropical India as a viable alternative to conventional cereal-based cropping systems for reversing natural resource depletion. Sustainable soil management alternatives that sequester carbon in the soil, reduce greenhouse gas (GHG) emissions and help intensify production, all while enhancing the natural resource base. Aggregate-associated soil organic carbon (SOC) contents in 0-15 cm depth were recorded highest SOC at 15-30 cm depth in Precision Land Leveling (PLL) systems as 9.4% for both M-P-MbPLL and M-W-MbPLL. Highest PON change in arable cropping system (30.9 & 40.1%) was found in O-W-Mb with precision land levelling plots followed by R-P-O with precision land levelling plots (26.1 & 35.8%) as compared to R-W and S-W system. The values of LFOC in surface soil were 194.7, 187.9, 176.2, 170.9, 168.5, 150.6, 132.8 and 123.8 mgkg−1 in R-P-O, R-C-O, M-W-Mb, O-W-Mb, M-P-Mb, R-P-Mb, R-W and S-W with precision land leveling treatments. Therefore, adopting Climate Smart Agriculture Precision Land leveling practices can dramatically boost system productivity in cereal-based cropping systems by improving SOC and soil biological quality. The overview literature accrued indicate that CSA based totally totally management has a remarkable impact on top soil resilience in phrases of relative abundances of bacterial groups, soil organic carbon & to be had plant nutrients and as a result may additionally play a vital function within the sustainability of the extensive cereal based cropping systems.
