Global climate change is anticipated to have a tremendous influence on crop productivity and nutrient cycling in legume-based cropping systems. The effect of long-term application of manure and fertilizers on the dynamics of soil organic carbon (SOC) pools and soil physical properties was studied in a soybean (Glycine max Merr. L)–wheat (Triticum aestivum L.) system. The temperature sensitivity of C pools and the alterations in microbial composition were determined at 25, 35, and 45 ◦C. Higher levels of microbial biomass C (MBC) and nitrogen (MBN), water soluble carbon (WSC), acid hydrolysable carbohydrates (AHC), particulate organic matter carbon (POMC) and nitrogen (POMN) were observed in the NPK + FYM at a depth of 0–15 cm. Irrespective of the treatment, micro aggregates (53–250 m) were a major aggregate size class, comprising 45–57% of the total soil aggregates, followed by macro aggregates (250–2000 m at 37.8–45%). Microbial respiration rate increased by 13.9% in most recalcitrant pools ( Not Available |
