| Summary, etc. |
Labile soil organic matter pools are the early indicators of soil carbon sequestration by any management practice.|Hence, dynamics of dissolved organic matter and microbial biomass was studied during crop growth period at monthly interval under conservation agriculture in the second year of rice-wheat cropping sequence in a calciorthent (free CaCO3, 33%). Soil respiration (SR) was also studied at one month interval during wheat growth period. The plots were under no till (NT) or conventional till (CT) management with residues retained (+) or removed (-). Under conventional tillage, plots in rice (puddled), transplanted, dry-seeded broadcasted and wet pre-germinated seeded were considered. Under conservation tillage plots, dry direct seeding was done on flat as well as beds. Sesbania was grown in half of each plot, which was killed after 30 days of sowing by 2-4 D (brown manuring). There was a little variation in organic carbon C of the different plots. In rice-wheat cropping system, NT (+) plots (in each crop) improved mean DOC concentration by 64.2 and 78.0% and the mean MBC concentration by 25.4 and 32.5% in rice and wheat crops, espectively, in comparision to CT (-) plots (in each crop). NT (+) plots, in spite of having higher organic matter in the form of crop residues, had 12% lower mean SR than CT (+) plots. In the two treatments, grain yields of rice were at par|but grain yield of wheat was significantly higher in CT (+) (in each crop). MBC concentration increased and DOC concentration decreased with increasing growth period of both the crops. Brown manuring maintained higher mean DOC as well as mean MBC concentration in the treatments. Higher concentrations of DOC and MBC and lower soil respiration in the NT (+) plots may help in higher organic C restoration than the CT (-) plots in the calciorthent. |
