Effect of Long Term Manuring on Soil Carbon Stock and Some Biological Properties under Rice – Rice C

This research was completed activity to determine the effect of various manurial treatments on the batch of carbon amounted to soil through stubble in rice-rice cutting system, basic carbon stock and allure relation to organic properties in an Inceptisol of Bhubaneswar, Odisha. This has happened contemplated in existent Long Term Fertilizer Experiment which is started since 1994 located in Central Research Station, OUAT accompanying Rice-Rice cropping series. The experiment dealt with six situations during the eighth crop phase viz, 100% NPK, 100% NPK + FYM, 100% N, 100% NP, 100% NPK +Lime, control (no produce) with 4 replications in a randomized block design. Both in the kharif and the rabi seasons, edible grain stubble accompanying undisturbed roots was carefully collected, treated, and tested for total element after edible grain harvest. The usual approach was trailed when collecting and resolving soil samples. Between 1223.5 and 2571.5 kg/ha of carbon and 2998.9 to 6330.85 kg/ha of total beard were absorbed into the soil. After kharif and rabi, the surface carbon stock of the soil categorized from 7.41 to 12.50 Mg/ha and 7.14 to 11.76 Mg/ha, respectively. After kharif, the SOC of surface soil categorized between 3.48 and 6.51 g/kg and 3.35 and 6.13 g/kg. In 100% NPK+ FYM, the maximal amounts of stubble, beard carbon, and MBC were raise. No manuring improved the BD (1.42 Mg/m3) but the addition of FYM and beard decreased the BD (1.28 Mg/m3). MBC different from 45.89 to 132.41 g of carbon per g of soil. The importance of subble adding in enhancing SOC was explained by the considerably positive partnership between SOC and portion of stubble adding (r = 0.85), carbon adding by stubble (r = 0.94), and carbon stock (r =0.91**). Similar to this, the MBC-SOC links (r = 0.83**), which backed the contribution of SOC to composite formation. The powerful positive link 'tween SOC and MBC suggests that adjoining carbon helps to enhance soil health, and rice hay is an excellent beginning of carbon. It needs expected suppressed in the soil.
