Temporal soil fertility with organic nitrogen sources in acidic soil of Meghalaya
نویسندگان
چکیده
A field experiment was conducted at CAU, Umiam, Meghalaya during kharif 2017 to investigate the effect of nitrogen application through urea and Azolla on temporal soil fertility build-up under low land rice cultivation 30, 60, 90 days after transplanting (DAT) maturity in acidic soil. The consists six treatments with without incorporation laid out RBD four replications. 60 kg N/ha along @16000 kg/ha (T6) recorded highest available N (289.98 kg/ha) harvest which significantly superior over control (227.45 kg/ ha) 9.1% increase. Similarly, this treatment P, K OC i.e. 20.6, 192.3, 2.1 followed by T5 T2. Further, it also observed that T6 were statistically significant T4 whereas T3 respect advancement crop age.

amounts involved are much smaller. The amount of boron in the 7-ton potato crop (if determined) would have been about 0.2 pound. In the case of boron (and to a lesser degree the other micronutrients) if the soil contains excessive amounts, toxic quantities are absorbed by plants and growth is restricted. The need for a reasonable balance in amounts of available nutrients in the soil has been po...
متن کاملSoil fertility and biodiversity in organic farming.
An understanding of agroecosystems is key to determining effective farming systems. Here we report results from a 21-year study of agronomic and ecological performance of biodynamic, bioorganic, and conventional farming systems in Central Europe. We found crop yields to be 20% lower in the organic systems, although input of fertilizer and energy was reduced by 34 to 53% and pesticide input by 9...
متن کاملManaging soil fertility in organic farming systems
12 Complex relationships exist between different components of the organic farm and 13 the quantity and quality of the end products depend on the functioning of the whole 14 system. As such, it is very difficult to isolate soil fertility from production and 15 environmental aspects of the system. Crop rotation is the central tool that integrates 16 the maintenance and development of soil fertil...
متن کاملThe Effect of Land use and Soil Erosion on Soil Organic Carbon and Nitrogen Stock
Soil organic carbon (SOC) is a principal component in soil quality assessment. Knowledge of SOC and total nitrogen (TN) stocks are important keys to understand the role of SOC in the global carbon cycle and, as a result, in the mitigation of global greenhouse effects. SOC and TN stocks are functions of the SOC concentration and the bulk density of the soil that are prone to changes, influe...
