Effect of long-term application of organic residues on the distribution of organic matter and nitrogen in some rice soil profiles

Soil carbon budget in a single-cropping paddy field with rice straw application and water management based on soil redox potential

“…Thickness of the topsoil depended on the machinery plowed depth not on straw management. There have been several reports showing an increase in soil carbon content by successive application of rice straw on a decadal time scale using non volcanic‐ash soils in Japan (Gotoh et al. 1984; Shirai et al.…”

Effect of Organic Inputs on Strength and Stability of Soil Aggregates Associated Organic Carbon Concentration under Rice-Wheat Rotation in Indo-Gangetic Plain Zone of India

“…In China, Liu and Weng (1991) found that returning rice straw to rice fields for 2 years usually increased soil organic matter content by 0.03 to 0.05%. From a longterm field experiment in Japan, Gotoh et al, (1984) estimated that 13 to 25% of the organic matter returned to soil through rice straw was incorporated into the soil organic matter in a slowly permeable grey lowland soil. In a long-term study on a rice-wheat cropping system in northwestern India, the incorporation of crop residues along with green manure in rice increased soil organic carbon and total N contents as compared to straw removal, but the increase was almost similar to that when crop residues were applied alone.…”

Bacterial Communities Responsible for the Decomposition of Rice Straw Compost in a Japanese Rice Paddy Field Estimated by DGGE Analysis of Amplified 16S rDNA and 16S rRNA Fragments

“…The application of rice straw compost to paddy fields has been investigated extensively in terms of its effects on soil nitrogen fertility, soil organic matter content and growth of rice (e.g. Maeda and Shiga 1978;Gotoh et al 1984Gotoh et al , 1986Inoko 1984;Shiota et al 1984;Shiga et al 1985a, b). Its effects on soil microorganisms have also been well documented.…”
