Labile soil carbon inputs mediate the soil microbial community composition and plant residue decomposition rates.
Root carbon (C) inputs may regulate decomposition rates in soil, and in this study we ask: how do labile C inputs regulate decomposition of plant residues, and soil microbial communities? In a 14 d laboratory incubation, we added C compounds often found in root exudates in seven different concentrations (0, 0.7, 1.4, 3.6, 7.2, 14.4 and 21.7 mg C g(-1) soil) to soils amended with and without (13...
متن کاملEffect of Incorporation of Crops Residue into Soil on Some Chemical Properties of Soil and Bioavailability of Copper in Soil
Objective: Returning crop residue to the soil exerts favorable effects on physical and chemical properties of soil. In fact, the plant residues can affect soil conditions such as pH and important role in soil fertility and cycling of elements in the soil may have. In addition to the role of the organic matter from decomposition of crop residue in increasing the concentration of micronutrients i...

متن کاملSuccession of bacterial populations during plant residue decomposition in rice field soil.
The incorporation of rice residues into paddy fields strongly enhances methane production and emissions. Although the decomposition processes of plant residues in rice field soil has been documented, the structure and dynamics of the microbial communities involved are poorly understood. The purpose of the present study was to determine the dynamics of short-chain fatty acids and the structure o...
متن کاملEffects of Residue Decomposition on Productivity and Soil Fertility in Rice–Wheat Rotation
containing about 1.90 million Mg of nutrients, are available in the IGP of India (Sarkar et al., 1999). In the Rice (Oryza sativa L.)–wheat (Triticum aestivum L.) farmers in Indian Punjab alone, about 12 million Mg of rice straw India burn or remove residues to facilitate seedbed preparation. Incorare burned annually, which causes about 0.7 million Mg poration of residues before planting of the...
