carbon and nitrogen mineralization in a calcareous soil amended with plant residues and sulfur
carbon (c) and organic nitrogen (n) mineralization processes play key roles in supplying nutrient elements essential for plant growth. on the other hand, since the low organic matter content of agricultural soils of arid and semi-arid areas, microbial activities are often limited by carbon in these types of soils. enhancement of microbial activities and populations could be achieved by returnin...
متن کاملAssessing changes in soil microbial communities and carbon mineralization in Bt and non-Bt corn residue-amended soils
The effects of Bt corn (Zea mays L.) residue on soil microbial communities and rates of C mineralization were investigated. The Bt corn residue had a higher lignin content (12%) and lignin/N (9.9) ratio compared with its non-Bt near-isoline (10% lignin; lignin/N = 8.6). We examined the relationships among the Bt/non-Bt residue properties, residue component, soil texture, sampling time, and till...
متن کاملthe decomposability of some plant residues and their susbsequent influence on soil microbial respiration and biomass, and enzyme activity
abstract soil microbial activity and biochemical processes are often limited by carbon availability in arid- and semi-arid regions, probably due to the low organic matter content. consequently, return of plant residues to soil is a convenient and effortless practice for increasing microbial activities and biochemical reactions. the primary objective of this study was to evaluate the effect of v...
متن کاملInfluence of Herbicide Triasulfuron on Soil Microbial Community in an Unamended Soil and a Soil Amended with Organic Residues
The effect of organic amendments and pesticides on a soil microbial community has garnered considerable interest due to the involvement of microorganisms in numerous soil conservation and maintenance reactions. The aim of this work was to assess the influence on a soil microbial community of the simultaneous application of the herbicide triasulfuron at three doses (2, 10, and 50 mg kg-1), with ...
