ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...
15 صفحه اولSuccession 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...
متن کاملEffects of foraging waterfowl in winter flooded rice fields on weed stress and residue decomposition
This study quantifies the agronomic benefits of foraging waterfowl in winter flooded rice fields in the Sacramento Valley of California (US). Fifteen winter flooded rice fields along a 105 km long transect, each with five pairs of waterfowl exclosures and control plots were used to measure residue decomposition in spring, and weed biomass and grain yield at harvest. Experimental exclusion of wa...
