متن کاملSoil Aggregate Size Affects Phosphorus Desorption from Highly Weathered Soils and Plant Growth
Wiersum, 1962; Cornforth, 1968; Misra et al., 1988), but freshly applied P may penetrate only a thin layer Because plant absorption of P depends on the desorption of P around soil aggregates (Gunary et al., 1964; Linquist et from soil, understanding P desorption from soils may improve the precision of P diagnosis and fertilization recommendations. Many al., 1997), suggesting that larger soil ag...
متن کاملAn environmental threshold for degree of phosphorus saturation in sandy soils.
There is critical need for a practical indicator to assess the potential for phosphorus (P) movement from a given site to surface waters, either via surface runoff or subsurface drainage. The degree of phosphorus saturation (DPS), which relates a measure of P already adsorbed by a soil to its P adsorption capacity, could be a good indicator of that soil's P release capability. Our primary objec...

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 اولCharacterisation of weathered clayey soils responsible for shallow landslides
Shallow earth translational slides and earth flows, affecting colluvial soils derived by the weathering of the clayey bedrock, are a recurrent problem causing damage to buildings and roads in many areas of Apennines. The susceptibility assessment, e.g. slope stability models, requires the preliminary characterization of these superficial covers (lithology, geotechnical and hydraulic parameters)...
