Phosphate sorption by soils is one of the most important processes indicating the buffering power and availability of P for plants. Phosphorus sorption characteristics of eight representative calcareous soil of Isfahan region were evaluated. For this purpose, 3 grams, of < 2-mm soil were equilibrated for 24 hours at 25±l °C in 60 ml of 0.01 M CaCl2 with varying amounts of P. Sorbed phosphorus w...
soil particle-size distribution (psd) is one of the most important physical attributes due to its great influence on soil physical, chemical, and biological properties. water infiltration rate, land-use change, soil erosion, and biological soil crusts (bscs) may influence psd in a soil. the multifractal measures were useful tools in characterization of psd in soils. the objective of the current...

The paper deals with the influence of soil genesis on the physical-mechanical properties. The presented case study was conducted in the region of the Ostrava Basin where there is a varied genetic composition of the Quaternary geological structure on the underlying Neogeneous sediments which are sediments of analogous granulometry but different genesis. In this study, 7827 soil samples of an eol...
In tropical rainforests, termites constitute an important part of the soil fauna biomass, and as for other soil arthropods, variations in soil composition create opportunities for niche partitioning. The aim of this study was twofold: first, we tested whether soil-feeding termite species differ in the foraging substrate; second, we investigated whether soil-feeding termites select their foragin...
The effects of different mulch materials applied to compacted and uncompacted soil on the quantity and the quality of deposited earthworm casts were investigated. Biochemical properties and water stability of soil aggregates were compared with the corresponding properties of worm casts. This short-time experiment was conducted in the laboratory, simulating field conditions of mulch management i...

tially variable soil properties that affect crop yield to better optimize crop productivity and to maintain the Crop yield inconsistently correlates with apparent soil electrical sustainability of agriculture. conductivity (ECa) because of the influence of soil properties (e.g., Site-specific crop management is the management of salinity, water content, texture, etc.) that may or may not influe...
When aerial parts of the plants capable of storing absorbing mineral salts in their leaves fall, these dissolved materials are transferred to the soil surface, changing its physical and chemical properties. In this study, we have investigated the influence of the Haloxylon tree on the physical and chemical properties, and also humidity of the soil using two, 300 m long transects one canopy of t...
sange siyah dam is located two kilometers down the kabod khani village. the environ of ghorrve city in kurdestan province. this is an clay core dam. in this dam instrumentation is performed in three section and consist of electrical piezometers, total pressure cells, settlement cells and so on. the main objective of instrumentation is to control the behavior of dam body and foundation, end else...
