The soils of Ganges River Floodplain (GRFP), an important crop growing zone the country, are known to be widely deficient in micronutrients. study was conducted relate distribution and fate soil micronutrients relation land type, properties cropping practices GRFP.A total 52 locations were selected for sample collection from across GRFP, varied series pattern, analysed DTPA extractable iron (Fe...

Acidic soils need to be improved of pH in order maintian sustainable agricultural production. In ameliorate the pH, lime, available Ca and some other properties acidic soils, materials that increase soil value are needed. One these organic substances is gyttja. Gyttja contains 30-40% CaCO3 40-50% matter, which generated as waste Af?in Elbistan thermal power plant its reserve estimated 4.8 billi...

the potential risk of metal accumulation in periurban agricultural areas is a matter for concern.the climate characteristics and carbonate content of calcareous agricultural mediterranean soils typical inthese areas favour metal accumulation at the surface level; however there is also a risk of potential metalmobility. our study focuses on the soil properties affecting metal mobility in these s...

Dispersion and runoff of mine tailings have serious implications for human and ecosystem health in the surroundings of mines. Water, soils and plants were sampled in transects perpendicular to the Santiago stream in Zimapan, Hidalgo, which receives runoff sediments from two acidic and one alkaline mine tailing. Concentrations of potentially toxic elements (PTE) were measured in water, soils (rh...

Abstract Management of soil micronutrients for better crop production needs a sound understanding their status and causes variability. This is more relevant acid soils the mountain ecosystem Eastern Himalaya (Northeast India). We assessed status, effect land uses along altitudinal gradients (14 to 4090 masl) on properties micronutrient concentrations (DTPA extractable Fe, Mn, Cu, Zn) across reg...

zinc (zn) availability and mobility in soils is controlled by its interaction with the soil matrix and amendments. contradicting evidence has been reported for factors influencing zn behavior in soils. the aim of this study was to investigate the zn sorption in selected acid, calcareous and gypsiferous soils with different background electrolytes (na+, k+ and h2po4, no3 and cl backgrounds). iso...
