Cadmium availability from granulated and bulk-blended phosphate-potassium fertilizers.
Recent field experiments have shown that high chloride (Cl) in irrigation waters can increase soil cadmium (Cd) uptake by crops because of the formation of soluble ion-pair complexes of Cd with Cl in soil solution. The present study was aimed at testing a hypothesis that KCl in granulated PK fertilizers may enhance Cd uptake by crops from Cd-containing P fertilizers because of close contact bet...
متن کاملCadmium contamination of agricultural soils and crops
23 The biogeochemistry and bioavailability of cadmium, released during sphalerite 24 weathering in soils, were investigated under contrasting agricultural scenarios to assess 25 health risks associated with sphalerite dust transport to productive soils from mining. 26
متن کاملCadmium Levels in Soils and Crops in the United States
The concentrations of cadmium in agricultural soils depend upon the amounts present in the parent rocks from which the soils form, the amounts added in the form of fertilizers and soil amendments, the amounts deposited onto soils from the atmosphere, and the amounts removed by harvested crops and by leaching. On average, sedimentary rocks contain greater concentrations of Cd than either igneous...
متن کاملFertilizer usage and cadmium in soils, crops and food
Phosphate fertilizers were first implicated by Schroeder and Balassa in 1963 for increasing the Cd concentration in cultivated soils and crops. This suggestion has become a part of the accepted paradigm on soil toxicity. Consequently, stringent fertilizer control programs to monitor Cd have been launched. Attempts to link Cd toxicity and fertilizers to chronic diseases are common. A re-assessme...
