متن کاملRelease potential of phosphorus in Florida sandy soils in relation to phosphorus fractions and adsorption capacity.
Information on P release potential in relation to labile P and P fractions in sandy soils is limited. In this study, P release potential was determined by leaching, and labile P, soil P fractionation, and P adsorption capacity were measured in the laboratory using 96 Florida sandy soil samples to evaluate the relationship between P release in water and soil P status. The sandy soils had a very ...
متن کاملBiological and geochemical controls on phosphorus fractions in semiarid soils
This study examined the concentration of organic and inorganic phosphorus in surface soils of a Bouteloua gracilis-Bouteloua eriopoda grassland, and a Larrea tridentata shrubland, in the northern Chihuahuan Desert, New Mexico, USA. In this desert where the grassland vegetation has a uniform spatial distribution and individual shrubs have a patchy spatial distribution across the landscape, veget...
متن کاملcontribution of inorganic phosphorus fractions to plant nutrition in alkaline-calcareous soils
to evaluate the relationships between soil inorganic phosphorus p (pi) fractions, the soil p test and plant parameters such as plant p uptake, dry matter yield, tissue p concentra-tion and relative yield, glasshouse experiments and chemical analyses were conducted on 13 calcareous soils from six agricultural and seven adjacent bushland (virgin soil) sites. four rates of p (0, 15, 30, 60 mg/kg s...
