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...
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...

This was assessed by determining NaHCO3–extractable inorganic and organic P in a range of temperate pasture Soil is commonly stored in an air-dried state for extended periods soils extracted immediately after air drying and followbefore chemical analysis. The effect of storage on P solubility was assessed ing air-dry storage for 3 yr at ambient laboratory temperaby determining NaHCO3–extractabl...
