Understanding the distribution of different P forms in soil aggregate fractions is important in evaluating the risk of P run-off and leaching in the agricultural soils. The objective of the present research was to determine the effect of aggregate size on soil phosphorus availability and fractionation in 10 calcareous soils. Micro aggregate (< 0.25 mm), macro aggregate (> 0.25 mm) and whole soi...
Optimization of phosphorus (P) fertiliser use is desired to ensure more sustainable fertiliser, economic food production and reduction eutrophication water bodies. Presently, the Olsen P values on which recommendations are based achieve optimum yield frequently same for all soils. The aim this study was identify properties different soils that affect their critical in order develop better, soil...
Sustainable agriculture requires improved phosphorus (P) management to reduce the overreliance on P fertilization. Despite intensive research of root adaptive mechanisms for improving P acquisition, the inherent potential of roots for efficient P acquisition remains unfulfilled, especially in intensive agriculture, while current P management generally focuses on agronomic and environmental conc...
