Manures behave similar to superphosphate in phosphorus accumulation in long-term field soils
Repeated application of manures to agricultural soils could cause the accumulation of phosphorus (P) in soils. However, it is unclear if manure P can behave similar to P in soluble fertilizers in accumulation Olsen-P (0.5 mol L-1 NaHCO3 at pH 8.5) in soils. A long-term wheat-maize rotation experiment was conducted to investigate the effects of repeated application of manures on P accumulation i...
متن کاملStudy of the Phosphorus Sorption Behaviour in the Cultivated and Virgin Soils of Khoy Region
To study the behaviour of phosphorus (P) sorption in the agricultural soils of Khoy region and the effect of long-term cultural management with the application of poultry manure on the P sorption parameters, bath experiments were carried out with 16 soil samples (8 cultivated and 8 virgin soils) and 9 initial P concentrations from 0 to 30 mg L-1 in 0.01M CaCl2 as a background solution. After eq...
متن کاملThe composition, leaching, and sorption behavior of some alternative sources of phosphorus for soils
Concerns about the sustainability of inorganic fertilizers necessitate the characterization of alternative P source materials for agronomic P-efficiencies and P losses via leaching. Firstly, this study examined nutrient compositions including P speciation of seven soil amendments: sewage sludge (SS), anaerobic digestate (AD), green compost (GC), food waste compost (FWC), chicken manure (CM), bi...
متن کاملPhosphorus speciation of clay fractions from long-term fertility
19 Phosphorus (P) losses from agricultural soils constitute a main driver for eutrophication of the 20 Baltic Sea. There is limited knowledge about sorption and release processes of P in these soils, 21 especially concerning the effects of fertilization. In this study, P speciation of the clay fractions 22 from six different soils in long-term fertility experiments in Sweden was investigated by...
متن کاملField-scale evaluation of phosphorus leaching in acid sandy soils receiving swine waste.
Accurate descriptions of P leaching are important because excess P applied to soils can enter surface water via leaching and subsurface transport, thereby negatively impacting water quality. The objectives of this study were to monitor P leaching in soils with a long-term history of waste application, relate soil solution P concentrations to soil P status, and quantify P leaching losses. Soil s...
