Abstract:

Biochar is used as a solid amendment to stabilize the soil nutrients in otherwise nutrient - deficient soils. In the present study, the mobility of soil phosphorous and phosphomoonoestrases were monitored with respect to biochar amendment. Biochar amendment was used at different application rates with soil and soi sludge mixtures. Soil samples collected at different time intervals were evaluated for phosphorus levels and (acidic and alkaline) phosphatases enzyme activities. The entire data set was subjected to kinetic modeling and results showed that the data was best described by parabolic di

Abstract:

SUMMARYField studies of the dynamics of transformation and availability of applied phosphorus in a Vertisol cropped with rainfed cotton showed that phosphorus application increased available phosphorous in the soil. However, 70–80% of the phosphorus was fixed when more than 40 kg P2O5 ha−1 was applied. Maximum uptake of phosphorus by cotton occurred during the active growth period 40 to 80 days after germination, as reflected in a steep decline in the labile pool of available phosphorus in the soil. Over 50% of the total inorganic phosphorus occurred as Ca-P, which was the major contributor to

Abstract:

Abstract Sorption capacity and the energy of phosphorus adsorption on muck and peat deposits were studied in peat- -muck soil profile from a lowland peatland in the Kuwasy object. Soils of the area are characterised by a laminar structure which results in variable sorption properties of peat deposits of different origin, degree of humification (decomposition - R) and transformation of organic matter of upper muck layers (degree of mucking - Z). There was a relationship between the maximum phosphorus adsorption calculated from the Langmuir isotherm (b) and adsorption energy (k) and the type and

Abstract:

Short-chain polyphosphate fertilizers have been increasingly applied in agriculture, but little is known about the chemical behaviors of polyphosphate in soils. Herein, a cylinder experiment was carried out to investigate the influences of different P types (i.e., mono-ammonium phosphate (MAP), phosphoric acid (PA) and ammonium polyphosphate (poly-P)) and their application methods (single vs split) on the mobility and availability of P in soil through a column millimeter-scale slice cutting method; meanwhile a soil microcosm experiment (560-day) was conducted to investigate the effects of diff

Abstract:

Calcareous soils with high background cadmium (Cd) levels are widely distributed in south-west China and soil acidity is a major environmental problem. However, little effort has been made to study the changes in chemical speciation as affected by soil acidification other than by acidic rain. In the present study, we investigated the impact of mono-ammonium phosphate (MAP) and phosphoric acid on soil pH and chemical transformation of Cd in calcareous soils. Calcareous soils collected from south-west China were treated with three concentrations (0.1, 0.2 and 0.4 mol kg–1 soil) of MAP and phosph

Abstract This paper investigates the effect of phosphorus on nitrogen migration and transformation during the sewage purification processes in deep subsurface wastewater infiltration systems. Good performance was achieved with a hydraulic loading rate of 0.1 m3/m2·d, indicating that the effluent water quality could meet the primary grade A values as put forth by the ‘Cities Sewage Treatment Plant Pollutant Discharge Standard’ (GB18918-2002). In addition, the results of three inflow total phosphorus (TP) concentrations (5 mg L−1, 15 mg L−1, and 30 mg L−1) indicated that high-levels of phosphoru

Abstract:

Although the application of biological materials has shown potential in improving the environment of salinized soil, the impact on the transformation of soil phosphorus forms in salinized soil, especially when combined with B. mucilaginosus (BM), has rarely been studied. Therefore, this study investigated soil’s properties and phosphorus forms, as well as their relationship, in salinized soil after the application of different biological materials, including rice straw (RS), biochar (B), acidified biochar (AB), BM, RS+BM, B+BM, and AB+BM. A sequential extraction procedure was employed to deter
