Impact of chemical amendment of dairy cattle slurry on phosphorus, suspended sediment and metal loss to runoff from a grassland soil [PDF]

, 2011
peer-reviewedEmerging remediation technologies such as chemical amendment of dairy cattle slurry have the potential to reduce phosphorus (P) solubility and consequently reduce P losses arising from land application of dairy cattle slurry. The aim of this

Phosphorus availability in soils amended with wheat residue char [PDF]

Biology and Fertility of Soils, 2012
Plant availability and risk for leaching and/or runoff losses of phosphorus (P) from soils depend among others on P concentration in the soil solution. Water-soluble P in soil measures soil solution P concentration. The aim of this study was to understand the effect of wheat residue char (biochar) addition on water-soluble P concentration in a wide ...

Interpretation of soil phosphorus availability by Mehlich-3 in soils with contrasting phosphorus buffering capacity [PDF]

Revista Brasileira de Ciência do Solo, 2020
ABSTRACT Increasingly rational use of phosphate fertilizers by agriculture is important, especially in Brazil, due to its importance for global food security and its high dependence on phosphate fertilizers for crop production. Thus, correlation and calibration researches with soil available phosphorus (P) extractants to improve the recommendation and ...

Phosphorus sorption, accumulation and leaching [PDF]

, 2003
Arable land is a major diffuse source of P loads to surface waters. The main processes for P losses from agricultural fields are erosion, surface runoff and subsurface leaching.

Enhancing phosphorus availability and dynamics in acidic soils through Rice straw biochar application: a sustainable alternative to chemical fertilizers

Frontiers in Sustainable Food Systems
Phosphorus is a vital nutrient for crop growth, but its bioavailability is often limited in acidic soils, which are prevalent in many agricultural regions, including South China.

Soil phosphorus dynamics as affected by Congo grass and P fertilizer

Scientia Agricola, 2014
Some plant species can change soil phosphorus (P) availability and this may be an important tool in managing tropical high fixing phosphorus soils. An experiment was conducted to evaluate phosphorus transformations in the soil and phosphatase activity ...

Improving Phosphorus Availability in an Acid Soil Using Organic Amendments Produced from Agroindustrial Wastes

The Scientific World Journal, 2014
In acid soils, soluble inorganic phosphorus is fixed by aluminium and iron. To overcome this problem, acid soils are limed to fix aluminium and iron but this practice is not economical. The practice is also not environmentally friendly.
