Macroscopic-to more recent molecular scale investigations have enhanced our knowledge
of soil phosphorus (P) chemistry, including the retention/release mechanisms in soils and …

Large amounts of biosolids are produced as a by-product of municipal wastewater
treatment. They are composed of about 50% organic and 50% inorganic material. The …

The capacitance (CAP) method and time domain reflectometry (TDR) are two popular
electromagnetic techniques used to estimate soil water content. However, the frequency …

Abstract The Standards, Measurements and Testing (SMT) harmonized procedure for
phosphorus fractionation in freshwater sediments (SMT protocol), which was developed …

Imbalanced nutrient management has caused soil phosphorus (P) to become an
environmental rather an agronomic problem in more economically developed countries …

Aims The objectives were to investigate (i) the forms and release pattern of P from an ash-
rich biochar-amended sandy soil;(ii) the transformation of biochar P in a soil-plant system …

Laws mandating phosphorus (P)‐based nutrient management plans have been passed in
several US Mid‐Atlantic states. Biosolids (sewage sludge) are frequently applied to …

Continuous addition of municipal biosolids to soils based on plant nitrogen (N) requirements
can cause buildup of soil phosphorus (P) in excess of crop requirements; runoff from these …

The effect of different treatments on the fate of applied P was investigated in a long-term field
experiment started in 1972–1973 following a maize–wheat sequence. The soil samples …

Fertilizers have been largely responsible for the massive increases in world food production
in the past half century that permitted accelerated global population growth to current …
