Managing heavily manured soils for decreased P loss to waters requires improved understanding of the chemical and sorption-desorption characteristics of P in these soils. We used soils from agricultural fields receiving =8 yr of dairy, poultry, swine manure or spent mushroom compost for the determination of P functional groups in NaOH-EDTA extracts by solution 31P nuclear magnetic resonance (NMR) spectroscopy, degree of P saturation (DPS), and P sorption-desorption isotherms. The 31P NMR…

Systematic Study of Legacy Phosphorus (P) Desorption Mechanisms in High-P Agricultural Soils

Repeated manure additions containing phosphorus (P) in excess of crop needs have led to many agricultural soils with high levels of soil P (i.e., legacy P), particularly in the Delmarva region (USA).

Soil phosphorus sorption properties in different fertilization systems

The study aimed at the evaluation of the accumulation and vertical distribution of different forms of phosphorus (P) in reference to phosphorus sorption properties subject to mineral (NPK),

Phosphorus movement and speciation in a sandy soil profile after long-term animal manure applications.

Investigation of the mobility of both inorganic and organic P in profile samples from a noncalcareous sandy soil treated for 11 yr with excessive amounts of pig slurry, poultry manure, or poultry manure mixed with litter finds a strong downward movement of orthophosphate.

Amounts, Forms, and Solubility of Phosphorus in Soils Receiving Manure

Continually land-applying manure at rates exceeding crop removal can change soil P chemistry and increase soil P to levels that are of environmental concern. To assess the effect of long-term manure

Phosphorus speciation in manure-amended alkaline soils.

The results show that the P forms in solid and lagoon manure are similar, and the majority of organic P in the soils is phytic acid, which is enriched in the surface soils compared with the subsurface soils.

Wet chemical and phosphorus-31 nuclear magnetic resonance analysis of phosphorus speciation in a sandy soil receiving long-term fertilizer or animal manure applications.

The results suggest that long-term applications of large amounts of P fertilizer and animal manures caused an accumulation of in organic P, resulting in an increase of the potential risk related to mobilization of inorganic P in the top 5 cm of these soils.

This work investigated P release from the surface of a Denbigh silt loam from Devon and soils from Pennsylvania in relation to the concentration of P in surface runoff and subsurface drainage to determine a change point in STP, which may be used in support of agricultural and environmental P management.
