Effect of mineral and manure phosphorus sources on runoff phosphorus.
Concern over nonpoint-source phosphorus (P) losses from agricultural lands to surface waters has resulted in scrutiny of factors affecting P loss potential. A rainfall simulation study was conducted to quantify the effects of alternative P sources (dairy manure, poultry manure, swine slurry, and diammonium phosphate), application methods, and initial soil P concentrations on runoff P losses fro...
متن کاملPhosphorus Interactions with Other Nutrients
one production factor influences the response to another factor. A positive interaction occurs when the influence of the combined practices exceeds the sum of the influences of the individual practices. Such positive interactions have served as the science-based justification for development of a “balanced” plant nutrition program. Positive interactions with P and other nutrients are well docum...
متن کاملPhosphorus Recovery from Animal Manures using Optimized Struvite Precipitation
The over-application of phosphorus, as manure by animal feeding operations, is a threat to surface water quality. Concentration of animal feeding operations and over application of manures to cropland has lead to a build-up of phosphorus on many farms (Greaves et al., 1999). Relative to crop needs, manure slurries contain higher levels of phosphorus than nitrogen. When manure is applied to meet...
متن کاملPhosphorus Recovery from Wastewater by Struvite Crystallisation: a Review
The present review provides an understanding of principles of struvite crystallisation and examines the techniques and processes experimented to date by researchers at laboratory, pilot and full scale to maximise phosphorus removal and reuse as struvite from wastewater effluents. Struvite is mainly known as a scale deposit causing concerns to wastewater companies. Indeed struvite naturally occu...

fate) reduced WEP concentrations in the litter relative to untreated chicken litter. Similarly, when alum-treated Water-extractable P (WEP) in manure is increasingly used as an and untreated litters were broadcast onto pastures, difenvironmental indicator as it is correlated with P in runoff from soils recently amended with manure. Little information exists on WEP ferences in dissolved P concen...
