release phosphorus during this phase at a rate of 0.4 to 0.5 milligrams of phosphorus for every milligram of acetate consumed. The result is a net increase in the amount of dissolved phosphate across the anaerobic phase of the process.

Phosphorus is lost from agricultural land to surface water bodies in sediment-bound and dissolved forms. Sediment-bound P includes P associated with minerals and organic matter. Dissolved P constitutes 10 to 40 percent of the P transported from most cultivated soils to water bodies through runoff and seepage (Sharpley et al., 1992).READ MORE
Phosphorus is one of the main fertilizer elements (often seen as the letter "P"), the second number of three in the analysis on fertilizers.
