Agronomic and Environmental Availability of Biosolids-P (Phase-II)

Concerns about water quality degradation resulting from land appliation of manures and biosolids have elicited a wide array of national and state regulations. The regulations focus on P as the limiting nutrient to eutrophication of most freshwater supplies and threaten to severly impact biosolids recycling. Critical data about biosolids-P phytoavailability and run-off potential, especially field data, needed to validate the regulations are scarce. The goal of this reseach was to supply such...
