Data from: Chemical extraction of phosphorus from dairy manure and utilization of recovered manure solids

This is digital research data corresponding to a published manuscript, Chemical extraction of phosphorus from dairy manure and utilization of recovered manure solids. Agronomy 2020, 10, 1725; doi:10.3390/agronomy10111725 Repeated land application of dairy manure can increase soil phosphorus above crop requirements because of manure's low nitrogen (N) to phosphorus (P) ratio (N:P < 4:1). This soil P build-up can lead to off-site P transport and impairment of surface water quality. We evaluated a treatment process to extract P from manures, called Quick Wash, integrated with a double-stage solids separation system to recover coarse and fine manure solids. The Quick Wash process uses a combination of acid, base, and organic polymers to extract and recover P from manures, improving the N:P ratio of recovered manure solids (RMS)
