Data from: Annual ryegrass (Lolium multiflorum Lam.) growth response to nitrogen in a sandy soil amended with acidified manure and municipal sludge after “Quick Wash” treatment

The Quick Wash (QW) treatment extracts phosphorus (P) from manure and
municipal sludge (MS), producing an organic acidified by-product with
adequate nitrogen (N):P ratio to meet crop N requirements. Yet, data on
crop response to N using QW by-products are lacking. We evaluated the
response of annual ryegrass (Lolium multiflorum Lam.) and
potential N leaching in sandy soil to N applications using raw wastes,
their corresponding QW by-products, and ammonium sulfate (AMS) fertilizer.
Treatments included a control (no amendment added), raw and acid-washed
chicken litter, dairy and swine manure, MS, and AMS at 100, 200, and 400
kg N ha−1.
