Book Synopsis Effects of Liquid Swine Manure Placement and Rate on Phosphorus Loss with Runoff Water [microform] by : Tabbara, Hadi
Download or read book Effects of Liquid Swine Manure Placement and Rate on Phosphorus Loss with Runoff Water [microform] written by Tabbara, Hadi and published by Ann Arbor, Mich. : University Microfilms International. This book was released on 2000 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Total suspended solids (TSS) concentrations and mass losses in runoff water were significantly greater for the liquid fertilizer treatment in comparison with manure treatment. Concentrations and total losses of all P forms with runoff water were significantly greater for fertilizer treatment in comparison with manure. These losses were significantly less when manure or fertilizer was incorporated. Concentrations of all P forms were significantly greater for the higher rates of application, but similar effects on mass losses were only found for total phosphorus, particulate phosphorus, and bioavailable phosphorus (BAP). Soil test for P(STP) by agronomic and environmental tests showed that dissolved P (DP) and BAP concentrations in runoff water were best predicted by Bray 1-P or iron oxide strip-P in soil. DP and BAP total losses with runoff water were well correlated (r> 0.85) with Bray 1-P, iron oxide strip-P, and water extractable P in soil.
