“…Swine waste has increased from 2834 MT in 1992 to over 178,313 MT in 2007 (Turner, 2005; NASS, 2007). In the Oklahoma Panhandle, nearly all of the swine waste is stored in open‐air lagoon systems (Carreira et al, 2006). When properly applied and remunerative, swine lagoon effluent (SE) can be used as manure with minimal environmental and nuisance concerns, such as odor (Al‐Kaisi and Waskom, 2002).…”

Economic Profitability of Sustained Application of Swine Lagoon Effluent and Beef Feedlot Manure Relative to Anhydrous Ammonia in the Oklahoma Panhandle

With the rapid growth of swine (Sus scrofa domestica) production in the Oklahoma Panhandle, animal waste management has become a growing concern. Field experiments were conducted to evaluate the long-term eff ects of equivalent nitrogen rates of swine lagoon effl uent (SE), beef manure (BM), and commercial fertilizer on the yield and economic returns of irrigated corn (Zea mays L.) grown on calcareous Gruver silt loam soil (fi ne, mixed, superactive, mesic Aridic Paleustoll) near Goodwell, Oklahoma. A randomized, complete-block, split-plot design with three replications was used to test the main eff ects of N source (NS) and equivalent N application rates (NR) of 56, 168, and 504 kg N ha -1 . Both BM and SE generated signifi cantly (P < 0.05) higher corn yields than anhydrous ammonia (AA) across the main eff ect of NS. Greater separation of mean corn yields was found among NS as the equivalent NR rate was increased from 56 to 504 kg N ha -1 with the following rankings (P < 0.05): AA = BM = SE at 56 kg N ha -1 , BM = AA ≥ SE at 168 kg N ha -1 , and SE > BM > AA at 504 kg N ha -1 . Both SE and BM generated signifi cantly (P < 0.05) higher economic returns than AA. Th e highest ranked alternatives of economic returns were generated by SE×504 and BM×168. Results indicate that SE and BM can be economically viable substitutes for commercial fertilizer, bringing higher yields and economic benefi ts to producers in the Oklahoma Panhandle. ).Abbreviations: AA, anhydrous ammonia; BM, beef manure; IRR, applied irrigation; NR, equivalent nitrogen rates; NS, nitrogen source; N56, nitrogen applied at 56 kg N ha -1 ; N168, nitrogen applied at 168 kg N ha -1 ; N504, nitrogen applied at 504 kg N ha -1 ; SE, swine lagoon effl uent; YR, year.

“…Manure can substitute for commercial fertilizers by supplying the multiple essential crop nutrients (such as nitrogen, phosphorus, potassium, sulfur, calcium, magnesium, and micronutrients) contained in animal wastes. Swine effluent has sufficient phosphorus that the level of phosphorus is expected to increase over time (Carreira et al, 2006), but we do not address potential problems created by the build-up of phosphorus in the soil.…”

A Cox nonnested test is conducted using a fast double bootstrap (FDB) method to select among three competing functional forms (linear response plateau, quadratic, and Mitscherlich-Baule) to model forage yield response to nitrogen applied with swine effluent. The quadratic is rejected in favor of one of the other functional forms in all cases. The FDB p values differed slightly from the single bootstrap p values. Buffalograss was slightly more profitable than bermudagrass and has the ability to use almost as much nitrogen as bermudagrass.
