| dc.description.abstract | In search of manure disposal methods that decrease environmental impacts and benefit dairy producers, this study examines the possibilities of using turfgrass as a potential "crop" for removing P in dairy (Bos taurus) manure applications. 'Tifway' bermudagrass (Cynodon dactylon L. x C. transvaalensis Burtt-Cavey), 609 buffalograss (Buchloe dactyloides (Nutt.) Engelm.), and 'Reveille' bluegrass (Poa arachnifera Torr. x P. pratensis L.) were established and subjected to six treatments: a control, 100 and 200 kg P ha⁻¹ yr⁻¹ applied as manure with and without supplemental N fertilizer, and N fertilizer with one application of 100 kg ha⁻¹ K. These excessive P rates were used to insure that P in soil exceeded legal limits. Clippings and sod were removed and analyzed for total N, P, K to quantify the fate of nutrients during sod production and a single sod harvest. Sod strength and weight were also evaluated. The total P removal rates in manure treated sod ranged from 35 to 76% above the total P that was already present in soil. None of the manure treatments significantly affected sod strength. Sod weight differed among treatments of bluegrass only. Sod weights from treatments that received manure were an average of 0.65 kg 0.09m⁻² lower than the control. Manure P can be removed and exported in sod, but additional research is needed to optimize sod productivity and quality and the economic feasibility of turfgrass systems that use manure source of nutrients. | en |
