Abstract
Beef feedlot runoff retained in catchment lagoons was applied as an irrigant for bromegrass to determine the effects of this practice on bromegrass yields, bromegrass N, P, K concentrations and uptake, selected soil chemical properties, and groundwater quality beneath the application area. Average applications of 9.3 and 19.0 cm of diluted lagoon water, 9.5 and 16.6 cm of straight lagoon water, and 8.0 cm of well water in one irrigation season produced no consistent differences. Lagoon water applications produced an accumulation of extractable K in the soil profile. Analyses of groundwater samples from beneath the application area at depths of 7.6 and 21 m revealed highly significant differences between these depths relative to concentrations of NO3-N, Ca, Mg, K, Na, Cl-, and electrical conductivity values.
