Broiler litter, a mixture of manure, wasted feed, and bedding materials, is used widely as fertilizer on pasture lands in south central Mississippi. Studies suggest overseeding bermudagrass (warm season) with annual ryegrass (cool season) is an effective strategy for remediation of manure-impacted soils. This research determined the effects of ‘Marshall' annual ryegrass on soil nutrient levels following the cessation of litter applications to ‘Coastal' bermudagrass. Whole plots (4 x 6 m) that in previous three years had received 0, 4.5, 9, 18, and 36 Mg ha^-1 were split and annual ryegrass was sown to half of each plot in fall 2001, 2002, and 2003. Plots were subsequently provided 67 kg N ha^-1 (34-0-0) in summer following each bermudagrass harvest. Results for surface soils, 0-5 cm depth, indicated values for total N and plant available P and K (Mehlich 3 extractant) increased linearly as litter rate increased. In treatments provided <36 Mg litter ha^-1 yr^-1, soil P was somewhat lower in bermudagrass-ryegrass than bermudagrass; however, the rate of ‘drawdown' in soil P over time did not differ between these systems. Interestingly, the largest changes in soil P and K levels were observed at 36 Mg ha^-1 litter, presumably from the removal of high biomass due to increased soil fertility. Because bermudagrass-ryegrass system removed significantly more P, but did not have faster drawdown rate of soil P than bermudagrass, the benefits of annual ryegrass for remediation of manure-impacted soils appear to have more to do with additional hay production and removal of nutrients than with reduction in soil P levels.
