This article is from PLoS ONE, volume 9.AbstractAlternative forages can be used to provide valuable home-grown feed for ruminant livestock. Utilising these different forages could affect the manure value and the implications of incorporating these forages into farming systems, needs to be better understood. An experiment tested the hypothesis that applying slurries from ruminants, fed ensiled red clover Trifolium pratense, lucerne Medicago sativa or kale Brassica oleracea would improve the yield of hybrid ryegrass Lolium hybridicum, compared with applying slurries from ruminants fed ensiled hybrid ryegrass, or applying inorganic N alone. Slurries from sheep offered one of four silages were applied to ryegrass plots at 35 t ha−1 with 100 kg N ha−1 inorganic fertiliser; dry matter DM yield was compared to plots only receiving ammonium nitrate at rates of 0, 100 and 250 kg N ha−1 year−1. The DM yield of plots treated with 250 kg N, lucerne or red clover slurry was significantly higher than other treatments Pred clover 81 kg kale 44 kg ryegrass 26 kg ha−1 yr−1. These FNE values represent relative efficiencies of 22% ryegrass, 52% kale, 47% red clover and 60% for lucerne slurry, with the ryegrass slurry efficiency being lowest P = 0.005. Soil magnesium levels in plots treated with legume slurry were higher than other treatments P
