dc.description.abstractIn the NW region of Portugal a very intensive dairy farming system has been developed based on two silage crops per year (maize plus a winter crop), which has important risks of nitrate leaching losses during the winter season. These soils receive N inputs as high as 600-730 kg N ha -1 yr -1 resulting from two applications of dairy-cattle slurry just before sowing each crop, and 220-300 kg N ha -1 yr -1 from mineral fertilizers (Trindade et al., 1997). The objectives of our study were to evaluate the effect of cattle-slurry rate and time of application on nitrate-N concentration of drainage water during the winter crop (Lolium multiflorum Lam.) growth period.por
