Nitrate leaching from organic arable crop rotations is mostly determined by autumn field management Organic Eprints
Askegaard, Margrethe; Olesen, Jørgen E.; Rasmussen, Ilse A.; Kristensen, Kristian.
Two main challenges facing organic arable farming are the supply of nitrogen (N) to the crop and the control of perennial weeds. Nitrate leaching from different organic arable crop rotations was investigated over three consecutive four-year crop rotations in a field experiment at three locations in Denmark (12 years in total). The experimental treatments were: i) crop rotation, ii) catch crop and iii) animal manure. Nitrate leaching was estimated from measured soil nitrate concentation in ceramic suction cells and modelled drainage. There were significant effects on annual N leaching of location (coarse sand > loamy sand > sandy loam) and catch crops (without > with). Including a grass-clover green manure on 25% of the area did not increase N...
