The effect of the nitrogen (N) supply from hairy vetch grown as winter green manure on white cabbage was investigated in field trials performed on an organic farm in north-west Germany over two years. Hairy vetch was either used as green manure or harvested. One of two bare-soil fallow treatments was supplied with hairy vetch shoot mass to serve as reference. In 2002 and 2003, hairy vetch and weeds accumulated 136 and 178 kg ha-1 of shoot N and yielded 3.79 and 4.72 t ha-1, respectively. After ploughing and planting white cabbage (Brassica oleracea L. convar. capitata var. capitata f. alba) for sauerkraut production at the beginning of June, the amount of soil mineral N (SMN) of the topsoil layer was biweekly investigated until canopy for about 6 - 8... |
