| In comparison to harvesting, grazing is less cost intensive. For economical reasons an extended duration of grazing period is recommended. Grazing during winter can cause pasture damages, which is of minor relevance for older grass clover grown on arable land, which will be ploughed in the following spring. Against this background yield and forage quality of 3 different legume species, i.e. white clover, red clover and alfalfa, grown in binary mixtures with two grass species, perennial ryegrass and tall fescue, respectively, were examined before grazing the third growth in autumn or winter. Nitrate leaching losses during winter and yield of the following spring wheat were recorded. Yield and forage quality of the total sward was not significantly... |

| Due to etching effects on broad leafed weeds, fine ground kainite was used for weed control before synthetic herbicides have become common practice in conventional farming. According to the organic standards kainite can be used as potassium fertiliser. The present study investigates optimal growing stages for application in organic winter wheat and the range of effectiveness. Kainite was applied at a rate of 800 kg per hectare alternatively at EC 29 and EC 30 under the conditions of morning dew on days with high sunshine duration. At both growing stages kainite application reduced the population of hairy vetch, chamomile, cornflower, field pansy, winter rape, common chickweed and persian speedwell. Application at early growing stages led to a... |
