The organic farmland is increasing all the time and the goal is that 15 % of the Swedish farmland will be in organic production in year 2010. The organic production needs new and more effective ways to control weeds, and there is the row harrowing coming as a good complement to the conventional weed harrowing. In this experiment is weed harrowing whit different row spaces and row harrowing with a spacing of 25 cm compared. Then are the weed picked and the weight taken of them. The yield is compared in the 7 different ways of treatment. The results is not showing any significant differences in yield even when the row spacing is 25 cm instead of 12,5 cm. Even the spring wheat that is a sensitive crop and has bad tillering is doing well in this experiment. Now with modern technology where the row harrow is controlled by a camera that making the row harrow to follow the rows is it the soil coverage of the crop that is the limit for the speed. With wide machinery is the very good coverage even with a row harrow.
