Väderstad has been developing Spirit StripDrill for a number of years and has taken part in many trials in Denmark, Germany, Poland, Sweden and England.
“Compiling the results from all these trials shows a clear yield increase for oilseed rape from 3-10 per cent. And a slight increase for barley and wheat. For wheat, we see a range of results from no change to up 10 per cent increase, while the corresponding figure for barley is up to 40 per cent increase” said Crister Stark at Väderstad.
