One field is currently cropped with Vespa winter beans which will be compared to a neighbouring field which is cropped with Spring Oats and will be come into the same crop as the bean field next year. The field is principally untreated, with two treated tramlines which have been treated with a biostimulant called Biocat+.
It will be interesting to see if the biostimulant has an impact of bean yield and also try and quantify what level of nitrogen the beans fix.
