The fifth canonical correlation was driven by CMD, BlLS and WLS on the one side and soil moisture, weeds and ecozone on the other side. It confirmed the findings by stepwise regression analysis, but put more emphasis on the relation between WLS and weeds, and BlLS and ecozone, while it revealed a before not found correlation of higher severity of WLS with moist soils, of BlLS with weedy fields and of CMD with more humid ecozones.
