Weed vegetation in organic winter cereals in the region of Mecklenburg- Vorpommern as influenced by site and management

Abstract

Arable weeds are important theme in organic farming. In this study the weed densities and diversity in Mecklenburg-Vorpommern were studied. To achieve this, 17 fields of winter cereal on organic farms in the region were surveyed. Consequently the density of weeds was estimated within these fields in the months of June and July in 2016. This was combined with the management and site information of the surveyed fields. In total 69 different weed species were found. This was followed by an analysis of the effect of the soil and management variables on the weed density and diversity. From this analysis we found some significant influence of site and management variables.
