  1. Reduce fertilizer, pesticide or herbicide use generally

    A replicated, controlled study in 2000-2001 on cereal fields of three different farms in western Germany (Wehke et al. 2006) found that both plant species richness and vegetation cover was higher in plots not sprayed with herbicide (spray windows) than in the sprayed part of the field centre. The increase in species richness in spray windows was similar for all five different plant categories considered. Whereas vegetation cover of herbs increased from 10% (field centre) to 50% (spray windows), no such increase was observed for grass cover. Note that no statistical analyses were performed on these data. Spray windows were created as unsprayed plots in the centre of arable fields on one integrated and two conventionally managed farms. Plant species richness and vegetation cover were recorded in both ‘spray windows’ and the sprayed part of the field. Plants were categorized as belonging to five different groups: Red-listed species, declining species, unthreatened arable weeds, arable ruderal species and non-arable ruderal species. Information about crop rotation and herbicide application was obtained directly from the farmers.
