Reduce fertilizer, pesticide or herbicide use generally

A before-and-after study in an arable field in England (Frampton 2002) found that abundance and diversity of springtails (Collembola) was significantly lower under conventional pesticide applications than reduced applications (no insecticides, minimal herbicides and fungicides). The springtail Entomobrya nicoleti disappeared from the plot with conventional pesticide application during the first year and did not recover during the three year study. There was no evidence of an effect on populations of the springtail E. nicoleti at the field edge. Lepidocyrtus spp also declined with the conventional spraying regime in the field but not at the field edge. Orchesella cincta and Tomocerus spp were found only in field edge samples. Half of a field (grass and winter wheat rotation) received conventional pesticide applications, and the other half received reduced input, insecticides were excluded from a 6 m headland around the crop (1991-1996). Treatments were reversed 1996-1999. Arthropods were monitored on three occasions/year using suction sampling (25-125 m each side of a hedgerow) and pitfall traps 75 m from hedgerow and at the field edge adjacent to a ditch beside the hedgerow.
