Weed and insect management alter soil arthropod densities, soil nutrient availability, plant productivity, and aphid densities in an annual legume cropping system
Applied Soil Ecology(2018)
摘要
•Weed management and soil insecticide had virtually no interactive effects.•Negative effects of weed management were related to the presence of weeds.•Weed presence had a beneficial effect on soil K at the site with sandy soil.•Aphid density and soil P were lower and plant biomass higher in +insecticide plots.•Collembola densities in yr 1 were negatively related to nodule densities in yr 2.
