However, there is limited field evaluation of its impact on commercial vineyard level. Our study evaluates the (i) effects of two soil management (permanent and alternative vegetation cover and bare soil) in vineyard inter-rows and (ii) effects of surrounding landscape complexity on biota richness (bees, earthworms, plants) and production parameters in sixteen commercial vineyards in Central Romania. Biota richness (bees, earthworms, plants) and abundance are influenced by vineyard management intensity. Biodiversity is higher in low intensity vineyards (alternative or permanent cover crop) than in high intensity (bare soil). In this study, management practices seem to have more influence on vineyard inter-row biodiversity and on quality parameters of grapes than surrounding landscape

However, our knowledge of potential side-effects on non-target soil organisms, even on such eminent ones as earthworms, is still very scarce. In a greenhouse experiment, we assessed the impact of the most widely used glyphosate-based herbicide Roundup on two earthworm species with different feeding strategies. We demonstrate, that the surface casting activity of vertically burrowing earthworms (Lumbricus terrestris) almost ceased three weeks after herbicide application, while the activity of soil dwelling earthworms (Aporrectodea caliginosa) was not affected. Reproduction of the soil dwellers was reduced by 56% within three months after herbicide application. Herbicide application led to increased soil concentrations of nitrate by 1592% and phosphate by 127%, pointing to potential risks for nutrient leaching into streams, lakes, or groundwater aquifers. These sizeable herbicide-induced impacts on agroecosystems are particularly worrisome because these herbicides have been globally used for decades.
