Many attempts have been suggested to reduce the impact of modern conventional farming on the environment and semi-natural ecosystems. One of the attempts has been to introduce organic farming, which is known primarily for the absence of pesticides and artificial fertilising. The objective of this paper is to present differences found in the spontaneous vegetation and associated arthropods of comparable hedgerows situated within organic and conventional farming systems. We found significantly more plant and moss species in organic hedges, both in the individual plots, the individual hedges and when comparing the farming systems. Six species (Brachythecium rutabulum, Cerastium fontanum, Ranunculus repens, Cirsium arvense, Sonchus arvensis, Plantago... |

Many attempts have been made to reduce the impact of modern conventional farming on the environment and semi-natural ecosystems. One of them is organic farming, known primarily for the absence of pesticides and artificial fertilisers. The objective of this study was to study and test the differences in the spontaneous vegetation of comparable hedgerows in the same area situated within organic and conventional farming systems. The hedge bottom vegetation was surveyed during August 2001 in 13 hedgerows of each farming system. Farming type had not changed on either side of the hedgerows for the lifetime of the hedges (10-14 years). Sampling was associated with a set of 16 measured environmental variables. In the two farming systems hedgerows were comparable... |

The aim of the project was to compare flora and insect fauna of organic and conventional hedgerows and to study whether the drift of herbicides into hedgerows alone or in combination with differences in fertiliser application may explain any differences. The project consequently consisted of two parts, viz. collection of flora and insect data in existing hedgerows (multi-row hedgerows, age 10-15 years) on two soil types and an experiment in which a sown grassland vegetation was treated with combinations of glyphosate (0-25% label rate) and nitrogen (0-100 kg N/ha/year) as a simulation of the most important agricultural conditions having an effect on flora and insect fauna in different agricultural systems. In the experiment flora and insect fauna were... |
