Agricultural land is a more important resource biodiversity and changes in their dispersion and structures reflected the quality of habitats. A suitable bioindicator pointing to such changes is the taxon Araneae. The aim of our research was to point out the dispersion of Araneae individuals in the ecological and conventional farming conditions and also the influence of pH, potassium, phosphorus, nitrogen on their abundance. During the years 2018 to 2021, we caught 2,862 individual Araneae in ecological farming (Pisum sativum, Grass mixture, Triticum spelta and T. aestivum) and conventional farming conditions (Brassica napus, Hordeum vulgare and Zea mays) using the pitfall trap method. The dispersion of Araneae individuals was the highest around crops in ecological farming. We confirmed a declining number of individuals with decreasing values of potassium, phosphorus and nitrogen in conventional and also ecological farming. However, the difference was within the limits of optima phosphorus, potassium and nitrogen, which were lower in ecological farming compared to integrated farming. On the basis our results, both types of farming can be evaluated as homeostatically, which affects the dispersion and abundance of Araneae. Providing them with topical and trophic conditions, which is important for the production of biomass and also affects the crop.
