Ecosystem services have become a top research issue in ecology, economy, environment management, and policy. One of the important ecosystem services is biodiversity. Agricultural biodiversity ensures very important functions, such as: pollination, biological crop protection, maintenance of proper structure and fertility of soil, protection against erosion, nutrient cycling, control of water flow. The aim of the paper was the assessment of the influence of different agricultural systems on biodiversity using various indicators. The study showed that organic system was more conducive in maintaining biodiversity of flora, earthworms and ground invertebrates than conventional and integrated system. Developing of organic system may increase the level of different ecosystem services necessary for human (pollination, soil structure, biological control, cultural values, human health). Cultivation of perennial energy crops: willow and miscanthus negatively influenced earthworms abundance which may affects the productive and retention functions of soil.
