Sažetak
My acquaintance with Marta is not a representative number of years, but this friendship is influenced on me and my professional occupation on a considerable extent. I met Marta 2005 at the international congress. Even then I was impressed with her simplicity, but also a large expertise in the scope of soil tillage. After the first, followed by a large number of meetings and mutual visits, where we exchanged ideas, but mostly I learned from her. Always motivated me, and it seems today, that its results and knowledge transfer to farmers, because it is the main goal, to improve agriculture. The quality and contribution of scientists is often measured by the number of published scientific papers, but work with Marta for me is far more, that is mutual friendship and shared love for soil tillage. One of the most important component of soil, in addition to chemical and physical, is biological component, as regards soil organisms, which are more or less responsible for his "well-vital-normal" functioning. Biological component or soil biodiversity is very important, but in the same time not well known component of the land ecosystems. Biodiversity of soil make organisms which is life cycle, fully or partially implemented or in the soil or on its surface (including harvest residues or mulch), and are responsible for the process is very important for health and fertility of the soil. Communities of soil organisms form very strong, and the linked food web, whose activity is determined by soil organisms interact and coexist with the living and dead plants and animals of soil. "Structure" soil food web is very complex and composed of the relative number of members of particular groups of organisms in the soil, and is directly dependent on the differences between agroecosystems. For example, in a healthy soil are a large number of bacteria and organisms that feed on them, but if the soil gets a large amount of pesticides, fertilizers, etc., can drastically reduce the number of beneficial organisms in favour of the pathogen. This unfavourable imbalance of soil organisms leading to disease appearance and other problems. Plants, mosses and some algae are autotrophic organisms and play a main role in primary production, or production of organic substances, using light energy, water and carbon (from CO2 from the atmosphere). Another autotrophic organisms use energy from inorganic chemical reactions. Soil fauna and most fungi, bacteria and actinomycetes are heterotrophic, which is in its energy needs depend on organic matter derived from primary production or through intermediaries (secondary and tertiary consumers). The simplest and most common way of classifying soil organisms is by their size and they are divided into three main groups, namely: microbiota, mesobiota and macrobiota.
