| Popis: | The residues of organic matter in the soil are transformed biologically over a shorter or longer time period. In the humification process, a part of the organic decomposition products formed the dark-coloured humus. The other part of the organic matter is also decomposed by the activities of heterotrophic organisms, in which inorganic substances are produced from the organic matter. The direction and intensity of the transformation, however, depends not only on the organic material stock of the soil but also on the organisms in the soil. They are closely related to soil properties, natural fertility, environmental factors and applied agrotechnical processes. The rate and speed of humus formation and mineralization processes determines the soil organic matter stock and the set of nutrients that can be uptaken by plants during the degradation of organic matter. The transformation of alternative plant nutrient, organic matter (composts, green manure, sewage sludge, slurry etc.) is determined by the living organisms with different activities in the soil. In present publication the results of most important physical and chemical properties of 12 different soil types in eastern part of Hungary (chernozem, meadow, marsh, brown forest soil, blown sand, and solonetz) are analysed. The vegetation of involved soil types were: winter wheat, orchard, oak forest and natural grassland. There were also determined the total content (stock) of some main elements (C, N, S, P) in the soils and their ratios (C/N, C/S, N/S) were compared also. There were investigated the available nutrient content of the soils (CaCl2 solution extractable nitrate and sulfate content). Based on the results, there was also calculated the proportion of the available and the total element content of soils. |
