Molybdenum as a constituent of several inmportant enzymes is an essential micorelement. It can be found in all kind of food naturally at low level, however, environmental pollution, from natural or anthropogenic sources, can lead to high level of the metal in plants. Our study is based on the long-term field experiments of Nagyhörcsök, where different levels of soil contamination conditions are simulated. Plant samples were collected from the experiment station to study the behaviour of elements: uptake by and transport within the plants, accumulation in different organs, phytotoxicity and effects on the quantity and quality of the crop.In this work we present the effect of molybdenum treatment on the uptake of other elements. Molybdenum is proved to be in an antagonist relationship with copper and sulphur, while molybdenum-phosphorus is a synergist interaction.However, in most of the plants we studied increasing molybdenum-treatment enhanced cadmium-uptake. We have found the most significant cadmium-accumulation in the case of pea, spinach and red beet.

The effect of extended drought conditions on soil, the unfavourable cultivation technologies and the application of chemicals have been enhancing the processes of physical and biological soil degradation, so the fertility of soil is gradually declining. The effects of two cultivation methods – traditional ploughing (TP) and conservation tillage (CT) – on the biological activity of a meadowchernozem soil were examined in a long term experiment. Different parameters of the biological activity of soil were determined. These arethe numbers of total bacteria, microscopic fungi, aerobic cellulose decomposing bacteria, as well as the activities of some important soilenzymes and CO2 production.Conservation tillage seemed to be a more favourable cultivation method for the majority of microorganisms, the activities of urease anddehydrogenase enzymes and CO2 production, compared to the traditional ploughing system. These parameters increased significantly,especially in the upper layer of conservation tillage plots. Concerning the plant cultures, the majority of microbiological parameters werehigher in the soil of vetch (Vicia sativa L.) depending on the cultivation methods, so involving the pulses to the crop-rotation seems to bevery important in this soil type.According to the ninth year’s results, the importance of conservation tillage as a means of protecting the soil biological activity in meadowchernozem (Vertisols) can be established; it was proven by microbiological investigations.
