“…Also the lack of fertilizing may cause changes in the plant association. The value of the changes depends on the management type of used and the aim of reserving (Szemán 2007b;Tasi 2007. We can conclude that the level of nutrient supply can modify the proportions of different grassland components in the grassland composition (Tasi, 2007;Kulin et al 2008).…”

“…We can affect the rate of plant species or facies, dosing these substances (Kádár et al, 2007). According to Szemán (2007), the number of grass species increases when nitrogen fertilizers are applied. According to Bánszki (1991), nitrogen fertilizers promote the propagation of Dactylis glomerata L. and Bromus inermis Leyss., as these species prefer nitrogen.…”

“…The use of large dose fertilizers results in a major decrease in the number of grassland species (Harcsa, 2009). It has also been observed that leguminous species disappear from grasslands after large doses of nitrogen (100 kgha -1 ) are applied (Bánszki 1991, Szemán 2007). Potassium and phosphorous provide favourable conditions for the spreading and survival of leguminous species (Szemán 2007;Barcsák 1978Barcsák , 2004.…”

The interactions of ecological conditions, genotypes and agrotechnical elements determine the yield quantity, quality and stability in cereal (wheat, maize) production. The applied input-level can modify the adaptive capacity of crop models to ecological conditions and resilience of agro-ecosystems. The effects of agrotechnical elements (crop rotation, fertilization, irrigation, crop protection, plant density) were studied in the long-term experiment on chernozem soil. Our scientific results proved that the high yields and good yieldstability were obtained in the input-intensive crop models, so these models had better adaptive capacity and resilience. Maize had lower ecological adaptive ability than winter wheat. The optimalization of agrotechnical elements reduces the harmful climatic effects so we can increase the resilience of cereals agro-ecosystems. The yields of wheat varied between 2 and 7 t ha -1 in extensive and 8 and 10 t ha -1 in intensive crop models and the yields of maize ranged between 2 and 11 t ha -1 and 10 and 15 t ha -1 , respectively.

Botanical changes were examined on a ten-year-old semi-natural grassland established using mixtures with high species diversity. The mixtures contained seventeen wild flowers of natural origin together with two leguminous and seven grass species or varieties. Three different mixtures were arranged in three replications. The grassland management system was non-intensive (without nutrient supply or irrigation). A survey involving cover assessment revealed nine residual species from among the twenty-six originally sown. The main question addressed in the study was whether there was any connection between the ecological properties of the habitat and the ecological needs of the residual species and it was concluded that all the residual species had similar temperature, water balance and soil requirements. It could be seen that the present plant association gave a good reflection of the results of soil analysis. This suggests that soil analysis should be carried out before sowing new species-rich grasslands in order to compile a mixture suited to the nature of the habitat.

The magnitude of Ambrosia artemisiifolia has been increasing notably in the last years, both economically and medically too. Hungary and Croatia are countries in Central Europe, where this plant occures, so dealing with this question is a principal aim. The area nearby Lake Velence is residential and resort zone as well, so as it is worth considering. We started with this issue, at the Agricultural Office of County Fejér Plant Protection and Soil Conservation Directorate Velence, the position of Ambrosia artemisiifolia in this area. Our measurements are covering the monitor of this kind of weed, the prevalance of appearence and the time pattern of it. Further more the special reason of appearance driven by field distinctivenesses, just as the possibilities of controll and the opportunities given by legal regulation.
