Abstract

Nowadays natural watery habitats are imperilled because of human landscape-transformer processes and negative effects of climate change. Degradation time of them is 5-10 years while the regeneration time of them is 10-30 years (Szabó, 2004). Low rate of anthropogenic effects can lead to significant and fast changes in these places. In our work we examined the anthropogenic origin chemical effects in the area of Lake Nagyszéksós (Mórahalom, Hungary). On the base of the examinations we constructed soil- and water-chemical parameter maps (Nyilas et al., 2012). These maps are suitable for prove the contaminations which come from the agricultural cultivated fields for example. In this paper we show the results of the iterated examination of the north coast, one year after the first full examination of the area. We chose this coast because this was the one of the most contaminated fields in 2012. We found out, that in the last year the most contaminated zones show smaller nutrients-concentrations in this year. The causes of this are the next: (1) fast leaching, (2) fast use of nutrients in the spring vegetation period, (3) the new dose of ameliorators were not turned out. Consecutively the unapplied nutrients were measured in this year.
