This paper presents the dependence between particles of various sizes present in the sediments collected from the Klusov (Slovakia) water reservoir, such as sand, silt and clay and their nutrient content. The results of physical characteristics of sediments indicate that the clay/silt fraction dominated in the reservoir sediments. Chemical analysis showed that the total nitrogen content in sediments was recorded from 0.07 % in sediment collected at the inlet to the reservoir to 0.26 % in sediment taken near to the dam. Analogously, the content of phosphorus and potassium in sediments were similar. The highest phosphorus/potassium contents (0.11/2.5%) were recorded in sediments collected near the dam. Also results showed strong linear correlation between sediment grain size fractions and total nitrogen and potassium contents. In the case of total phosphorus, very strong positive association was observed with clay particles (r = 0.81, p ? 0.05) and moderate negative relationship with sand particles (r = -0.539, p ? 0.05). The fact about preferentially attaching of nutrients to clay/silt particles with grain size less than 0.063 mm was confirmed.
