The influence of agricultural activities on surface waters physico-chemical parameters in Novohradsko area
SLAVÍKOVÁ, Lucie
Agriculture is an activity that affects the landscape. The aim töf this work was to observe the quality of water in the Novohradsko area. These following water quality parameters were measured: pH, conductivity, nitrates, phosphates, sulphates, chlorides and alkalines cations. The parameters changes were analysed for the years 2005 - 2010. The values of conductivity on the upper profile Stropnice River exceed the value of 50 ?S.cm-1. The values of conductivity in the lower profile of the Stropnice River do not exceed 175 ?S.cm-1. The results confirmed that the farming has a significant influence on the water quality in the Stropnice River although it is an extensive farming.
