Acta Univ. Agric. Silvic. Mendelianae Brun. 2018, 66(1), 77-87 | DOI: 10.11118/actaun201866010077
In the Czech Republic, a significant amount of agricultural landscape nutrients is swept away by surface washes and leakages to subsoil. Subsequently there is a negative influence on surface water quality, where of course also point sources of pollution participate in. Flowing surface water often becomes stagnant while the certain self-purifying processes proceed both in the flowing and stagnant waters. It can be simultaneously stated that the self-purifying process is practically uncontrollable, primarily due to the impact of many entering factors. One of the environmental and technical elements providing quality improvement of water running off a...
