Land adjustment evaluation in light of soil protection from erosion in Horni Stropnice

Abstract

In most areas, where land adjustments were completed, only a mild erosion threat was discoverd and planned against – erosive measures were consequently minimal in these areas. There was mostly the expulsion of maize from crop rotation, grassing or projection of a new rural road so as it interupts the slope. The land adjustment Horní Stropnice was chosen for a more detailed solution, there was a higher erosion threat discoverd by the calculation of soil deterioration. The area was split in blocks, in which soil deterioration was counted by means of Wischmeier-Smith equation for various values of factor R. Then soil deterioration after implementation of anti-erosive measures was calculated. The anti-erosive component measures were evaluated and their execution in the terrain was investigated. Results show a problem with the determination of the right value of factor R and in reality planned anti-erosive measures stay mostly unimplemented.
