The present paper is focused on the evaluation of efficiency of soil-conservation
technologies to reduce surface water runoff in Central Bohemia Region. In the last years, there
has been an increase in maize planting on hillslope plots due to the construction of many biogas
plants in conditions of Czech Republic. It enhances the risk of water erosion because the
occurrence of sloping lands in the Czech Republic is high. To evaluate the technologies of stand
establishment a field trial was laid out with four treatments of maize planting. The trial was laid
out on a plot with light soil and slope of around 12%. It was a multi-year trial. To measure erosion
parameters a rainfall simulator was used (measurement of surface runoff). The values obtained
in two seasons show a positive effect of the soil surface cover by organic matter when reduced
soil tillage was used. Soil loss also decreased at the same time compared to treatments with
conventional soil tillage. It was found up to six-fold reduction in surface runoff by appropriate
soil tillage technology during two seasons of measurement.
