Erosion danger of soil blocks with selected crops and recommendation of suitable cultivation against erosion
JIRSOVÁ, Monika
This thesis deals with different types of soil degradation under the conditions in the Czech Republic. The first part is focused on the evaluation of the causes and course of degradation of soils in the present time. Among the most serious degradation factors may be included the following: pedocompaction, dehumification, land appropriation, bad infiltration, water and wind erosion. In the Czech Republic, only water erosion alone threatens 42% of all agricultural land. In the thesis organisational, technical and agrotechnical anti-erosion control measures are summarised. Their utilisation, efficiency and sophistication are also described. In the next part of the thesis there are six specific land blocks in the same farm in South Bohemia presented. Each of these blocks has a different acreage, the average slope, the crops cultivated and different representation of strongly threatened and moderately erosion-threatened vulnerable areas. The thesis evaluates the number of plants per 1 sq. m, the condition and density of the growth due to the erosive threat to all of these localities.
