【 摘 要 】

The erosion impact on the spatial variability of selected soil properties was picked for the purpose of the research. The chosen locality is situated close to Křenovice (Vyškov district). Sites with soil type chernozem are exploited as arable land almost everywhere in this region. The agricultural production, however, has had staggering impact during last 80 years and has caused many degradation changes of soil properties of chernozems. This work aims to point out the water erosion impact on the spatial variability of total nitrogen, total organic carbon and C/N ratio, at steep grounds with no soil protection from erosion on loess parent material.
