Pedogenetical processes characteristic to the Pereschiv catchment - Tutova Rolling Hills

Abstract

The soil cover patterns from the studied area emerged from the action of the climatic conditions, local distribution of the vegetation cover but also a slight elevation ratio induced by the relief. According to the soil map of the Pereschiv catchment, they identified 13 soil types, which belong to 7 classes. At first glance it is observed the prevalence of cernisols which occupy 40.62% of the territory (9450 ha), luvisols (25.07%, 5830 ha) and protisols with slightly more than 5275 ha (22.67%). The soils formed under the anthropic influence (anthrosols) occupy 2196 ha (9.44%). On small areas the hydrisols (203 ha, 0.88%), salsodisols (129 ha, 0.55%) and pelisols (76 ha, 0.33%) may occur.
The main pedogenetical processes resulting in the pedogenetical horizons formation are the bioaccumulation, argillisation, illuviation, carbonatation and decarbonatation, gleysation, surface-water gleysation, salinisation, alkalization and the vertic processes etc.
The improper human activity, mainly the up and down hill farming and inadequate road network resulted in a significant soil and land degradation especially through the development of soil erosion, gulling and to a lesser extend of landslides all with a negative effect on soil cover by destroying the soil horizons, humus removal, soil fertility loss .
