Impact of agro-environmental systems on soil erosion processes and soil properties on hilly landscape in Western Lithuania
The objective of this study was to evaluate the impact of different land use systems on soil erosion rates, surface evolution processes and physico-chemical properties on a moraine hilly topography in Lithuania. The soil of the experimental site is Bathihypogleyi – Eutric Albeluvisols (abe–gld–w) w...
