The Soils of Botevgrad Valley

Abstract

The paper deals with Botegrad valley soil cover, properties, conditions and vegetation. The soil cover in the Botevgrad region is characterized by considerable diversity in the ravine valleys of the Bebresh River and its tributaries. Alluvial and Diluvial soils occur in the middle of the region in lowest parts. Gray forest soils developed in the Pre-Balkans and the northern slopes of the Balkan Mountains and Light Gray forest soils (Pseudopozolic soils) are spread there too. The most fertile soils are Dark gray forest soils but only in limited area. Shallow soils (Lithosols), are widely spread over reddish-brown quaternary materials, characterized by the presence of many skeletal particles. The soil cover on the slopes is eroded, cut by deep ditches, ravines and valleys. Main part of the land in the valley is cultivated. Arable lands for cultivation and pastures are about 68.4%, other 22% are used for mainly for forestry. Settlements, industrial zones and other infrastructure occupy 9% of the valley.

Hydrogeological conditions in the Botevgrad Kettle

“…Допълнителни изследвания, с регионална и локална геоложка насоченост, продължават да се извършват и след това (Gerdjikov et al, 2015(Gerdjikov et al, , 2023Kostova et al, 2017;Dotseva et al, 2018;Hristov, 2020;Krastanov, 2022;Vasileva et al, 2023).…”

Spatial variation of the physicochemical properties of soils from the Botevgrad Valley

“…Покрай притоците на реките в котловината са разпространени и Алувиалните почви които заемат 1,3% или около 197 ha. Селищата заемат около 9% от територията на котловината (Bachvarova et al, 2005;Hristov, 2020). В настоящото изследване са проучени основно обработваеми земи заети с Алувиални почви (тук са включени и Алувино-ливадните почви), Делувиалните почви, Сивите горски почви, както и Ливадно-блатните почви.…”
