Soils in Ludogorie region are strongly influenced by the peculiarities of the rock base and the features of the relief, climate and vegetation. The spread of the typical carbonated and podzolized black soils standing for 39% of the total arable land is in close connection with the loam and loam-like basis, the comparatively dry climate and the presence of mainly xerophilous steppe vegetation from the North to the South. The gray and dark gray forest soils (61 %) have formed on mica schists, carbonate sandstone, etc., under the influence of hydrophilous beech vegetation which was gradually destroyed and replaced by more xerophilous plants.
Due to the forests clearing and the intensive erosion processes the gray forest soils are featured by a thin humus eluvial horizon varying from 5 to 30 cm not exceeding an average depth of 20 cm. The gray and dark-gray forest soils have good structure, admitting air and retaining moisture and quickly warming up in spring.
The soil and climatic features of the municipality favour growing of all crops typical of the moderate climate and mostly the development of grain production and technical crops. Apart from the crops listed above, the soil and climatic conditions in the area of Isperich Municipality are suitable for growing of berries and fruit trees. Traditional agricultural sectors are: grain foods growing and production, tobacco, sunflower, perennial plants, etc.
