The psamic entiatrosoil from the Husnicioara quarry, District Mehedinti that resulted from the surface extraction of the lignite has unfavourable physical and chemical features: sandy – loamy texture, light alkaline reaction, low humus content, 0.2 – 0.4 %, low supplied with phosphorus (4.5 – 29.1 ppm) low and moderate supplied with soluble potash (36.5 – 61.4 ppm), being grouped in the fifth class of favourability. This is the reason why the main goal of increasing its fertility degree is to enlarge the organic matter content.
