The Sustainability Land Management Assessment System facilitates the aim to link all aspects of selected land use to the many interacting conditions – environmental, economic and social – that together determine whether this form of land management is sustainable or likely to lead to sustainability.
The purpose of the study is to determine the impact of land use on the basic parameters of Regosols.
The study found that land use has a significant impact on soil fertility. By keeping the soil in a  crop rotation farming system, by rotation of crops of cereals and potatoes and periodically applying manure, the content of digestible forms of nitrogen and potassium has improved. In the fallow farming system – cultivation of bush crops with the introduction of manure and annual plowing of plant biomass, the content of all three macro elements – nitrogen, phosphorus and potassium – is improved. Maintaining the upper horizon of Regosols with grass sowing improves the soil texture, but reduces the content of digestible forms of nutrients.
