Soil is the loose upper layer of the Earth's crust. Its chemical, physical and biological properties make it essential for the functioning of flora and fauna. It was formed as a result of pedogenetic factors and processes and it consists of water, air, organic matter and mineral particles, mostly aluminium, silicon, iron, carbon, oxygen and nitrogen. In nature, there are different types of soil that are classified according to common properties that are morphologically visible and measurable such as colour, texture and structure. In Croatia, soil is divided into 4 departments which are then divided into classes and classes are divided into types. The departments are based on water quality and wetting method and therefore there are automorphic, hydromorphic, holomorphic and subaquatic soils. Monitoring the condition of the land is based on the analysis of soil and it is prescribed by regulations. The quality as well as the requirements for the use of land must be quantitatively described, i.e. measurable. Therefore, soil quality is based on the analysis of soil samples with the purpose of determining individual quality indicators. Soil quality depends primarily on chemical indicators such as pH value, humus, the percentage of nitrogen, phosphorus, potassium, physiologically active lime and hydrolytic acidity. Soil sampling was carried out at 24 locations in Varaždin County and pHH2O value, pHKCl value, humus, total nitrogen (N), phosphorus (V) oxide (P2O5), potassium oxide (K2O), total carbonates and hydrolytic acidity were analysed.
