The condition of agricultural soils in Primorje-Gorski Kotar County, Croatia

Abstract

In the context of sustainability and the use of natural resources, it has been often shown that agricultural soils do not reach their productive function to their full potential. The ability of the soil to provide plants with appropriate growing conditions is reduced due to soil degradation. Documenting soil conditions aimed at determining soil quality indicators in relation to soil management enables to identify the type and location of degradation in order to suggest corrective measures to farmers for the soil fertility improvement. Since the basis for the successful agricultural production is appropriate soil quality from one side, and the soil quality improvement, monitoring and protection are priority according to the current legal acts, the new European Soil Strategy for 2030 and the Soil Act planned for 2023 from another side, the soil testing laboratory of the Center for Agriculture and Rural Development of Primorje-Gorski Kotar County (PGKC) conducted the initial studies in 2019. Soil samples from the agricultural field in PGKC were tested using fast methods for following parameters: soil pH, total CaCO3, nitrate content, content of plant available phosphorus, potassium and magnesium, total calcium, aggregate stability and electrical conductivity. The test results idnicated the relative condition of the soil at different locations and in different crops. In addition, the results served as a basis for the sustainable soil management measures suggestion to the farmers in PGKC.
