Soil analysis was done in the Hajdúszoboszló region to study changes in soil properties from 1966 to 2006. Different soil types showed varying trends in pH, salinity, humus, nitrogen, phosphorus, and potassium content. pH remained stable in some soils but increased in others. Salinity decreased in all soil types, with the largest decrease in meadow solonetz soil. Humus content declined the most in chernozem meadow soil. Nitrogen content decreased in some soils but increased in others. Phosphorus and potassium content increased in all soil types, with the largest rise in meadow chernozem soil. These findings highlight the importance of soil analysis for precise fertilization to improve crop growth and yield in heterogeneous cultivated areas.
