| Tartalmi kivonat: | This study examined the impact of organic pig slurry on soil properties over three years through regular sampling on calcareous chernozem soils near the city Orosháza, in the south-eastern part of the Great Hungarian Plain (Pannonian Basin). Field plots with varying slurry application histories were assessed using soil, groundwater and plant sampling, along with laboratory analysis of the physical and chemical parameters of the soil.The results indicate that repeated slurry application markedly altered the microelement composition of the soil, in the newly established agricultural plot treated with pig slurry for the last three years zinc concentrations increased by approximately 60% and doubling sodium levels compared to control plots. The humus content steadily increased from 2.10% to 2.98%, reflecting improved soil structure and organic matter accumulation, particularly in the deeper layers. The control, untreated areas showed shallower humus layers and reduced nutrient levels. Notable changes in macronutrients emerged primarily in plots with multi-year slurry treatment, though some effects were already visible within the first year. Groundwater analyses did not reveal contamination; however, shifts in deeper soil strata underscore the need for careful timing and dosage of application.In addition to soil analysis, plant data, meteorological records, and remote sensing were used. Spectral indices effectively detected vegetation differences, especially higher biomass peaks in treated areas. These findings indicate that repeated slurry application contributes to improved soil nutrient availability and organic matter content, which are associated with enhanced soil structural properties and water retention capacity The study supports a site-specific and environmentally responsible use of organic slurry, offering practical insights for improving soil health and productivity in similar agroecological zones. © Author(s) 2026.
