The study looked at soil properties in an agricultural area in eastern Croatia to understand how they vary across the region. By analyzing data from over 2400 soil samples, the researchers found that soil pH and organic matter had less variation compared to plant available phosphorus and potassium. Most samples had low organic matter levels, suggesting a need for better soil management practices. The maps created showed different levels of nutrients in the soil, which can help farmers decide where to fertilize and lime their fields. The study also found that soil properties were influenced by factors like soil type. Overall, the research highlights the importance of understanding soil variability for better land management and environmental protection.
