The researchers studied soil particle-size distribution in farmland to understand its variability. They used advanced methods to analyze the data and found that soil particles have different sizes across the field. Low values of particle-size distribution caused more variability than high values. The clay, silt, and sand contents in the soil influenced the distribution differently at different depths. Multi-scale analysis showed how these properties affect soil variability. This study helps us better understand soil properties and can guide soil management practices in the area.
