Soil in Renshou County, China was studied to understand the distribution of nutrients like nitrogen, phosphorus, and potassium. The researchers found that these nutrients varied across the area, with phosphorus and potassium showing clear patterns while nitrogen had more variability. Factors like soil group, land use, and topography influenced the distribution of these nutrients. Land use was the most important factor for nitrogen, while parent material and land use were key for phosphorus. Only parent material and soil type affected potassium levels. This information can help with better fertilizer management and land use decisions in the region.
