Abstract: Assessing the abundance and deficiency of soil nutrient elements holds critical referential significance for guiding agricultural production, improving the planting structure, and implementing location-specific scientific fertilization. This study investigated Tangyi Town, a typical agricultural area in Liaocheng City. First, this study tested 15 nutrient indicators in 84 topsoil samples from representative cultivated land. Second, using the geographic information system (GIS) and geostatistical analysis, this study revealed the spatial distribution patterns of various geochemical elements. Third, this study conducted single-indicator and comprehensive assessments of soil nutrient geochemistry. The results show that the soils from cultivated land in Tangyi Town exhibited relatively abundant to abundant P and CaO contents, and moderate to relatively abundant K₂O content. Their S content displayed overall relatively abundant to a higher level and a non-uniform distribution, with local excess observed. Additionally, they manifested relatively deficient N and organic matter contents and generally moderate trace element content. This study identified a Se-rich soil area of approximately 2.98 km², representing about 4.76% of the total cultivated land area, with Se content ranging from 0.49×10^-6 to 2.03×10^-6. The comprehensive geochemical grades of soil nutrients in the study area are predominantly of grades Ⅱ (relatively abundant) and Ⅲ (moderate), covering areas of 54.11% and 40.47%, respectively, indicating favorable conditions for agricultural production. This study ascertained the soil nutrient status of cultivated land in the study area and identified Se-rich land resources, providing fundamental geochemical data for guiding the development and utilization of land resources and developing distinctive agriculture.
