The study analyzed soil nutrient levels in Huimin county to understand how they vary over time and space. Results showed that nitrogen and phosphorus levels were high, while potassium levels were balanced since 1985. Three types of spatial variability were identified: exchangeable potassium had a specific pattern, total nitrogen increased with distance, and Olsen-P had no clear spatial relationship. Changes in soil nutrient distribution were observed compared to 1984. The balance of soil nutrients plays a crucial role in determining their spatial and temporal variability.
