The study looked at soil nutrients in different parts of the Tianshan Mountains. They found that soil in the western sections had more nutrients than in the eastern section. The top layer of soil had more organic matter, nitrogen, phosphorus, and potassium than deeper layers. Soil in the western parts was more fertile due to better vegetation cover, while the eastern parts had lower fertility. It's important to protect the soil from overgrazing and avoid disturbing the land to prevent erosion.
