The soil tester found that the soil nutrient content developed by the loess-like soil parent material was significantly higher than that of the slope product, the alluvium/lake sediment. The loess-like parent material loess layer is rich in carbonate, clay and calcium deposits, and forms carbonated cinnamon soil. Therefore, soil nutrient content is high. Alluvial mother plastids often have a gravel layer, which constitutes a barrier layer in the soil, and the texture is light soil. The parent material mostly forms cinnamon soil, so the soil nutrient content is low.
The research on soil nutrient regional differentiation is an important basic work for regional planning, ecological environment protection and regional sustainable development. The related studies of soil testers show that the dynamic changes of soil nutrients are affected by soil types, fertilization, cultivation, irrigation, altitude and climate. Changes in natural environmental conditions, changes in land-use patterns, etc. will all affect the quantity and composition of soil nutrients.
There was a significant positive correlation between soil organic matter with available nitrogen, available phosphorus and available nitrogen, soil available and available potassium, and available phosphorus with the total salt measured by the soil tester. Through the soil tester, it was shown that there was a regular increase between available P and available N, available P and available K, and between available P and total salt during soil nutrient improvement in this section. In the process of soil nutrient improvement, the contents of organic matter, available nitrogen, available phosphorus, available potassium, and total salt have an independent change.

Study on Elements Distribution of Soil-forming Parent Material by Soil Tester
Soil is the carrier of land resources and it is an open complex system that is affected and affected by many factors in the environment. At the same time, the parent material on the one hand is used as the skeleton of the soil, and on the other hand, it is the original source of the plant mineral nutrient elements. Using a soil tester to perform certain measurement and analysis, it is found that it not only directly affects the physical and chemical properties of the soil, but also the soil formation process. The nature also affects the accumulation and leaching of soil nutrients.
