Study on Factors Affecting Desertification by Soil Nutrient Analyzer

At present, the research of desertified soil nutrients mainly focuses on the differences in nutrients of desertification soils, the effects of plant succession on soil nutrients and soil erosion, and the effects of human interventions on desertification soil nutrients. The preliminary understanding of the process of desertification through soil nutrient fastness testers. Soil nutrients change law. However, there are also some issues that need further study:

The lack of research on soil nutrient fastness indicators for soil nutrients and other physical and chemical properties in the process of desertification directly affects the classification, grading, and judgment of desertified soil, which in turn influences the development of reasonable desertification control measures. It is necessary to strengthen the investigation of the physical and chemical properties of soil nutrients such as desertification types and desertification levels, and formulate diagnostic indicators for quantifying the nature of desertified soil.

Wind erosion and water erosion are important driving forces affecting desertification and nutrient changes. However, the current research on soil erosion and erosion in desertification areas is incomplete. Most of the studies are only calculations and simulations of erosion modulus, and there is a lack of earth biophysical chemistry with nutrient conversion. The interrelationship of the processes; the numerical simulation of the soil nutrient velocity measurement instrument on the sand movement is also in its infancy, and the established model is far from the actual situation.

Various numerical models of desertified soil nutrients have been simulated and transformed, a mature regional climate, vegetation, hydrological conditions and production management measures have been established. Based on this, some more complex integrated models have been established, but these model parameters have complex features. It is hard to find. Therefore, the soil nutrient fastness tester analyzes soil moisture and nutrients and combines the plant growth model, mechanism, and desertification process with more practical significance for desertification control.
