Application of Soil Nutrient Analyzer in Modern Soil Nutrient Analysis

In the past 20 years, China’s economy has developed steadily and rapidly. In the process of continuous development of the planting industry, there are more data requirements for soil nutrients, so as to meet the application of fertilizers and the protection of the environment. In the course of agricultural development in the future, Demand will continue to increase. The level of soil nutrient analysis is also gradually increasing. In recent years, soil nutrients have been frequently used in the measurement and analysis of soil nutrients, and the measurement of nutrient data has become more accurate and convenient.

The rapid determination of nutrients by soil nutrient fastness testers is one of the requirements and directions for the development of soil nutrient analysis. Combined extractants can save the time required for extract preparation, especially in multi-element analyzers such as ICP and flow analysis. The ultimate goal of automating soil nutrient analysis should be the soil nutrient analysis process in which the sample does not require human intervention throughout the process from weighing to analysis data. The widely used flow analysis provides a solid foundation for the realization of this goal. It only needs to graft the automatic weighing and soil extraction equipment before flow analysis to achieve this process.

A variety of different soil nutrient analysis instruments were compared, with the most mature flow analysis, moderate cost, and rapid determination. After the automatic soil extract preparation equipment is connected with a flow analysis instrument for measuring different elements, such as a flow analyzer for measuring N and P, a flame photometer for measuring K, and an atomic absorption spectrophotometer for measuring trace elements, it should be a period of time in the future. Soil nutrient analysis automation application selection. Research and develop soil nutrient automatic extraction equipment and integrate it with the above flow analysis equipment into a set of organic soil nutrient automation analysis system, and discuss the relationship between automatic analysis data and traditional methods and soil nutrient status and plant nutrient absorption. Soil nutrient analysis automation research direction. The modernization of soil nutrient analysis still has many problems to be solved in our country. Take the combined extractant as an example, the application research results in China are still less.

In recent years, the analysis of soil nutrient by soil nutrient fastness testers has become more and more common, and it is also the main soil nutrient analysis method. Soil nutrient analysis is an important part of the basic analysis methods and methods of soil science research. Without the modernization of soil nutrient analysis, there will be no modernization of soil science. Therefore, the soil nutrient rapid measurement instrument has a very important role in the rapid determination of soil nutrient related parameters.
