Mastering the soil nutrients and their changing laws is of great significance for improving soil fertility efficiency and fertilization effects. The soil nutrient rapid measuring instrument is an important measuring instrument for modern farmers and scientific researchers to understand soil nutrients. It can quickly detect It extracts all kinds of nutrients in the soil, and plays an important role in soil nutrient research, cultivated land quality improvement, and soil testing and formula fertilization. So do you know the principle of soil nutrient tachometer ? What is the working principle of the soil nutrient tachometer?
The working principle of the soil nutrient rapid tester is that when a certain extractant is used to extract soil, fertilizer or crop plants, effective nutrients enter the solution, and the nutrients in the solution can react with the specific color developer to generate colored substances to make the solution appear Color, the depth of the solution color is positively correlated with the nutrient content, and obeys Lambert-Beer law. Namely: E=K×C×L where E: extinction degree, K: extinction coefficient, C: solution concentration, L: solution thickness. From the above formula, C=E/KL, set the concentration of the solution to be tested as C, then when K and L are the same, C=EB2B/EB1B*C where E/E can be measured from the inside of the instrument. C is the concentration of the standard solution. After the C data, the instrument can automatically calculate and display the C value.
The soil nutrient rapid tester not only provides rapid detection of soil nutrients, multiple channels work at the same time, can detect multiple samples at one time, and the powerful functional software also facilitates nutrient analysis. The built-in crop expert fertilization system can be used for more than one hundred Calculate the recommended fertilization amount based on the target output of national agriculture, fruit trees, and cash crops, and scientifically guide agricultural production based on the fertilization formula. Therefore, the soil nutrient rapid measuring instrument not only simplifies the detection process, but also facilitates the implementation of soil testing and formula fertilization projects, and plays an important technical support role in further promoting agricultural weight loss and efficiency.
