In the soil nutrient fast-analysis analysis, interference problems different from conventional analysis are often encountered. For example, when the potassium is measured, the conventional masking agent cannot be used because of the different pH of the extracting agent. Therefore, new masking methods and masking agents must be researched and developed. Again, conventional methods for the determination of trace elements usually need to be extracted to achieve the purpose of increasing the concentration of the test solution and reducing interference. In order to simplify the operation, the soil nutrient quick tester usually does not pass the extraction in order to improve the portability, so it is necessary to develop anti-interference ability. Stronger masking technology.
As a special instrument and portable instrument, the soil nutrient speed meter is widely used in order to reduce the cost and weight, but the filter has poor monochromatism, resulting in a large line error, and many products are linear. Errors range from 4% to 8%. The proportion of total errors in measurement is too large. At present, better instruments use interferometric or thin-film filters, or use intelligent software for error correction. The linearity error can reach 2%. Within ~3%, it basically reaches the level of grating type II spectrophotometer. In addition, in order to improve the sensitivity and stability of the violet-blue region, light sources and detectors should be optimized and light source stabilization techniques should be used.

The Superiority of Soil Nutrient Speed ​​Measuring Instrument in Soil Quick Measurement
Soil analysis plays an important role in the development and construction of modern agriculture. However, it is cumbersome for the analysis of soil in the early stage. To increase the speed of testing, it is necessary to achieve simultaneous rapid extraction of various nutrients. The combined rapid leaching must be compatible with the rapid-analysis system and must be significantly correlated with the plant's absorption of soil nutrients. In order to share technical data using routine analysis, it also needs to be significantly related to routine analysis. The soil nutrient speed meter is fast and accurate and reliable in the analysis of soil nutrients.
