Why is the role of soil fertiliser detectors in soil testing and formulating fertilization so important?
Soil testing and formula fertilization is an advanced agricultural technology recommended by the UN Food and Agriculture Organization of China (FAO). At present, China is using the soil fertilizer tester to promote this scientific fertilization technology. The key to soil testing and formula fertilization is soil testing. It is based on soil testing to determine the fertilization plan based on the crop's fertilizer requirements, soil fertility, and fertilizer effects. Therefore, the soil fertilizer tester is used as a soil testing specialty. The importance of the instrument is self-evident.
According to the principles of soil testing and formula fertilization, we can know that its main content has three aspects, the first is soil testing, that is, the use of soil fertilizer detector to test the soil fertility; second is to understand the recharging characteristics of crops, such as rice Corn and other corn-based crops are mainly starch and protein-producing. Such crops require more nitrogen, followed by phosphorus and potassium. Potatoes, sweet potatoes, and taro and other crops promote the underground root carbohydrates. And the accumulation and synthesis of starch, the demand for phosphorus, potassium is larger, followed by nitrogen; this shows that different crops are different for the type and demand of fertilizer. The third is to clarify the fertilizer effect so that scientific fertilizers can be applied.
These three important factors are indispensable, among which soil testing is the most critical, because different types of fertilizers are used in different lands, the farming methods are different, the crops are different, and the soil fertility is not the same. , it can be said that there is no experience can be copied, so only use the soil fertiliser detector can be determined after determination, and the final fertilization process, the soil fertilizer analyzer measured soil data is often an important reference for fertilization, It is also an important prerequisite for scientific fertilization. This is also an important reason why soil fertilizer testers play an increasingly important role in soil testing and fertilizer application. It can be said that the development of soil testing and fertilizer application techniques will require continuous improvement in soil fertilizer testing. The detection level of the instrument can accurately understand the relevant conditions of the soil in a relatively short period of time.
Sodium Carbonate is an inorganic compound with a molecular formula of Na2CO3 and a molecular weight of 105.99. It is also called soda ash, but it is classified as salt, not alkali. Also known as soda or soda ash in international trade. It is an important inorganic chemical raw material, mainly used in the production of flat glass, glass products and ceramic glaze. It is also widely used in household washing, acid neutralization and food processing.
