We often say that the soil testing and formula application meter can guide the farmers to formulate fertilization. It is of great significance to further promote soil testing and formula fertilization techniques and guide accurate pesticide application in various regions. However, the method of soil testing and fertilizer application to guide farmers in formulating fertilization is How was it? However, there is no detailed introduction, so this article will introduce in detail the two aspects of soil testing and formula application of fertilizer to guide farmers in formula fertilization: 1, using soil testing and fertilizer application instrument to measure soil, to obtain soil fertilizer content data Soil testing and fertilizer application of soil fertilizer indicators are generally ammonium nitrogen, available phosphorus, available potassium, organic matter. This is the most demanding and most common type of fertilizer in the crop production process. In the determination process, farmers only need to follow the instructions for soil testing and formula application to complete soil testing independently, which is very simple and convenient. 2. According to the testing results of the soil testing and formula fertilizing instrument to guide the fertilization After understanding the actual nutrient data in the soil, it is necessary to guide the fertilization according to the results. In this link, it is also divided into two steps. The first is to check the amount of fertilizer required for a crop of 100 kilograms. Since different crops require different amounts of fertilizer, we need to check the data to determine the amount of fertilizer required for common crops. These data can be obtained through the Internet or professional agricultural technical data. The second is to calculate the amount of fertilizer applied according to the calculation formula. In this way, after testing, querying, and calculating through the soil testing and formulating fertilizer application, the results of formula fertilization can be obtained and the farmers can be guided to complete the formula fertilization operation. By understanding the process of metering and formulating fertilisers for farmers, we will find that the soil testing formulation technology is actually not that complicated. One of the most important scientific instruments in the promotion and implementation of formula fertilization technology. Compared to other heating methods, inverter pool heat pumps are generally more energy-efficient and cost-effective in the long run with advanced technology. They can also operate in a wider range of temperatures and can heat water more gradually and evenly, which can lead to a more comfortable swimming experience. UWO offers a wide range of high-efficient inverter pool heat pumps for above ground pools.
