Nowadays, soil nutrient testing instruments are welcomed by agricultural researchers and can help agricultural producers to complete the diagnosis of soil nutrients in a simple and efficient way. With the increase in demand for agricultural soil testing technology in rural areas, the measurement efficiency of soil nutrient testing instruments is also improving year by year, which can help more agricultural extensions to achieve rapid determination of soil nutrients and significantly improve the efficiency of soil testing, thus achieving the small goal of ”cost saving and efficiency” in agricultural production. In recent years, the uneven application of fertilizer has become one of the factors affecting the high quality growth of crops in agricultural production. When farmers apply fertilizer, they are often not good at using professional soil nutrient testers, but only rely on their past experience to allocate fertilizer, which is actually very difficult to achieve the purpose of accurate fertilization. Uneven application of fertilizer, whether too little or too much, is not conducive to crop growth. Therefore, it is still necessary to use professional instruments for soil testing and fertilization in modern agriculture.
At this stage, many farmers still believe that crops will be productive if they apply sufficient amount of fertilizer. However, this is not the case, and fertilization should follow the principle of scientific and appropriate amount. Too much fertilizer will not only damage the growth of crops, but also pollute the soil environment. For the above problems, it is necessary to use soil nutrient diagnostic instrument to strengthen the nutrient diagnosis of soil and use it as a basis to guide agricultural producers to achieve accurate fertilization.
Before, agricultural producers tend to pay more attention to nitrogen, phosphorus and potassium, as well as trace elements fertilizer application, soil nutrient detector is the current instrument for soil fertilization work, its main role is to detect the soil ammonium nitrogen, fast-acting phosphorus, effective potassium, trace elements, organic matter content, in order to help agricultural producers to develop a set of relatively reasonable fertilization program.
