Fertilizing operations are a very important part of agricultural production, affecting the quality, nutrition, and yield of crops. In modern agricultural production, even the most experienced agricultural workers do not dare to say that they will fertilize because of the past. In the face of the current soil environment, many of the fertilization experiences are no longer effective. The current fertilization program that is widely admired is the application of soil testing and formulated fertilizer applicators to perform soil testing and formula fertilization, that is, the use of soil testing and fertilizer applicators to test and analyze the relevant nutrients in the soil, based on the results of the tests and the crops Need fertilizer characteristics, formulate the type of fertilizer to be applied, the number of application, the application method and fertilization plan for the application period, and then apply fertilization according to the plan.
In fact, due to non-standard and unscientific fertilization effects, it has caused a lot of pressure on agricultural soils and caused many fertilization problems. The most direct effect is that fertilizers are applied more and more, but the effect of crop yield increase is not obvious. It is a decrement, but after applying the soil testing and formula application instrument, can these problems be solved? What are the fertilization problems that can be solved with the soil testing and formula fertilizing apparatus?
1. Types of scientifically selected fertilizers The main function of the soil testing formula and fertilizer application instrument is to measure soil. Through soil testing, producers can clearly know what fertilizers are missing from the soil according to the actual crops so as to help producers scientifically select fertilizer types. ,Organic fertilizers with inorganic fertilizers (fertilizers) with the application, NPK combined application, a large number of elements (nitrogen, phosphorus, potassium) with the use of trace elements in combination.
2. Scientifically determine the fertilizer dosage The soil testing and formula fertilizer application can reasonably determine the amount of fertilizer according to the soil nutrient content and the needs of the sowing crop.
3. Scientific application of fertilizers Soil testing and formula application instruments can also scientifically apply fertilizers based on the characteristics of fertilizers to ensure that crops do not suffer from fertilizer damage.
4. Scientific determination of the use of fertilizer Fertilizer meter can be used at any time to quickly detect soil nutrient conditions, and according to the crop's fertilizer requirements, soil conditions, crop harvest times scientifically determine the fertilizer application period to ensure the effect of fertilization .
The soil testing and formula application instrument has played an important role in promoting soil testing and fertilizing techniques. At the same time, it has made important contributions to improving agricultural fertilization techniques, improving fertilization effects, and improving the soil environment in agriculture. Development has laid a solid foundation.
