Soil testing and formula fertilization is an important means and method for advancing the development of agriculture in the modernization and scientific process. In addition to the use of scientific instruments and other instruments, it also needs to pay attention to propaganda methods and methods so that more grass-roots farmers can understand and understand.
1, publicity
Publicity and training use modern media such as TV, Internet, radio, newspapers and periodicals, wall advertisements, etc., holding a meeting of heads of households, training sessions, distribution of clear papers, recommendation cards for fertilization, questionnaires on the use of formula fertilizers, etc., promotion of soil testing and fertilization The effectiveness of improving efficiency, improving quality, increasing production, protecting the environment, and sustaining development has changed the long-term practice of farmer blindness and uncertainty.
2, important significance
2.1 The application of soil testing and formula fertilization technology will greatly influence the growth of fertilizer demand.
A large number of survey results show that China's current excess fertilizer and inadequate coexistence, excessive fertigation in some areas is serious. The promotion of soil testing and formula fertilization technology is to solve these problems and make the fertilization tend to be reasonable, which will inevitably reduce the growth of fertilizer demand. According to calculations, if the nitrogen fertilizers in areas with excess wheat, corn, and rice are reduced, they will just be able to meet the demand for nitrogen fertilizers in the original areas.
2.2 Soil Testing and Formula Fertilizing Technology Extension Will Change the Ratio of Nitrogen, Phosphorus and Potassium Fertilizers
From the perspective of farmers' fertilization status, the most serious problem of excess fertilizer is nitrogen fertilizer, followed by phosphate fertilizer. Therefore, the application of soil testing and formula fertilization has different effects on N, P and K, which may reduce the proportion of nitrogen fertilizer and appropriately increase the proportion of potash fertilizer. The promotion of soil testing and formula fertilization technology may change China's chemical fertilizer supply system.
For a long time, our country has taken the chemical synthetic fertilizer supply system. With the promotion of formula fertilization technology, the proportion of mixed compound fertilizer will gradually increase, and the supply of basic fertilizer will develop rapidly. The promotion of soil testing and formula fertilization technology will promote the reform of China's fertilizer marketing system. The soil testing and formulating fertilization project will formulate the fertilization formula for the main crops at the county level through the determination of large-scale soil nutrients and field experiments, and publish it to the public. This will promote the construction of agrochemical service system for fertilizer companies. Fertilizer marketing will be combined from simple sales of fertilizers to fertilizer sales and technical services.
