The popularity of soil testing instrument technology is difficult to access, and farmers’ scientific and cultural qualities are generally low, which makes it difficult to popularize and apply soil testing and fertilizer application techniques. Farmers have a small scale of operation, and the economies of scale in the promotion and application of new technologies are not high, and some farmers lack. Enthusiasm; Weaknesses in the promotion of township agricultural technology, lack of expertise in the promotion of agricultural technology, and insufficient technical guidance services.
Difficulty in the promotion of soil testing instruments and formula fertilizers Tian Yi is the contradiction between the diversity of formulas and the scale of enterprise production. A new formula, from demonstration to large-scale promotion and application, requires a process, while enterprise production pursues benefits. When the sales of formula fertilizer cannot reach a certain amount, enterprises are unwilling to produce;
Second, special formula fertilizers add medium and trace elements according to the soil nutrients and crops need fertilizer characteristics, increase the cost, the price is higher than similar products in the market, in the current price competition in the fertilizer market is lack of competitive advantage;
Third, the current price fluctuations in the fertilizer market, dealers are afraid to make more orders at one time, and sometimes formula fertilizer out of stock;
Fourth, the agricultural materials market is not standardized, and a few low-degraded fertilizers have a low price impact on the market, which brings certain difficulties to the promotion of formula fertilizers. Farmers often need formula fertilizers and dealers are reluctant to sell formula fertilizers.
Fifth, there is a difference between rural consumption, urban consumption, production consumption and household consumption. For agricultural products, if dealers are not willing to sell, even the best soil testing instruments and products cannot reach consumers.
Since the implementation of the geotechnical instrument technology, the fertilization structure of farmers has been increasingly optimized, especially the promotion of special formula fertilizer, which has significantly improved the utilization rate of fertilizers. The 2011 early rice fertilizer effect correction test results showed that the application of special rice fertilizer formula not only showed a significant yield increase over conventional fertilizer application, but also increased the nitrogen fertilizer utilization rate from 30.8% to 35.2%, increased 4.4 percentage points, reduced fertilizer losses, and effectively reduced The non-point source pollution of chemical fertilizers alleviated the contradiction between the supply and demand of chemical fertilizers, promoted the steady growth of crops, effectively reduced the amount of pesticides and the number of applications, improved the quality and quality of agricultural products, and promoted the sustainable development of agriculture.
