In the development of agriculture, the abuse of chemical fertilizers will inevitably cause environmental pollution and cause great waste. Today, in order to increase the output of agricultural products, reduce waste, and increase economic efficiency, it is necessary to conduct targeted fertilization. Imperative. Therefore, soil testing and formula fertilization are important measures for the modern development of agriculture. How should farmers implement soil testing and formula fertilization? Soil testing, formula fertilization is technically strong, and the cost of testing is high.] For farmers, the main focus is on fertilization. The soil testing and formulation are done by agricultural technology departments. It also does not rule out the possibility that some regions need farmers' own recipes and soil testing. Specifically,
First, farmers should go to the local agricultural technology department to apply for testing and formula fertilization. The time should be selected after the summer harvest or autumn harvest, but not at other times. The agricultural technology department measures the soil to obtain the basic information of the soil fertility capacity, and the agricultural technology department determines the target yield according to the situation of the local land's annual output, and specifies the specific amount and structure of fertilization. The agricultural technicians recommend fertilization varieties and Application period and method. At present, there are three kinds of soil testing and formula fertilization models implemented in Jiangsu: First, there is a full range of services in qualified areas, and agricultural technical departments measure, match, produce, and guide the implementation of one-stop services;
The second is to measure the soil by the agricultural technology department, and then hand it over to the manufacturer for the production of special fertilizers, which are then used to guide the farmers;
Third, in unqualified areas, the technical guidance of the agricultural technology department will guide the distribution of fertilization advice cards. The farmers will use their own fertilizer to fertilize. He said that no matter which service method is adopted, it is impossible for every farmer to complete the soil testing and fertilizer application. The cost of testing a soil needs several hundred yuan, which is not economical for farmers, and farmers have to apply for testing. Soil, it is best to choose contiguous planted and area representative plots as well, in general, soil testing to 1000 acres as a unit (select 1-2 points), in fact, in different regions, different places The cultivation of different crops on the block requires the fertilizer nutrients to be different from each other. The “small formula†fertilizers are the best for the “nutrition cateringâ€. However, the manufacturers often cannot achieve the farmers' wishes. Therefore, after the farmer tests soil, It is best to buy compound fertilizers first, and then according to the data measured by the soil testing, what elements are missing and what elements will be deployed. For some farmers who have purchased soil testers, training in earth-boring and soil testing techniques must be conducted before they can be implemented.
