There are many benefits of soil testing and formula fertilization, benefiting the country and the people. There are 100 benefits and no harm. It should be a basic national policy to formulate laws.
At present, agriculture is facing a situation of reduced arable land, tightened water resources constraints, and high fertilizer prices, but limited room for rising food prices. Solving the problems of agriculture, rural areas and farmers, and promoting the increase of farmers' income, is easy to do.
Doing a good job of soil testing and formulating fertilization and raising the level of scientific fertilization can not only stabilize production, improve efficiency, improve the quality of agricultural products, but also protect the ecological environment and promote the sustainable development of agriculture!
The benefits are mainly reflected in:
First, increase the output of soil testing and formula fertilization to increase production in three forms:
1 Fertilizer production increase: Do not increase fertilizer investment, adjust the ratio of N, P, K and trace fertilizers in chemical fertilizers, correct partial application, and increase output.
2 Lose weight and increase production: For blind investment, only relying on more production for high yield and low economic benefit for fertilization, reduce the amount of fertilizer, but also ensure the level of production and even increase production.
3 Increased fertilizer production: If the application of chemical fertilizer is small or if only one nutrient fertilizer is used, the crop yield does not reach the maximum profit. The fertilization point or the minimum nutrient in the soil has become a factor limiting the increase of crop yield. Appropriately increase the amount of fertilizer or apply a certain amount of fertilizer. The nutrient element fertilizer can greatly increase the crop yield.
Second, improve the soil fertility The soil fertility is to provide the crop with a variety of nutrients for the comprehensive ability. Formula fertilization can fertilize the soil and maintain the continuous productivity of the soil. The application of trace elements can eliminate soil barriers and overcome physiological diseases. For example, the problems of soil nutrient imbalance, such as the lack of boron in flowering rape, the lack of boron in cotton, the buds without flowers, the lack of zinc in young plants, the deficiency of zinc in white maize seedlings, and the lack of molybdenum-deposited yellow seedlings in winter wheat, can all be determined through soil testing. Formula fertilization to solve.
Third, improve product quality According to soil fertility and crop fertilizer needs to formula fertilization, not only can significantly increase crop yield, but also can significantly change the product quality. Soil testing and formula fertilization can increase the content of minerals in foods; increase the content of vitamin C, soluble sugar and other nutrients in vegetables and fruits; improve the cotton clothing, cashmere length and boll weight, and reduce the loss of buds and bells.
Fourth, improve the efficiency of resource use The chemical fertilizer we applied, under normal circumstances, nitrogen fertilizer utilization rate of 30% -45%, phosphate fertilizer is only 20 - 30%, potassium is the highest, only about 50%, the rest are volatilized Leaching, fixing and other losses. With the exception of some unavoidable factors, these losses are largely related to irrational use. According to the characteristics of different crops requiring fertilizers, the lack of supplements and supplements can only make better use of fertilizers.
V. Protection of the environment Chemical nitrogen fertilizers are lost to the natural world. After a series of chemical changes, they will produce toxic compounds with carcinogenic properties. Not only that, due to irrational application of fertilizers and lack of trace elements, resulting in poor growth of crops, resulting in reduced ability of crops to resist pests and diseases, which have forced the use of pesticides in large quantities, causing environmental pollution, ecological damage, and greatly affecting human health. The use of soil testing and fertilizer technology can minimize the loss of fertilizer resources and reduce the chance of environmental pollution.
VI.Protection of Farmers' Benefits The application of soil testing and fertilizer application is conducive to further stabilizing and standardizing the agricultural capital market, and can effectively curb the occurrence of counterfeit fertilizers and pit farmers.
