Misunderstanding 2: Since there are elements such as nitrogen, phosphorus and potassium in nature, there is no need to apply fertilizer. The nutrients in the natural world are not comprehensive, and it is not completely required by plants. If planted on natural land, one season of cultivation may consume decades of nutrient accumulation. Therefore, the application of chemical fertilizers is a necessary means to supplement nutrients in the soil.
Myth #3: Organic agriculture does not use fertilizers, especially fertilizers. There is no recognized and strict definition of organic agriculture. Organic farming also uses fertilizers, mainly using natural organic fertilizers. In fact, natural minerals are chemically processed. Most of the impurities such as heavy metals have been discharged with the waste residue. The content of harmful substances is greatly reduced. Chemical fertilizers are much more pure than natural minerals and have less harm to the environment.
Misunderstanding 4: Fertilizer and organic fertilizer have the same nutrients. Organic fertilizer should be used completely. If only organic fertilizer is used, it is difficult to meet the comprehensive and sufficient nutrient demand of crops. It is difficult to achieve high yield, high quality, or increase the area of ​​cultivated land. . In addition, the ratio of nitrogen, phosphorus and potassium in organic fertilizers varies greatly. It is difficult to achieve balanced fertilization requirements only with face fertilizers. For example, corn is only applied with organic fertilizer. To meet nitrogen requirements, phosphorus nutrients should exceed the demand for corn. 5 times, and fertilizer is the most convenient supplementary nutrient measure for balanced fertilization. The combination of organic fertilizer and fertilizer is more effective.
Myth 5: Organic agriculture protects the environment and wildlife. Conventional agriculture has a great impact on the environment. Whether it is organic agriculture or party regulation agriculture, the correct and effective use of fertilizers will not pose a threat to the environment, and the high yield of conventional agriculture makes us limited. There is enough food on the land. If all depends on organic agriculture, the world's land can't feed the world's population. This requires a large area of ​​cultivated land, which will have a greater impact on the environment and wildlife.
Myth 6: Organic foods are safer, healthier, and of better quality There is no definitive evidence in the world that the quality of organic and conventional foods is different. Even the World Organic Foods Association and responsible organic food producers have never claimed the quality of organic foods. Higher than regular food. It is recognized that proper application of chemical fertilizers can improve crop quality.
Misunderstanding 7: Fertilizer losses pollute rivers, oceans, and cause eutrophication. Although leaching of chemical fertilizers can cause water pollution, there are many factors in water pollution, and fertilizer is not the main factor. If the timing of fertilization and the amount of NPK applied are controlled during chemical fertilizer application, and scientific fertilization is used, the loss of fertilizer can be easily controlled.
Misunderstanding 8: Without fertilizer, it can also feed the world population. If there is no fertilizer, the world will cut 1/3 of the grain; all forests, wild animal sanctuary and grassland must be used as cultivated land; fertilizer industry is improving agricultural output, quality of agricultural products. And the people's living standards have played an important role. China's fertilizer production and use departments have an obligation to actively promote the role of chemical fertilizers, to eliminate people's negative impression of chemical fertilizers; at the same time, we should also vigorously carry out scientific fertilization and agrochemical services, guide farmers to scientific fertilization, and minimize the impact of chemical fertilizers on the environment. .
