There are eight misunderstandings in the use of chemical fertilizers
Misunderstanding 1: Fertilizer is a man-made chemical product. Applying chemical fertilizer is harmful to the environment, wildlife and human being. Fertilizer is actually a substance that plants can absorb. It is also called “plant nutritionâ€. The nitrogen, phosphorus, potassium, sulfur, and other nutrients in fertilizers are the same as those found in our bodies and in foods. Fertilizers are also non-toxic. Myth #2: Since there are elements such as nitrogen, phosphorus, and potassium in the natural world, there is no need to use chemical fertilizers. The nutrients in the natural world are not comprehensive or necessary for plants. If planted on natural land, a season of cultivation may consume decades of nutrient accumulation. Therefore, the application of chemical fertilizers is an essential means to supplement nutrients in the soil. Myth 3: Organic agriculture does not use fertilizers, especially chemical fertilizers Organic agriculture has not yet had a generally accepted and rigorous definition. Organic agriculture also uses fertilizers, mainly natural organic fertilizers. In fact, natural minerals have undergone chemical processing, and most of the impurities such as heavy metals have been discharged along with the waste residue. The content of harmful substances has been greatly reduced. Chemical fertilizers are much cleaner than natural minerals, and they are less harmful to the environment. Misunderstanding 4: Fertilizer and organic fertilizer have the same nutrients and organic fertilizer should be used completely. If only organic fertilizer is used, it is difficult to meet the comprehensive and sufficient nutrient requirements of crops, and it is difficult to achieve high yields and high quality of crops, or large amounts of arable land are needed. . In addition, the ratio of N, P, and K in organic fertilizers varies greatly. It is difficult to achieve balanced fertilization by using only surface-fertilizers. For example, if corn only uses organic fertilizers, it must meet the requirements of nitrogen, and the phosphorus nutrients exceed the demand for corn. 5 times, and fertilizer is the easiest nutrient supplement to achieve balanced fertilization. The use of organic fertilizers and chemical fertilizers works better. 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. Correct and effective use of fertilizer will not pose a threat to the environment. The high yield of conventional agriculture has limited us. If there is sufficient food on the land, and if it depends entirely on organic agriculture, the world’s land will not be able to feed the world’s population. This will require extensive land reclamation and will have a greater impact on the environment and wildlife. Myth #6: Organic foods are safer, healthier, and of better quality There is currently no definite evidence in the world that the quality of organic and conventional foods is different. Even the Organic Food Association of the World and the responsible organic food producers have never declared organic food quality. Higher than regular food. It is generally accepted that the correct application of chemical fertilizers can improve crop quality. Misunderstanding 7: Losses of chemical fertilizers contaminate rivers, oceans, and cause eutrophication Although the loss of chemical fertilizers can cause water pollution, there are many factors of water pollution. Fertilizer is not the main factor. If the application of chemical fertilizers, control the timing of fertilization and the amount of N, P and K, and adopt scientific methods of fertilization, the loss of chemical fertilizers can be easily controlled. Misconception 8: There is no chemical fertilizer, but also can feed the world's population If there is no fertilizer, the world will reduce production of 1/3 of the food; all forests, wildlife conservation areas, grassland, etc. must be used as arable land; Fertilizer industry in improving agricultural output, quality of agricultural products The people’s living standards played an important role. China's fertilizer production and use departments have the obligation to actively promote the role of chemical fertilizers and eliminate people's negative impressions of chemical fertilizers. At the same time, they should also vigorously develop scientific fertilization and agrochemical services to guide farmers in scientific fertilization and minimize the impact of chemical fertilizers on the environment. .
