The benefits of organic fertilizer

In China's agricultural production, in order to increase the yield of crops, people will not hesitate to dump a large amount of chemical fertilizers (inorganic chemical fertilizers) into the farmland, and the use of nitrogen fertilizer, urea, and compound fertilizer composed of nitrogen, phosphorus, and potassium is increasing, and the concentration The higher. Although this has maintained a certain effect of increasing output, year after year, the consequences are extremely serious, the main performance is as follows:
So what the benefits of the organic fertilizer manufacturing process are?

First, the soil is compacted and solid, resulting in poor soil porosity and decreasing organic matter content, which has caused many biological groups to lose space for survival in the soil and ultimately reduced soil fertility.
Second, due to soil compaction, the soil's water storage capacity is decreasing, and the lack of groundwater has seriously affected agricultural production.
Third, due to the soil compaction, the biological population is reduced, and the farmers ’friends are striving to increase the yield of the land, so that the amount and concentration of chemical fertilizers continue to increase, resulting in the decreasing utilization of nitrogen, phosphorus, and potassium, only reaching 30% to 40% According to the calculation of the consumption, the loss will reach 30 billion to 40 billion yuan.
Fourth, in addition to wasting losses, a large amount of chemical fertilizers remaining in the soil continue to penetrate deep underground to form a large amount of nitrate and other compounds, causing serious pollution of groundwater, and on the other hand, it is released into the atmosphere as nitrogen oxides, making The ozone layer becomes thinner, causing ultraviolet light to affect human health and the growth of crops, and the ecological environment is severely affected.
Fifth, the use of large amounts of chemical fertilizers has reduced the quality and nutritional value of various crops. Take trace elements as an example. For half a century, the content of trace elements in some crops has dropped by about 20%, and the commodity rate of crops has declined, which seriously affects the interests of farmers and consumers and the export of crops.
In short, agricultural production cannot be at the expense of resources and the environment. It must combine high yield with high quality, low consumption with ecological security, and take the road of sustainable development of agricultural production. Otherwise, for such a long period of time, the natural ecology will be seriously unbalanced, and it will be the human beings that are damaged, and the consequences will be very serious. The use of scientific methods and the combination of organic and inorganic fertilizers to produce and process organic fertilizers using animal manure as raw materials, and nitrogen, phosphorus and potassium as auxiliary fertilizers is one of the most correct ways for modern agriculture.
