化肥工业是由于农业生产发展的需要而发展起来的。在农业产量水平不高的长期年代中,农作物生长所需要的养分是由土壤和一些有机废物提供的。随着世界人口的增长和人类迫切需要提高衣食水平,促使农业要不断提高产量。在这种情况下,由土壤和天然有机物提供作物养分已经不能满足需要。这就出现了用工业方法来生产提供作物养分物质的化学肥料。 Fertilizer industry is due to the development of agricultural production needs and development. In the long run of low levels of agricultural production, the nutrients needed for crop growth are provided by soil and some organic waste. With the growth of the world’s population and the urgent need of mankind to raise the level of food and clothing, it is necessary for agriculture to continuously increase its output. Under such circumstances, it is no longer sufficient to provide crop nutrients from soil and natural organic matter. This has resulted in the industrial production of chemical fertilizers that provide crop nutrients.
