purpose is to decrease over fertilization and pollution of the Yangtze river. The world is awash with nitrogen. In agriculture, nitrogen is used as a fertiliser to increase output, but this causes one of the biggest environmental problems of our time. Nitrogen pollution has Over-fertilization also introduces excess salts to soils, which diminishes crops’ ability to take up water. This can cause drought stress even when water is readily available, damage roots, cause leaves to wilt, and eventually even kill crops.

While the chemical fertilization of crops has led to low SOC and nitrogen levels compared to organic fertilizer input (Dong et al., Reference Dong, Zhang, Wang, Dai, Sun, Qiu and Yang 2012), the levels of plant-available nitrogen from organic fertilizers are also inadequate, resulting from a slow rate of mineralization and leading to lower crop yields in fields treated with organic versus chemical fertilizers …
Excess fertilizer alters the soil by creating too high of a salt concentration, and this can hurt beneficial soil microorganisms. Over-fertilization can lead to sudden plant growth with an insufficient root system to supply adequate water and nutrients to the plant. 2017-05-03 · In a world where government agencies and agribusiness have long pursued the holy grail of maximum crop yield, Haney preaches a different message: The quest for ever-greater productivity — using fertilizers, herbicides, pesticides, and whatever other chemicals are at hand — is killing our soil and threatening our farms.

Some fertilizers also contain certain "micronutrients," such as zinc and other metals, that are necessary for plant growth. This initial revolution was the result of domestication of plants and animals to serve man’s needs and led to the generation of food production in excess of the requirements of the agricultural population.
