Which type of bad inpact of fertilisers are observed on crops
Answers
Answer:
Fertilizer can destroy or increase anormally the development of some natural weeds or micro-organisms; then it can disturb the agro-ecosystems. It can also pollute underground water by the nitrates it contains.
Too much fertilizer, especially N can contribute to crops being lodged (knocked down) in bad weather
excessive use of fertilizer affects soil quality and environment, such as water pollution through runoff, causing excessive richness of nutrients in a lake or other body of water (i.e. eutriphication) and pollution of the atmosphere as gas emission (e.g N2O). Continuous and excessive applications of nitrogen fertilizers containing sulfates (e.g. ammonium sulfate and ammonium sulfate nitrate) cause and exacerbate soil acidity, particularly in humid tropical soils.
