Adverse impacts of fertilizers are mainly caused by their excessive and inefficient use. This leads to nutrient losses to the environment and other adverse impacts, such as drinking water contamination and eutrophication of freshwater systems and coastal zones.
How is fertilizer harmful to the environment?
To grow, plants require nitrogen compounds from the soil, which can be produced naturally or be provided by fertilizers. However, applying excessive amounts of fertilizer leads to the release of harmful greenhouse gases into the atmosphere and the eutrophication of our waterways.

Effects of chemical fertilizers on soil are great and irreversible. Long-term use of chemical fertilizer can change the soil pH, upset beneficial microbial ecosystems, increase pests, and even contribute to the release of greenhouse gases.
How does fertilizers cause global warming?
Chemical reactions. Its production is energy-intensive, requiring the burning of fossil fuels. After farmers apply these synthetic fertilisers to crops, chains of chemical reactions generate nitrous oxide, or N2O, a greenhouse gas.
Why are fertilizers harmful to soil?
Chemical fertiliser overuse can contribute to soil acidification and soil crust, thereby reducing the content of organic matter, humus content, beneficial species, stunting plant growth, altering the pH of the soil, growing pests, and even leading to the release of greenhouse gases.
What are the negative effects of inorganic fertilizers?
Accordingly, overuse of inorganic fertilizers has caused soil, air, and water pollutions through nutrient leaching, destruction of soil physical characteristics, accumulation of toxic chemicals in water bodies, and so on , as well as causing severe environmental problems and loss of biodiversity.
How are fertilizers and pesticides harmful to the environment?
Impact on environment
Pesticides can contaminate soil, water, turf, and other vegetation. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants.

|It is slowly absorbed by the plants.||It is easily absorbed by the plants.|
|It provides a lot of humus to the soil.||It does not provide any humus to the soil.|
What are the disadvantages in using chemical fertilizers Class 9?
(i)Chemical fertilizers provide minerals which dissolve in water and soon after these are available to plants. But these may not retain in the soil for long. They may escape from the soil and pollute ground water, lakes and rivers. … (iii)The continuous use of chemical fertilizers has led to degradation of soil health.
What are the effects of fertilizers and pesticides?
A significant portion of fertilizer and pesticide applied to the soil runs off into surface water or leaches into ground water. Spraying of pesticides had lead to ecological damage like human toxic effects, cancer and organ damage from breathing and ingesting pesticides.
