Benefits & Disadvantages of – Fertilizers and pesticides in India
Fertilizers and pesticides both have definite advantage & disadvantage associated with their use. Both types of chemical tend to increase yields, and thus make a significant contrast in food production, particularly in countries that struggle periodically with famines. On the other hand, they both contribute to erosion of soil because the chemicals wash off with the rain affected farms along with disoriented soils after each rainfall. There is also concern by authorities that usage of the pesticides poses a risk, not only to animals and plants, but to humans as well.
Positive Effects of Fertilizers
There is sure shot notion that fertilizers increase productivity of crops around the world. Use of modern fertilizers exploded after World War II. Ammonia-based fertilizers also led the process of specialization of pesticides that was being carried out in agriculture.
Farmers needed to watch out for the rotation of crops less
- Vastly expanded food production and helped starve off the world hunger,
- Modern farming, including the use of fertilizers and herbicides, could “double or triple food production” in India.
- Increased food production would also reduce the need for wild lands for agriculture, thus contributing to the better conservation of biodiversity.
Negative Effects of Pesticides and how to overcome it
The downside of fertilizers
Some portion inevitably washes into waterways along with eroded soil.
- This nonpoint source runoff occurs nationwide, and the nitrogen fertilizer finds its way into rivers, lakes and the ocean where it causes eutrophication and “dead zones” that kill aquatic life.
Eutrophication is a process whereby nitrogen feeds an algal bloom, but when the short-lived algae die, decomposing bacteria then consume most of the available oxygen, suffocating aquatic life.
- Additionally, use of artificial fertilizers in place of animal or “green” manure–cover crops plowed into the soil–eventually can deplete soils of organic matter, making them lose their ability to hold water and more subject to erosion.
According to the National Institute of Environmental Health Sciences, pesticides have as yet incompletely understood effects on humans. Most people are exposed to a certain level of pesticides. Farmers who experience routine exposure to pesticides have exhibited neurological symptoms such as headache and hand tremors. Children, in particular, may be more susceptible to negative effects resulting from pesticide exposure. Pesticide runoff can have devastating effects on non target organisms as well. For example, roundup, an extremely common herbicide used in agriculture, is highly toxic to fish and amphibians.
Still the effects are very less as compared to the humans & these pesticides are of greater help towards the increasing off the productivity of the crops that are needed for the better growth of the economy of our country. HPM India is making such pesticides, herbicides & fungicides that not only helps grows a better crop but also a better way of ensuring farmers happiness towards farming.
