What is Agricultural Pollution?
Agricultural pollution is waste or emissions caused by agriculture that degrades or pollutes the environment. These contaminations come from various sources and effectsly affect numerous species.
Causes of Agricultural Pollution
1. Pesticides and Fertilizers
These are mainly nitrogen and phosphorus-based chemicals such as ammonia and nitrates which in the right amounts increase soil fertility. But in most cases, these are used in excess of what is needed and hence tend to be retained in the soil not adding to its goodness.
Time after time, ranchers utilize various pesticides to kill different bugs. These pests include insects, fungi, and other invasive species. Although they help prevent attacks and preserve plant life, many of the chemicals used are toxic to wildlife and water. Most of the time, the absorption occurs when an insecticide binds to soil particles. This can be seen as a carrier traveling from the field to the bodies of water during the rainy season or by irrigation. In combination with sedimentation, insecticides, fungicides, and herbicides flood fields into large amounts of water.
2. Dirty Water
The use of contaminated water for agricultural purposes is an important issue. Albeit a significant part of the water in created nations is perfect, this might vary extraordinarily from creating lands. Water can be polluted as a result of the dumping of industrial, agricultural or private waste into rivers, lakes or other water systems.
This can cause plants to become polluted with chemicals and harmful substances such as lead or mercury. Next, these crops are used by humans as well as to feed the animals and as a result, can harm both in a serious way.
3. Soil Erosion and Soil destruction
Profound cultivating rehearses assume a key part in soil disintegration and soil obliteration. Through agricultural activities, millions of fertile soils are being demolished, damaged, and eroded via stormwater runoffs that keep collecting as corpses in rivers, streams, lakes, oceans, or other regions of the world. Therefore, it affects water quality in various ways, for example, by polluting or agrochemical residues in the soil.
Degradation can also reduce light intrusion into the water and thus affect biodiversity, and subsequent collisions could interfere with the eating habits of aquatic fish. Soil also contributes to the formation of agricultural pollution in waterways and other land areas.
In the old days, farmers kept so many animals that their land could not support them. Cattle, sheep, pigs, chickens, and other animals were fed with natural food, supported by the waste left over from the plants. As a result, the animals played a key role in keeping the farm healthy.
To date, livestock has been raised in densely populated areas where they have been placed on unnatural food and sent to slaughterhouses regularly. As a result, they are adding to the agricultural pollution process.
5. Invesive Pests, Weeds, and Diseases
Insect pests, weeds, and diseases do not directly cause agricultural pollution. However, due to the persistent and growing number of pests, weeds, and diseases that can affect crop yields, farmers are turning to the persistent use of pesticides, herbicides, and other agricultural chemicals to combat this nightmare. As a result, increased use of these chemical products persists in destroying soil, animals, plants, water, and wildlife in terms of the severity of agricultural pollution, and as a result, gradually transforms the environment.
6. Heavy Metals
Cadmium, fluoride, radioactive substances such as uranium are often found in parent minerals where fertilizers are found. Hazardous metals such as Mercury, Lead, Arsenic, Chromium, and Nickel are identified by traces of Zinc-rich waste from the steel industry used as fertilizer. This is often removed due to the high costs involved.
7. Natural pollutants
Manures and Biosolids often contain nutrients, including nitrogen, carbon, and phosphorus. In addition, because they are processed by industry, they may have contaminants within them such as personal care products (PPCPs) and medical treatments. These products have been found in human and animal bodies and are believed to have adverse health effects on wildlife, animals, and humans. Agricultural pollution becomes even more difficult to manage these types of natural pollution.
8. Land management
Intensive land management can be important in keeping agricultural pollution at a low level. Badland management also leads to an irreversible decline in interest rates. It is therefore important for farmers to have a good understanding of how their actions can affect the environment.
Consequences of Agricultural Pollution
Since agricultural pollution is not an isolated incident, its effects are further exacerbated by water pollution and air pollution. It affects all aspects of nature and all creatures, from worms to humans. A portion of the antagonistic impacts are as follows:
- Drinking or swimming in water with a dangerous level of algal bloom causes rashes, stomach and liver, respiratory diseases, and neurological effects.
- Infants who drink water with high levels of nitrates are affected by the blue death syndrome that often kills them. Symptoms are shortness of breath and blue skin.
- The formation of dead or hypoxic areas where there is no aquatic life; Examples of the Chesapeake Bay and the Gulf of Mexico
- The poisoning from algal blooms into the food chain harms large animals such as dolphin’s seals and tortoises etc.
- Air pollution by nitrogen oxides leads to the formation of smoke due to the formation of ozone. Ozone depletion damages forests and Trees.
