How are synthetic fertilizers harmful?

But synthetic fertilizers do not just have a negative impact on farmers and soil. The world’s oceans are suffering under an increase of dead zones, areas of low oxygen levels, which cause aquatic life to suffocate and die. This process is depleting oxygen levels and causing the death of fish and other aquatic life.

What type of hazard is synthetic fertilizer?

Synthetic fertilizers increase the nitrate levels of soil. These harmful nitrites react with the hemoglobin in the blood stream to cause methaeglobinaemia, which damages the vascular and respiratory systems, causing suffocation and even death in extreme cases (when blood methaemoglobin level is 80 percent or more).

What are the harmful effects of fertilizers?

There are several harmful effects of chemical fertilizers. Some of the harm chemical fertilizers may cause include waterway pollution, chemical burn to crops, increased air pollution, acidification of the soil and mineral depletion.

Do synthetic fertilizers cause cancer?

At worst, chemical fertilizers may increase the risks of developing cancer in adults and children and adversely affecting fetal brain development.

How do synthetic fertilizers affect soil?

Synthetic fertilizer application begins the destruction of soil biodiversity by suppressing the role of nitrogen-fixing bacteria and enhancing the role of everything that feeds on nitrogen. These feeders then amplify the decomposition of organic matter and humus.

Is chemical fertilizer harmful to humans?

Chemical fertilizers are harmful if excessive quantities are used. This results in contamination of surface water via runoffs and its consequent effects. Heavy metals such as Cadmium and Lead have been found in fertilizers, which can cause disturbances in the kidneys, lungs and liver and cause cancer.

Is urea fertilizer harmful to humans?

Inorganic fertilizer in itself, is not harmful to humans. It is beneficial to human by meeting immediate nutrient needs of crops thus correcting soil nutrient deficiency.

Are artificial fertilizers good or bad?

In short, synthetic fertilizers can harm the environment because their nitrogen and phosphorous levels are often higher. Instead, bacteria and microbes in the soil are stimulated by the chemicals in synthetic fertilizer, which leads them to consume more organic matter than plants can put back into the soil.

Is fertilizer toxic to humans?

Plant fertilizers can poison people and pets if they are inhaled or accidentally ingested. Touching the fertilizer may cause skin irritation, and ingesting it may be poisonous. Nitrogen is essential for plant growth, but it can be very dangerous when present at high levels in humans.

Is NPK fertilizer harmful to humans?

Nitrates form when microorganisms break down fertilizers, decaying plants . Notwithstanding the positive effect NPK has on the soil and plants, there is a significant health effect to the soil and to humans. If humans or animals drink water high in nitrate, it may cause methemoglobinemia, an illness found infants.

Are fertilizers toxic to humans?

Are chemical fertilizers safe?

Properly applied, both organic and chemical fertilizers are safe for people, pets, plants and the planet. Test your soil to determine its nutrient needs before you fertilize. Established gardens may have a history of fertilizer use. Various nutrients, such as potassium and phosphorous, can build up in the soil.
