What problems can fertilizer and pesticides cause?
Fertilizers and pesticides use has led to the problem of air, water and soil pollution. The nitrous oxide (N2O) produced by microbial action on inorganic fertilizers in soil causes depletion of stratospheric ozone layer, which serve as shield against harmful UV-rays emanating from the sun.
What is the main problem caused by pesticides?
The main problem caused by the use of pesticides is that their residues persist in water and other components of the environment as they are not easily degraded in the environment.
What are the challenges faced in modern agriculture?
Cope with climate change, soil erosion and biodiversity loss. Satisfy consumers’ changing tastes and expectations. Meet rising demand for more food of higher quality. Invest in farm productivity.
What are the fertilizer problems in agriculture?
Fertilizers provide crops with essential nutrients like nitrogen, so that the crops grow bigger, faster, and produce more food. However, applying too much fertilizer can be a problem because it leads to the release of greenhouse gases and eutrophication.
What are the negative effects of fertilizers and pesticides on the environment?
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 do pesticides affect agriculture?
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.
What are the problems with pesticide use?
The chemicals can bioaccumulate in the body over time. Exposure effects can range from mild skin irritation to birth defects, tumors, genetic changes, blood and nerve disorders, endocrine disruption, coma or death. Developmental effects have been associated with pesticides.
What are some of the problems that have resulted from the modern farming techniques?

What are the disadvantages of fertilizers?
Fertilizers have the following disadvantages:
- They are expensive.
- The ingredients in the fertilizers are toxic to the skin and respiratory system.
- Excessive use of fertilizers damages the plants and reduces soil fertility.
- Leaching occurs and the fertilizers reach the rivers causing eutrophication.
What are fertilizer related problems?
consumption increased exponentially throughout the world, causes serious environmental problems. Fertilization may affect the accumulation of heavy metals in soil and plant system. Plants absorb the fertilizers through the soil, they can enter the food chain. Thus, fertilization leads to water, soil and air pollution.
How are fertilizers harmful to the environment?
When the excess nutrients from all the fertilizer we use runs off into our waterways, they cause algae blooms sometimes big enough to make waterways impassable. When the algae die, they sink to the bottom and decompose in a process that removes oxygen from the water.
What are the effects of overuse of fertilizers and pesticides?
Overuse of chemical fertilizers and pesticides have effects on the soil organisms that are similar to human overuse of antibiotics. Indiscriminate use of chemicals might work for a few years, but after awhile, there aren’t enough beneficial soil organisms to hold onto the nutrients”.
What are the harmful chemicals used in chemical fertilizers?
So, those are list of chemicals that resulting harmful effects of using chemical fertilizers and pesticides, there are other chemicals and some of them are below : Aldrin/Dieldrin. Atrazine. Chlordane. Chlordecone. Endosulfan. Endrin (Endrin aldehyde) Heptachlor/Heptachlor Epoxide.
What are the environmental effects of pesticides?
Environmental Effects As basically the function of pesticide is to kill pest by poisoning them the side effect of it might not far from it. It is reported that the usage of chemical fertilizer (read more : iron used in plant for growth and fertilizer) and pesticide contaminated and poison the soil, water, turf, and other vegetation.
How do chemical fertilizers affect the environment?
The largest effect facing the use of chemical fertilizer’s is ground water contamination. Nitrogen fertilizers breakdown into nitrates and mixed in water through soil. Because it is water-soluble and can remain in ground water for decades, the addition of more nitrogen over the year has an effect.
