However, excessive use of chemical fertilizers has led to several issues such as serious
soil degradation
, nitrogen leaching, soil compaction, reduction in soil organic matter, and loss of soil carbon.
What are the effects of fertilizers 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.
What are the effects of fertilizer?
Though chemical fertilizers
increase crop production
; their overuse has hardened the soil, decreased fertility, strengthened pesticides, polluted air and water, and released greenhouse gases, thereby bringing hazards to human health and environment as well.

contaminate water with an overabundance of phosphates and nitrates
, making it unsafe for consumption. Oxidized nitrogen, a byproduct of synthetic fertilizers, also increases smog, which may be related to higher incidence of respiratory illness and asthma.

The excessive use of fertilisers changes the chemical nature of soil and makes the soil less fertile
. 2)The excessive use of fertilisers causes water pollution in ponds,lakes and rivers.
How do the chemical fertilizers cause pollution?
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. The use of chemical fertilizers in Turkey is lower than developed and many developing countries.
How can we prevent negative effects of fertilizers?
The efficiency of fertilizer nitrogen can be increased and losses reduced, by matching supply with
crop demand
, optimizing split application schemes, changing the form to suit the conditions, and use of slow-release fertilizers and inhibitors.
Can you fertilize too much?
Applying too much fertilizer to your lawn will cause the nitrogen and salt levels in the soil to increase rapidly, which can damage or even kill the grass. When this happens, it is known as “
fertilizer
burn” and looks like yellow and brown strips or patches of dead grass.
What happens when too much fertilizer is used?
Excess fertilizer
alters the soil by creating too high of a salt concentration
, and this can hurt beneficial soil microorganisms. Over- fertilization can lead to sudden plant growth with an insufficient root system to supply adequate water and nutrients to the plant. … Low pH soil is acid and high pH is alkaline.
What are the qualities of a good fertilizers?
- Free-flowing (easily applied)
- Consistent in particle size with smooth and hard granules.
- Easily spread – ensuring even distribution patterns.
- Quickly dissolve when in contact with moist soil or water (avoid run-off)
- Free from contaminants and additives.
What are the benefits of using natural fertilizers?
Organic fertilizers
improve the soil
.
Organic materials and fertilizers improve the soil texture, allowing it to hold water longer, and increase the bacterial and fungal activity in the soil. So, they not only assist your plants, they help the soil.
What are the disadvantages of natural fertilizers?
- Not All Products Are Created Equally. Not all products are created equally and many organic products produce inconsistent results. …
- Nutrient Levels Are Low. The level of nutrients present in organic fertilizer is often low. …
- DIY Compost is a Complicated Procedure.
What are 3 problems with pesticides?
After countless studies, pesticides have been linked to
cancer, Alzheimer’s Disease, ADHD, and even birth defects
. Pesticides also have the potential to harm the nervous system, the reproductive system, and the endocrine system.
What is the good effects of using pesticides?
Pesticides
help conserve the environment
.
They enable farmers to produce more crops per unit area with less tillage, thus reducing deforestation, conserving natural resources and curbing soil erosion. Pesticides are also critical for the control of invasive species and noxious weeds.
