What fertilizer is the most hazardous?
Common Nonorganic Fertilizers
- Anydrous ammonia: Contains 82 percent nitrogen.
- Urea: Contains 46 percent nitrogen gas.
- Superphosphate: Contains nitrogen and phosphate.
- Diammonium phosphate: 18 percent nitrogen, 46 percent phosphate.
How can fertilizers harm 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 harmful effects of using excessive fertilizers?
Use of fertilizers and nutrients is one way to supply achieve this. The presence of heavy metals affects the plant growth. Excess use of fertilizers may lead to heavy metal accumulation, eutrophication and accumulation of phosphate and nitrate. Excessive phosphorus is potential threat to water quality.

What are the advantages and disadvantages of fertilizers Class 8?
1)They provide quick replenishment of plant nutrients in the soil and restores soil fertility. 2)They are easily absorbed by the plants. 3)They are easy to transport,store and handle because they come in bags. 4)The use of fertilisers has helped the farmers to get better yields of crops such as wheat,maize,rice.
What are fertilizers for Class 8?
Answer: Fertilisers are the nutrient rich chemical substances that are added to the soil to increase the fertility of the soil. Use of fertilisers increases the fertility of the soil and results in better yields of food crops when added in required amount to the soil.
