write some disadvantages of fertilizers
Answers
Answer:
Disadvantages of fertilisers:
They get washed away by water easily and cause pollution.
They harm the microbes present in soil.
They reduce soil fertility.
They are expensive.
They provide only short term benefits.
They change the nature of soil, making it either too acidic or too alkaline.
Disadvantages of using artificial fertilisers:
Crops grow better, but so do weeds. Therefore herbicide sprays are required too.
Better quality plants attract insects so pesticides may be needed.
Excess nitrogen from fertilisers gets into water supplies, causing fish to die.
Chemicals need to be used safely. In poorer countries in particular, farmers can
damage their health by applying fertilisers, pesticides and herbicides incorrectly.
Artificial fertilisers, applied without organic additions, do not improve soil structure
