Answer 2

Advantages of using manure are as follows.
1.they add organic content to the soil and thus its good for our health.
2.natural fertility of the soil is retained.
3.no harmful effect on the environment.
4.wastes are utilized for good purpose.
Disadvantages of using manure are as follows.
1.Bulky in nature and slow output
2.had to be used in large quantity.
Advamtages of using fertilizers are as follows.

It increases crop yield and improves poor quality land.

Manure improves soil texture, recycles nitrogen and introduces essential bacteria.

Pasture is improved so animals fatten up quicker.

Once marshland is drained, fertilisers can help reclaim that land for pasture

Crops grow faster – particularly when hybrid seeds are used.

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.
