Both manures and fertilisers replenish soil fertility. Compare and contrast the advantages and disadvatages of using them.


Advantage of using manures:

  • It is cheap.
  • It increases the water-holding capacity of the soil.
  • The number of microbes increases in the soil.
  • The texture of the soil improves.

Advantage of using fertilisers:

  • They are portable and easy to transport.
  • They are readily absorbed by the plants.
  • They are quick in providing plant nutrients and restoring soil fertility.
  • Fertilisers improve and increase the productivity of many crops such as maize, wheat, and rice.

Disadvatages of using manures:

  • It is not easy to store and transport.
  • Manure provides less nutrient to plants in comparison to fertilizers.

Disadvantages of using fertilisers

  • Fertilisers are costly.
  • Overuse of fertilisers can change the chemical nature of the soil.
