Answer:
Fertilisers and manures contain plant nutrients such as nitrogen, phosphorous and potassium, etc. So, when fertilisers and manures are added to the soil in the fields, then the soil gets enriched with nutrients like nitrogen, phosphorous and potassium, etc. Nutrients are replenished by certain different microorganism that are found in the soil or also by the death of certain plants such as the rhizobium plant.
