Question
Explain how fertilisers are different from manure.
✓
Answer
Differences between fertilisers and manure:
| Fertiliser | Manure |
| Fertilisers are commercially available plant nutrients | Manure is a natural substance prepared by the decomposition of animal excreta and plant wastes |
| They can be organic or inorganic in nature. | Manure is known to have a large quantity of organic materials and very little amount of plant nutrients. |
| They ensure healthy growth and development of plants by providing them with nitrogen, phosphorus, potassium, etc | They help in enriching the soil with organic matter and nutrients. |
| The addition of fertilisers to the soil requires special guidelines such as dose time, post addition precautions, etc., to be followed. | The addition of manure does not require any special guidelines. |
| A fertiliser does not provide any humus to the soil. | Manure provides humus to the soil and increases soil fertility. |
| Its excessive use causes water pollution. It cannot replenish organic matter of soil. | It protects the environment and helps in recycling farm waste. |
