5. Explain how fertilisers are different from manure.

Answer: Fertilisers are chemical substances made in factories and contain specific nutrients like nitrogen, phosphorus, and potassium. They act quickly and increase crop yield. Manure is a natural substance prepared from animal dung and plant waste. It improves soil structure and adds humus to the soil. Fertilisers provide nutrients fast, while manure improves soil fertility for a longer time.
