Question

Name three natural methods of manuring. Describe one of them in detail.

Answer 1

The three natural methods of manuring are -

• Field fallow
• Crop rotation
• Mixed cropping

Crop rotation - In crop rotation a different crop is grown every year. This is done because different crops require different nutrients in different quantities which allows soil to remain fertile. For example: corn which requires a lots of nitrogen is grown one year and then in the next year a leguminous plant like pea is grown as it restores nitrogen content in the soil.
