Q- A farmer grows rice crop year after year in his field. He notices a gradual decrease in fertility of the field. What could be its cause?
Answer- It is absolutely right that the farmer is not only noticing that the fertility of his field has been decrease but actually the fertility has been decreased because he is growing rice crop year after year that results in loss of nutrients that are required by rice crop in the field. Now to recover fertility of the soil the farmer has to follow these three methods:
1. Mixed cropping
2. Crop rotation
3. Inter cropping
