Why is replenishment of soil essential? Describe two natural ways of soil replenishment.
Some nutrients of the soil get depleted by growing the same crop year after year. So, replenishment of the soil is essential to keep it fit for further cultivation.
Two natural ways of soil replenishment are:
- Crop rotation, and
- Leaving the agricultural land uncultivated for one or two seasons so as to allow it to regain its fertility.
