Solution
Reason : 1 Mark
Description : 1 Mark each
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:
(I) Crop rotation : The main reason farmers rotate their crops is because each crop has specific nutrient requirements and if a farmer were to repetitively plant the same crop on the same field it would deplete the soil of the nutrients required to grow that crop.
(ii) Leaving the agricultural land uncultivated for one or two seasons so as to allow it to regain its fertility.
