Question

Write about the natural methods used to maintain soil fertility

Answer 1

Field fallow: In this method, the land is fallow or free for either a season or more. This ensures that the soil retains its nutrients.

Mixed cropping: This is the process of growing more crops at the same time in the same field.

Crop rotation: Growing a crop in between two similar crops.

Answer 2

$\huge\bf {Answer:}$

There are some natural methods used to maintain soil fertility -

• Field Fallow
• Mixed Cropping
• Crop rotation.

$\huge\bf {Explanation-:}$

Some lines about the natural methods to maintain soil fertility-

• Field Fallow - This is one of the natural methods of replenishing the soil fertility by leaving the land without growing any crop for one or more season.

During this time dead plants and animals get decomposed by the action of microbes in the soil and thus nutrients get added in the soil.

• Mixed Cropping - This is the process of growing two or more crops simultaneously in the field.

At first ,the crops are so chosen that they benefit each other. Such as a cereal crop like wheat is grown with a legume crop like pulse. The wheat benefits as the soil is rich in nitrogen because of the legume.

• Crop Rotation - Crop rotation is the practice of growing two different crops alternately in the same field.

This method maintains soil fertility, prevents crop diseases and pests, and ultimately gives better crop yield.
