- It is done using a plough.
- It is done using seed drill.
3) Harvesting is the process of gathering a ripe crop from the fields.
- Traditional tool used in harvesting was sickle, modern machine used in havesting is combine harvester.
.......... is the first step to be followed before growing a crop.
-
Preparation of soil
-
Harvesting
-
Weeding
-
None of the above
A.Preparation of soil - it is bed to grow or cultivate soil.
Mulching is a process that helps in

-
Improvement of soil structure
Mulch is a protective layer of a material layered on top of soil. Mulch can be made of organic materials such as grass, straw, bark, etc. They can also be inorganic such as stones, brick pieces and plastic. Mulching prevents water evaporation from soil hence leads to moisture conservation. Thus, the correct answer is option C.
