Answer:
The answer is D. Limited farmland encourages intensive farming with intercropping to produce high yields.
Explanation:
When practicing agriculture of any form, be it crop or animal agriculture, the resources used are always limited and will not be enough.
Therefore, in the scenario presented above, we see that the land to be used is limited, hence, the farmer must think of a way to maximize the use of his limited land.
The best way to do this is practice what is known as inter cropping, this strategy has the following merits:
- higher yield compared to planting just one crop.
- it serves to mitigate against risk.
- higher revenue will be generated from the sale of both crops.
Therefore it is imperative that farmers with limited land look for ways to maximize the use of the land.
