Question

Crop rotation is important because:

Some plants use a lot of nitrogen.
It increases soil fertility.
Repeated planting of the same crops decreases soil quality.
All of the above.

Answer 1

The answer is all of the above.

Answer 2

Option D, All of the above

Step-by-step explanation:

Crop rotation is the process of cultivating different varieties of crop on the same farm/land based on the season. This is done in order to regulate the use of a particular nutrient from soil. When one crop (A) is harvested a certain nutrient let’s say phosphorus get used, now another crop (B) which uses nitrogen is grown, this allows the soil to replenish the lost phosphorus and make itself ready for crop A again in the next season.

Thus, crop rotation is necessary to obtain all the three option A, B and C.

Thus , option D is correct.
