Question

crop rotation is a method of soil conservation because ______.
a. the land produces more than one type of crop
b. it requires plowing and tilling that reduces soil compaction
c. it does not use the same parcel of land in sequential seasons
d. it avoids the depletion of soil nutrients

please select the best answer from the choices provided

○ a
○ b
○ c
○ d

Explanation:

Crop rotation involves growing different crops in a sequence on the same land. Different crops have different nutrient requirements. For example, legumes (like beans) can fix nitrogen in the soil. By rotating crops, the soil is not depleted of specific nutrients as each crop type takes up different nutrients and some can replenish certain nutrients. Option a just states that more than one crop is produced but doesn't address soil conservation. Option b: Plowing and tilling can actually lead to soil erosion in some cases and is not the main reason for crop rotation being a soil - conservation method. Option c is incorrect as the same parcel of land is used but with different crops in sequence.

Answer:

D. it avoids the depletion of soil nutrients
