soil degradation

Answer 2

Soil degradation is the most plausibly accounts for the reduction in corn yield

Answer: Option A

Step-by-step explanation:

Soil degradation is the phenomenon where soil loses its fertility. Soil loses its fertility over a period of time when the same crop is grown for several years in a low. This causes all the nutrients of the soil to be consumed completely and the soil is left with no nutrients to support the growth of crops.

When crops are grown, it is important for the soil to stay fertile and the fertility of soil should be replenished using fertilizers or natural ways so that the crop yield can be high.
