Examine the table for com yields in a farmland area over the course of several years. When corn is not in its growing season, farmers often cover the
crop field with a different species to prevent erosion or soil degradation.
Based on the data, what likely impacted the com growth over the three years shown here?
The presence of the rye grass increased the corn yield by decreasing competition with the weed species and preventing erosion.
The increased rainfall provided larger corn yields over the three years in the study.
The rotation of the crop with soybeans provided extra nutrients for the soil, increasing corn yields.
The lack of cover crop decreased competition for the corn, which increased its yields.
