Which of the following is NOT a benefit of cover crops?

Increasing immediate crop yield is not commonly considered a benefit of cover crops. Cover crops are primarily used to improve the soil health, prevent erosion, and suppress weeds, but their impact on immediate crop yield is not direct.

The primary function of cover crops is to enhance soil structure and fertility, which leads to better long-term yields. While they can contribute to higher yields in subsequent growing seasons due to improved soil conditions, this is generally not realized in the immediate growing season when cover crops are planted. Instead, cover crops often grow during fallow periods and provide benefits that build up over time rather than offering a quick boost to yield in the current crop cycle.

In summary, while cover crops serve essential roles in building soil health and preventing erosion and weeds, their direct contribution to immediate yields is not one of their primary benefits, making this choice the correct one in the context of the question.
