For which of the following uses are forage crops NOT used?

Forage crops are primarily cultivated for livestock feed and play a significant role in agricultural systems, including benefits to soil health and crop management. One of the main benefits of forage crops is their ability to enhance soil fertility. They contribute organic matter, improve soil structure, and help maintain nutrient levels through processes such as nitrogen fixation in legumes.

When it comes to improving water drainage, forage crops can help by creating better soil structure, allowing for improved infiltration and reduced runoff. Additionally, they can lessen disease risk by enhancing biodiversity in cropping systems and promoting healthier soil microbiomes, which can reduce the incidence of certain crop diseases.

The use of forage crops to decrease soil quality stands in direct contradiction to their established benefits. In fact, they are often employed to improve rather than degrade soil conditions. Therefore, it is accurate to say that forage crops are not used to decrease soil quality, making that the correct association in this context.
