Vegetables in crop rotations improve wheat yields
The benefits of crop rotation is well known to most farmers, such as breaking disease cycles and alleviating farming risk. Wheat farmers in the Southern Cape and Swartland, however, the choice of crops to include in rotation programmes is fairly limited, and often involves only canola, barley or feed crops such as lucerne.
An article by Farmer's Weekly explores farmers that have adopted a rather unconventional crop rotation programme by including cauliflower and broccoli in their rotation system. The Western Cape Department of Agriculture has also included, amongst others, brassica species (such as broccoli) in their cover crop trails as it shows benefits to soil structure and nutrients.
