African cabbage is an open leaf cabbage used for cover crops and grazing. African cabbage has deep growing tap roots that break up hardpans and open up heavy soils. A C:N ratio of 14-25:1 means that stem/root material will not deteriorate until spring. African cabbage is excellent at sequestering nutrients and releasing them in the next growing season. An excellent fertility builder, African cabbage sequesters sulphur and is capable of releasing phosphorous once thought tightly held by the soil colloid.
