Brassica campestris spp. Rapa

Purple Mammoth Tops turnips are a popular option in cover crop and forage mixtures. Their large taproot has the potential of reaching down to 1.5m – playing a significant role in alleviating compaction, aerating the soil, and improving water infiltration.


The turnip’s quick establishment and dense leaves cover the soil and effectively suppress weeds. Brassicas are known for their ability of capturing residual soil nitrogen after a crop harvest.
