Is an innovative advancement in cover crop cultivation. Unlike conventional oil radish, it produces a very thick taproot which can drill through compacted soil. It dies off in the winter, leaving deep voids which allow the soil to warm up quickly in the spring. Since bitter lupin tends not to thrive on soils with high pH levels, it has been replaced with the Deeptill radish in the Rigol DT, SolaRigol DT and BetaMaxx DT mixes. This variety has no nematode resistance to Heterodera schachtii.
