COMPASS

Nematode resistant

COMPASS freezes off easier and faster than conventional oil radish varieties
High resistance against Beet Cyst Nematodes (Heterodera schachtii) in the upper range of resistance level 2+
Long vegetative growth with low tendency to flower
Deep and intense root penetration of soil ensures a good soil structure
No additional costs for incorporation, especially suitable for mulch drilling and direct sowing methods
Early sowing of sugar beets and maize in spring is possible because of quick soil warming caused by the thin mulch layer

Included in blends: viterra® MULCH, viterra® RÜBE, viterra® TRIO
