In addition to sowing cereals, up to three different materials can be applied in one pass with the Primera DMC depending on the model, e.g. seed and fertiliser in the single-shoot process. Different seed types can also be combined.
This means that different combinations of catch crops, e.g. legumes and grass seed, can be applied simultaneously. The legumes can be sown deeper as a nitrogen fixer. Fine seeds, such as grass, can be broadcast on the surface via the baffle plates on the GreenDrill. This principle also applies to the sowing of undersown crops! However, two different seed types plus fertiliser can also be applied in this way.
Advantages of the use of undersown crops/companion plants/catch crops:
- Greater biodiversity
- Less soil erosion
- Better protection against moisture loss
- Improved soil structure
- Improved nutrient availability
- Fewer crop protection measures
- CO₂ fixing and humus formation
- Increased photosynthesis
