Residue decomposition The Normandie evenly distributes crop residues and organic matter in the surface layer. The soil is enriched as organic matter is added by the humified residue and earth mixture. Self-seeding When the Normandie passes with a depth no more than 5 cm, it creates conditions conducive to weed emergence by encouraging soil-seed contact. Seed stock lifting is dependent on soil moisture and the choice of the roller. Once germinated, a final pass destroys weed emergence and reduces the surface seed stock by about 40%. Pest control The Normandie destroys adult pests and eggs on the surface. Slugs and insects are eliminated by either mechanical action or surface dehydration. Soil warming All seeds need balanced conditions to germinate: water, air, heat and soil. With each pass, the Normandie brings moisture from the lower layer and aerates the soil. The soil then warms in the sun. The independent disc harrow thus provides the conditions for rapid germination which in turn means good planting.
