1. In severe drought – principle of a water pump: The re-consolidated strips provide soil contact directly in the seed furrow. In this way, capillary water reaches the seedling even in dry weather. The re-consolidation in strips ensures that your soil works as a water pump. 2. In much wetness – principle of drainage: The loose soil absorbs any rain well and stores it. Rain from heavy downpours simply soaks into the unrolled, loose areas and so soil erosion is prevented. In this case, your soil works like a drain. Even at heavy, wet soils there is enough loose soil available between the rows to cover the seed with loose soil. 3. Gaseous exchange – the lungs principle: The loose soil also enables gases to be exchanged, so that the roots can breathe.
