Ultra-shallow tillage is focused on a working depth of 2 cm to 3 cm, so only the seed slot level is cultivated. Healthy soil with a natural tilth structure and optimum pore distribution with no harmful compaction allows the crop to develop strong and deep roots. Shallow cultivation conserves the soil structure stabilised by plant roots and soil organisms in the deeper soil layers. It also causes less disturbance to soil life habitat, as there is much less deep movement of the soil.
