This technique involves tilling the soil at depths not exceeding 15 cm, with minimal layer inversion. A satisfactory seedbed is obtained with one/two machine passes, while maintaining crop residue cover on at least 30% of the surface of the plot.
Operations can be carried out with disc harrows or other mounted, semi-mounted or towed tools equipped with working parts that are not moved hydraulically or by PTO. In viticulture, minimal tillage of the sub-row is required to break soil crusts. Furthermore, once-off tillage is required to sow essences of the grass sub-strata in the inter-row.
