文摘

⬢: 20 years Oberacker field trial, comparing no-till (NT) vs mouldboard ploughing (MP).
⬢: Soil pore system and gas transport properties of NT similar as under grassland.
⬢: Little difference between topsoil and subsoil properties in NT.
⬢: Higher gas transport capability in MP than NT in topsoil, but lower in subsoil.
⬢: Important to consider the whole soil profile when evaluating tillage systems.
