2010 – mouldboard ploughed 5 ha 2012 – mouldboard ploughed a further 30 ha in the trial paddock 2012 – clay strips 150 t clay-rich subsoil/ha 2012 – combined treatments included a strip of clay spread on top of part of the 2010 mouldboard ploughing (Mouldboard 2010 + Clay) or an area of spread clay that was then inverted into the subsoil using a mouldboard plough (Clay + Mouldboard 2012). |
