To provide a demonstration site to observe the effects of mouldboard ploughing vs. no cultivation on non-wetting soils and crop growth and yield.

• This large scale on-farm demonstration has shown how soil inversion with a mouldboard plough can provide wheat yield benefits on sandplain soil.
• The mouldboard ploughing reduced the soil water repellence by about a third, but moderate repellence was still present. In this trial frost affected the mouldboard plough treated area more than the untreated area which is opposite to what some growers have reported who felt that crops on mouldboard ploughed soil were less affected by frost.
• Soil type, soil moisture, crop biomass and timing of the frost event may have had an impact in 2014.
• Short-term grain yield responses to cultivation on sandplain soils are typical and the potential benefits need to be studied for several more seasons before the value of the practice can be properly assessed.
• Other deep soil cultivation practices, such as deep ripping, can also give wheat yield responses in the first year.
