Aims

To identify whether there is an advantage in using deep ripping or shallow cultivation compared to direct drill to improve the ability of crops to utilize soil water at depth.

Key messages

The use of cultivation, whether deep or shallow, in 2003, shows no advantage in increasing the grain yield. In fact there may be a penalty in the loss of soil water, particularly at the surface, if the cultivation is performed in a dry autumn, as was the case in 2003.
