Deep ripping, 'deeper' deep ripping and water use efficiency
  • OBJECTIVE 1: For growers, researchers and advisers to have a better understanding of the costs and benefits of ‘deeper’ deep ripping versus standard deep ripping and in particular depth of deep ripping required to optimise crop yield and profit.
  • OBJECTIVE 2: To gain a better understanding of whether the higher cost associated with deeper ripping is matched with a corresponding yield increase taking into account the rainfall zones and the soil type.
  • OBJECTIVE 3: Assess how long the benefits of ‘deeper’ deep ripping benefit last in a CTF system.
  • OBJECTIVE 4: Enable growers and advisors on behalf of their clients, assess the cost-benefit of undertaking ‘deeper’ deep ripping.
