Growers and advisers have a better understanding of the benefits of deep ripping and in particular depth of deep ripping required to optimise crop yield & profit. They also better understand where the cost is worthwhile (rainfall zones, soil types) and very importantly how long the benefit lasts for in a CTF system.
Growers and advisers will be able to assess the likely cost-benefit to them/their clients of deep ripping.
