Like roots in a too-small container, your performance would be less than its best if you had to live and work each day in such a cramped spaces. Yields suffer when compaction keeps roots from growing freely into the subsoil for optimum nutrient and water uptake. The Zone-Builder^® subsoiler from Unverferth lets plants stretch their legs (and their roots) by opening passageways through the hardpan with minimal surface disruption. Long-term university research confirms deep-tilling with tools such as the Zone-Builder implement raise yields and income.
