Unverferth Primary Tillage
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 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. |
