Soil penetration resistance as a function of depth for deep strip tillage bed with no traffic (DST-BED), deep strip tillage traffic lane (DST-TRA), conventional tillage no traffic lane (CT-NTV), and conventional tillage traffic lane (CT-TRA) in a Rhodic Kandiudox. If confidence intervals do not overlap, the differences are significant (p ≤ 0.15).
