This trial was conducted to help understand if it is necessary to deep rip prior to strip-till. The yield results from this trial favored the deep ripping followed by strip-till over the strip-till. Our data averaged 0.77 T/Ha more yield in a growing season that
saw record rainfall. We feel that the deep ripping allowed for more water infiltration and savings for later use resulting in increased yields. We also feel that it is not economically feasible to deep rip every year. This trial needs to be repeated over the next few years to give us a better indication differences in a more typical growing season. When we monitored fuel usage it was still a financial advantage of R2870.4/ha to deep rip then strip- till. We will plan to repeat this trial again next growing season.
