Concerning the effect of a large repeated ripping number, which was the specific objective of this experiment, the author shows that the increasing frequency of ripping did not induce either negative nor positive soil or crop major changes. Although the technique of this experiment was not exactly reproducing the possible effects of a large repeated ripping number performed with normal frequencies, and it is difficult to imagine such a technique, these results are in favour of not modifying the usual interval between successive ripping as used at present in Romania. Some new and promising data were obtained in this experiment concerning the aggregate-size distribution of soil layer loosened by deep ripping. Not without importance is the fact that earlier results on deep ripping effects under various soil and/or soil-water regime conditions, as well as on causes of deep ripping positive effects affecting crop yields and economic and energy outputs, were confirmed.
