Crop and soil management to trap snow and reduce spring-runoff have potential to increase soil water storage. A randomized field-design using ripped and non-ripped soil was used to test whether tillage improved water infiltration into frozen soil. Studies were conducted on annually grown spring wheat (Triticum aestivum L.) near Culbertson, Montana. Soil was a Dooley sandy loam (fineloamy, mixed Typic Argiboroll). Ripping was with a single shank at regular intervals on the contour. Soil water was measured using neutron attenuation and volumetric determinations. Final infiltration rate on frozen soil averaged 17 mm h-1 and 2 mm h-1 on ripped and non-ripped treatments, respectively. In spring, average water content of the top 1.2 m of soil, to a distance 1.5 m downslope from the rip, was 32 mm greater on ripped treatments compared to non-ripped treatments at comparable slope positions. There were no differences in wheat yield between treatments. Infiltration measurements show that soil ripping has potential to decrease water runoff.
