Abstract

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.
