An improved method to impregnate soil with paraffin was used to study tillage induced macroporosity. Macroporocity and water infiltration measurements, conducted in March, attest to the overwinter stability of macropore structure on both the chisel and Praplow tillage treatments. Water infiltration was least on the no-tillage treatment.

Compared fall chisel versus standing stubble for water infiltration at 3 dates. No difference in July following harvest, much lower infiltration with stubble in December with 5" frost depth, no difference (low infiltration) in January with 14" frost depth. For chisel tillage to be effective, chisel marks must be open to the surface, and chisel fracturing should penetrate below the frost depth. Deeper chiseling at wider spacing, or subsoiling, may be an option.
