Precision tillage 2014 Thurston, NE Less bulk density = less compaction Increased Soil Porosity Decreased compaction and increased soil porosity allows for robust root growth

Precision tillage 7-8-2014 Atlantic, IA 10-12 leaf corn

2014 Atlantic, IA Less bulk density = less compaction Increased Soil Porosity Decreased compaction and increased soil porosity allows for robust root growth

Ideal seedbed preparation Data from Thrall Texas Water infiltration rates are nearly double in the strip tilled section Stiles Foundation Farm, Thrall Texas

Ideal seedbed preparation Increases water infiltration Side by side Strip Till to Conventional Till Breaking compaction increases water infiltration and surface residue retains soil moisture from evaporation This photo is from our long term cooperative site, the Irrigation Research Foundation in Eastern Colorado. This is after 2 years of Orthman strip till, and shows strip-till on the left and Conventional full width tillage on the right after back to back rain events. This picture is 10 minutes after the rain had stopped - 1.10 inches the day prior and 0.70 inch this day. Rain has soaked in and not run off like it is on the right, the conventionally tilled plots. 1tRIPr STRIP TILL CONV TILL
