Managing Residue in Strip-Tillage

Dave Delhotal was surprised to hear the lengths some strip-till farmers were going to in order to successfully manage the crop residue on their acres. The farmer from northern Illinois learned some other growers were planting shorter-statured corn varieties just so they had less residue in their fields.

That hasn’t been a problem on his farm.

“I haven’t found a field of corn residue I can’t get through with the SoilWarrior,” Delhotal says. “The way it’s designed there’s nothing it won’t handle.

Even though his SoilWarrior handles whatever he throws at it, Delhotal does pay attention to residue management and not just on corn acres.

Delhotal farms with his father, raising corn, soybeans, and some alfalfa. He says they've experimented with reduced tillage since 2009 and have been exclusively zone tilling the past two seasons.

“The biggest reason we went to strip-till was for soil health,” Delhotal says. “The second reason was for fertility placement. Reducing trips across the field, fuel use, and labor were other big reasons.”SoilWarrior in corn residue

While he credits the SoilWarrior with being the best tool he’s found for residue management, there are several things Delhotal has learned about the issue from years of strip-till farming.

It starts up front
Delhotal says residue management begins with the combine. He uses a corn head that chops stalks right at the base of the plant. It spreads the stalks out evenly, which reduces residue issues. Some chopping heads fill the center of the row with stalks and leaves right where his strip is. 

Keep it even
Whether he’s dealing with cornstalks or soybean residue, Delhotal strives to get even distribution across his fields. In addition to using a chopping head on corn, he also uses a spreader on the back of his combine to scatter soybean residue evenly.

“The SoilWarrior works in any conditions, but I do these things with the residue to make it perform even better," Delhotal says. “It’s great to have a machine that will go through anything and do a good job. It's is a huge piece of the puzzle when it comes to residue management.”

Two pass system
Delhotal says the two pass approach is another key part of his residue management. He makes a pass in the fall to till the zones and clear residue from them. Winter winds and driving snow push stalks back on top of the tilled strips. The spring pass really clears the zones and allows him to precisely place fertilizer while preparing a good seed bed for the coming crop.
