PIERRE – Due to this year’s drought, the South Dakota Natural Resources Conservation Service has allowed an “area-wide variance” for minimum residue requirements on highly erodible lands (HEL).
The variance applies to all counties in South Dakota except Roberts, if eligibility requirements are met.
The area-wide variance would be available for any untilled HEL fields where residue levels are less than required by the conservation plans due to drought or because residue has been harvested for forage (silage baled, grazed).
With the following exceptions, the variance would not apply to HEL fields that have been tilled and have inadequate residue levels since it is expected that tillage activities be reduced or eliminated in an attempt to ensure planned residue levels are met.
Exceptions-variance would also apply to tilled HEL fields if:
• A cover crop or fall crop was planted immediately after fall tillage.
• The only tillage was due to spring application of anhydrous ammonia (with a narrow or low disturbance shank on 30-inch or wider spacings.)
Again, the variance will only apply if minimum residue levels identified in the HEL compliance plan are not met. HEL fields with adequate residue levels would be considered actively applying the conservation plan and would not need a variance.
