Sac County land and soils

The youngest glacial landscape in Iowa — flat to gently rolling ground pocked with prairie potholes, closed depressions, and heavily tiled black soils.

Deep, poorly drained Clarion–Nicollet–Webster soils with Okoboji and Harps silty clay loams in the potholes. Organic matter runs high and drainage is the limiting factor, not fertility.

Moisture: Mesic on the knolls, wet-mesic on the side slopes, and hydric in every pothole and tile-blowout. Most fields need two moisture tiers of seed, not one.

Common CP practices in Sac County

  • CP25Rare and declining habitat — the default upland planting on lobe ground.
  • CP23Wetland restoration in restored potholes and prior-converted wetlands.
  • CP42Pollinator habitat that survives the wet-mesic swings of pothole country.
  • CP38SAFE acres targeting pheasant and waterfowl nesting cover.

When to plant in Sac County

Dormant seeding from mid-November until the ground locks up, or frost seeding in February–March, works best here — spring mud season is short and pothole ground stays too wet to drill until late May.

Biggest local challenge: Reed canarygrass in the wet edges. Plan a burndown season and use a cordgrass-heavy wet mix so natives can outcompete it.
