Land Use in Iowa: Dominated by Agriculture

Iowa's land use is overwhelmingly agricultural, reflecting its role as a Corn Belt powerhouse.

Land Use Breakdown (Approximate)

CategoryPercentageDescription
Arable Land (Cropland)88.7%Corn, soybeans, oats, hay; among highest in U.S.
Permanent Crops0.2%Orchards, vineyards, berries (minor).
Forest / Woodland3.5%Mostly along rivers (Mississippi, Missouri), steep slopes; not commercial timber.
Water Bodies2.0%Natural lakes (Spirit Lake, Okoboji), reservoirs (Saylorville, Coralville), rivers.
Semi-Natural / Grassland2.9%Pasture, CRP (Conservation Reserve Program) land, prairie remnants.
Built-Up (Urban/Transport)2.7%Cities (Des Moines, Cedar Rapids, Davenport), roads, farmsteads.

Key Context

  • Iowa leads U.S. in corn and soybean production.
  • Less than 0.1% native tallgrass prairie remains (once 85% of state).
  • Tile drainage extensive; nitrate runoff a major water quality issue.
  • CRP enrolls ~1.5M acres (paid to keep marginal land out of production).
