The Iowa NRCS Soils Program provides quality soil, geographic, and resources information, products, and services to internal and external customers.

This page presents daily soil temperature analysis maps. The left hand column plots combine ISU Soil Moisture Network observations and bias corrected NWS NAM forecast model analyses to produce a higher resolution plot.

Iowa Soils. Iowa is a land of farms because of its fertile topsoil known as “the black gold of Iowa.” All soils are not the same. In fact, Iowa has about 450 different soil types. Soils scientists examine various physical properties of soil to identify the different types. One soil property is texture.

Iowa is a leading state in incorporating soil health improving conservation practices such as no-till farming, cover crops, conservation crop rotations, and conservation cover.

The following maps are county analyses of four inch depth soil temperatures across the state of Iowa from yesterday, two, and three days ago.

Typical Iowa Soils 1 Revised: 2013 Edition A. General Information There are three major types of soils in Iowa: 1. Loess: A fine-grained, unstratified accumulation of clay and silt deposited by wind (37.5%). 2. Glacial Till: Unstratified soil deposited by a glacier; consists of clay, silt, sand, gravel, and boulders (28.5%). 3.

The soil association areas of Iowa have developed from three major kinds of parent material-loess (wind-blown material), glacial till, and alluvium.

It is widely accepted that Iowa's soils are some of the richest and most productive in the world. But how and why? This article explores those rich soils, how they form, how scientists describe and classify them, and the conservation challenges they face.
