Agronomy

The Department of Agronomy seeks to teach the study of the farm-field, its crops, and its science and management. It originally consisted of three sub-departments to do this: Soils, Farm-Crops, and Agricultural Engineering (which became its own department in 1907). Today, the department teaches crop sciences and breeding, soil sciences, meteorology, agroecology, and biotechnology.

History
The Department of Agronomy was formed in 1902. From 1917 to 1935 it was known as the Department of Farm Crops and Soils.

Corn Suitability Rating 2 Equation Updated

2015-04-15 , Miller, Gerald , Burras, C.

The equation for calculating Iowa’s Corn Suitability Ratings (CSR) was recently updated and designated Corn Suitability Rating 2 (CSR2). The updated equation provides every user an opportunity to calculate the rating for each soil map unit identified in Iowa. Corn Suitability Rating 2 remains an index to the inherent soil productivity of each kind of soil for row crop production. The index is scaled from 100, for the most productive soils, to 5 as the least productive.

Establishment and persistence of legumes on sites varying in aspect, landscape position and soil type

Most Iowa pastures display only a small variety of plant species, resulting in large seasonal and annual variations in pasture productivity. This project evaluated the causes for these variations in cool-season grass pastures and considered ways to improve diversity of legume species used for grazing.
