Organizational Unit

Extension and Experiment Station Publications

It can be very challenging to locate information about individual ISU Extension publications via the library website. Quick Search will list the name of the series, but it will not list individual publications within each series. The Parks Library Reference Collection has a List of Current Series, Serial Publications (Series Publications of Agricultural Experiment Station and Cooperative Extension Service), published as of March 2004. It lists each publication from 1888-2004 (by title and publication number - and in some cases it will show an author name).

Organizational Unit

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.

Abstract

Tillage system and crop rotation systems have significant long-term effects on soil health, productivity and quality, soil carbon, and other soil physical, biological, and chemical properties. Furthermore, tillage and crop rotation control weed and soil borne diseases. There is need for a well-defined, long-term tillage and crop rotation study across the different soil types and climate conditions in the state. The objective of this study was to evaluate the long-term effects of five tillage systems and crop rotations on soil productivity and quality.
