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).

Abstract

Farmers are faced with many decisions in managing corn and soybeans as new technologies are introduced, such as Bt corn hybrids, new pesticides, and land rolling equipment. Land rolling is the practice of pulling a large, heavy roller across soybean fields to push down rocks, smooth the surface of the field, and help break up residue. The purpose is to protect harvest equipment that could be vulnerable to rocks and corn roots. Yields are expected to improve by creating a more uniform harvest. As problems with corn rootworm resistance to Bt corn continue to be found in Iowa, it is important to research methods to manage this pest. It also is important for farmers to adopt tillage practices that not only maximize profits, but also conserve the soil. The objective of these trials was to investigate what affect various corn and soybean management practices would have on grain yield.
