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).

The Department of Horticulture was originally concerned with landscaping, garden management and marketing, and fruit production and marketing. Today, it focuses on fruit and vegetable production; landscape design and installation; and golf-course design and management.

Putting greens on golf courses are the highest maintenance turfgrass that exists. Creeping bentgrass (Agrostis stolonifera L.) often is used for cool-season putting greens due to the ability of the turfgrass to tolerate a low mowing height, and provide a high density turf. Managing organic matter is necessary to maintain a high quality turfgrass at 0.125 in. height of cut and one that will drain quickly after a rain to resume play. Traditionally organic matter has been managed by a three-step process: hollow tine aerification, removal of the cores from the surface, and applications of new sand to the putting green. However, many superintendents can’t afford to buy new sand every year. Wiedenmann Turf Equipment Company offers a machine that will remove much of the organic matter from aerification cores by spinning them over screens and allowing the sand particles to fall back to the putting green surface, while collecting the organic matter in a basket for removal. The objective of this project was to compare if putting green surfaces subjected to core recycling would perform as well as traditional organic matter removal practices. This is the first year of a two-year study.
