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

Grasses and legumes can contribute to an efficient agriculture in two ways: First, they contribute indirectly to income by increasing or maintaining yields of other crops over time; second, they have a direct value as a feed in the production of livestock. Farmers generally are aware of the importance of forage as an integral part of the farm organization on many soils. Although they recognize the need for growing more forage, many farmers have problems of utilization.

Three basic sets of relationships determine the forage utilization system which is most profitable for an individual farmer or economically most desirable from the standpoint of society. These relationships are: (1) the rate at which forage substitutes for other feeds in the livestock ration and the rate at which forage substitutes for grain in the crop rotation, (2) capital and labor requirements, and (3) risk and uncertainty.
