A significant proportion of cropland in the U.S. is annually allocated to uses not leading to harvests including cropland pasture. Not much is known about the interaction of those physical, economic, and institutional factors affecting decisions to establish and sustain cropland pasture, a seemingly lower use of available cropland. Using county data from the 1969 Agricultural Census weighted by farm numbers, preliminary analyses of the association between the incidence of cropland pasture in Kentucky and variables such as livestock numbers, type of farm, and land tenure were developed by multiple regression. These efforts are preliminary since analyses of Census data do not generate insights into the decision-making processes resulting in using a portion of available cropland as cropland pasture. These insights, however, are integral to estimating land use changes in response to changing economic and institutional conditions.
