Long-term trials have a twofold role in life sciences, acting as both live laboratories and public collections. Long-term trials are not simply scientific curios or the honoured relics of a museum, but highly valuable live ecological models that can never be replaced or restarted if once terminated or suspended. These trials provide valuable and dynamic databases for solving scientific problems. The present paper is intended to give a brief summary of the crop production aspects of long-term trials.

Privately Owned

In the United States, private ownership of land is not a new idea, yet the federal government retains title to roughly a quarter of the nation's land, including national parks, forests, and wildlife refuges. Managing these properties is expensive and contentious, and few management decisions escape criticism. Some observers, however, argue that such criticism is largely misdirected. The fundamental problem, in their view, is collective ownership and its solution is privatization. A free market, they claim, directs privately owned resources to their most productive uses, and privatizing public lands would create a free market in their services. This timely study critically examines these issues, arguing that there is no sense of "productivity" for which it is true that greater productivity is both desirable and a likely consequence of privatizing public lands or "marketizing" their management. Lehmann's discussion is self-contained, with background chapters on federal lands and management agencies, economics, and ethics, and will interest philosophers as well as public policy analysts.
