The study of soils has taken on increased importance because a rapidly expanding population is placing demands on the soil never before experi enced. This has led to an increase in land degradation. Land degradation is one of the most severe problems facing mankind. Volume 11 of Advances in Soil Science was devoted entirely to this critical area of soil science. The editors of that volume, R. Lal and B.A. Stewart, defined soil degradation as the decline in soil quality caused by its misuse by humans. They further stated that soil degradation is a major concern for at least two reasons. First, it undermines the productive capacity of an ecosystem. Second, it affects global climate through alterations in water and energy balances and disruptions in cycles of carbon, nitrogen, sulfur, and other elements. Through its impact on agricultural productivity and environment, soil deg radation leads to political and social instability, enhanced rate of deforesta tion, intensive use of marginal and fragile lands, accelerated runoff and soil erosion, pollution of natural waters, and emission of greenhouse gases into the atmosphere. In fact, soil degradation affects the very fabric of mankind."

In the past 10 years, there has been a resurgence in interest in soil management and conservation of the soil resource. With the knowledge we have accumulated in the past 100 years, there is the possibility of developing new and innovative ways of effectively managing the soil. The emphasis on sustainable agriculture requires that we understand how to utilize the soil as a viable living resource. To meet the world demand for food within the next 50 years requires a healthy and strong soil resource which can sustain production. With the dedication of the National Soil Tilth Laboratory in 1989, it was decided that one contribution the laboratory could make to agri cultural science would be to foster an exchange of information on soil management. The focus of that interchange centers on long-term soil management. If we are to fulfill the goals of sustainable agriculture, environmental quality, and feeding the world, there will have to be an increased understanding of how to effectively manage the soil. Long-term soil management requires integrated and interdisciplinary research to bring all of the information together in terms which would be applicable to all soils. To accomplish this goal a workshop is held each year, with the exchange of information focusing on a single topic within the framework of developing effective strategies for long-term soil management. With the forum to focus on an individual theme each year, the theme for the initial workshop was "Limitations to Plant Root Growth."

Winner of The 1963 National Book Award for Fiction.
The hero of J.F. Powers's comic masterpiece is Father Urban, a man of the cloth who is also a man of the world. Charming, with an expansive vision of the spiritual life and a high tolerance for moral ambiguity, Urban enjoys a national reputation as a speaker on the religious circuit and has big plans for the future. But then the provincial head of his dowdy religious order banishes him to a retreat house in the Minnesota hinterlands. Father Urban soon bounces back, carrying God's word with undaunted enthusiasm through the golf courses, fishing lodges, and backyard barbecues of his new turf. Yet even as he triumphs his tribulations mount, and in the end his greatest success proves a setback from which he cannot recover.
First published in 1962, " Morte D'Urban" has been praised by writers as various as Gore Vidal, William Gass, Mary Gordon, and Philip Roth. This beautifully observed, often hilarious tale of a most unlikely Knight of Faith is among the finest achievements of an author whose singular vision assures him a permanent place in American literature.

The Best American Catholic Short Stories captures twenty of the best short stories from thirteen American Catholic writers over the past seventy-five years. Spanning most of the twentieth century, the stories in this collection deal with many of the issues brought into the spotlight with Vatican II. One ongoing area of controversy, of course, is in the very notion of Catholic fiction. What constitutes a work as "Catholic"? This new collection, with its rich variety of themes, styles, and tones, takes an important step in answering this question. Pat Schnapp and Dan McVeigh have assembled an extraordinary sampling that is unique in its subject and scope. Major contributors include Mary Gordon, Flannery O'Connor, Ron Hansen, T. Coraghessan Boyle, and Richard Russo.
