The basic problem confronting the dairy industry today is one of utilizing its total fluid milk production. During recent years the industry has witnessed a general decrease in per capita consumption of dairy products while per capita production has remained fairly constant and in amounts approximating the average for the past 16 years (Table 2 ). As a result the dairy industry has produced a surplus of fluid milk and manufactured dairy products. The Federal Government, under its price support program, has been the ultimate recipient of these surpluses and now possesses huge warehouse stocks. The cost to the Federal Government and to the taxpayer has been great, resulting in an intense desire by both the Federal Government and the dairy industry to take steps to alleviate this condition. The following study is undertaken with the hope that the findings from it may provide the dairy industry with information which, in some small way, may contribute a partial solution to this problem.

Die Autoren halten eine hinreichende Getreideproduktion zur Ernährungssicherung in Bangladesh für möglich. Die jetzige Produktionsplanung orientiere sich aber an einer zu engen Zielplanung (Katastrophenverhinderung) und gehe z.T. von falschen Daten aus. Ansatzpunkte für eine Integration der Getreideproduktion in einen die gesamtwirtschaftliche Struktur berücksichtigenden Entwicklungsplan. (DSE)

This book elucidates the vital but often neglected relationship between bottom soil and water quality. An understanding of this important connection is essential for maintaining water quality within optimum ranges for shrimp and fish. It is the first volume to provide information on topics from soil science essential to pond aquaculture. The impact of soil-water interactions on water quality is examined, and the volume provides important methods for enhancing the soil conditions in ponds. Detailed chapters include coverage of *soils in pond aquaculture *physical, chemical, and mineralogical properties of soil *soil nutrients *the exchange of dissolved substances between soil and water *soil organic matter, anaerobic respiration, and oxidation-reduction *sediment soil *relationships to aquatic animal production *pond bottom management and soil analyses. Bottom Soils, Sediment, and Pond Aquaculture gives students and professionals in aquaculture insight into the principles of soil science which most affect pond management and provides them with an essential and current reference
