简介
Volume 47 focuses on environmental quality and biotechnology. Four articles on soil science cover the effects of acidic deposition on forested soils, transport of chemicals through soil, transport and retention of inorganics in soils, and use of surface complexation models in soil chemical systems. Two articles on crop science survey crop variety fingerprinting, and the evolution of corn. For agronomists and biotechnologists in academe, industry, and government. Annotation c. by Book News, Inc., Portland, Or.
