Abstract

Excerpt from the report Introduction: The importance of cobalt as a limiting factor in the nutrition of sheep and cattle in the United States has resulted in several investigations of its occurrence in the vegetation and soils in trouble areas. Much of the pertinent literature is found in foreign journals and is not readily available to those engaged in field work. Furthermore, the volume of the cobalt literature suggests the need for a summary and evaluation of those reports dealing with the cobalt content of vegetation and its relationship to soil. In this review the purpose has been to present a critical and comprehensive survey of the literature rather than a series of abstracts of individual papers.
