1993
Jones, J.B. (Micro-Macro International Inc., Georgia (USA))
The developments that have occurred in the United States of America regarding farmer and grower provided soil testing and plant analysis services from the early 1990s to the present are briefly reviewed. Significant changes have occurred in terms of the type of laboratory providing these services, methodology, and instrumentation. Developing environmental implications related to soil testing and plant analysis will begin to impact the number and types of tests that will be mandated, and those who will be qualified to conduct these tests, as well as requirements for laboratory accreditation and certification. The results of a 1991 survey of soil testing and plant analysis laboratories are given.
