With the renewed current emphasis on agricultural production efficiency and environmental quality, the technology of soil and plant analysis has taken on even greater importance. Several states now require soil testing as part of their nutrient management programs. Soil testing and plant analysis are important components of the Food Security Act and under consideration as safeguards for the new Clean Water Act. The Council on Soil Testing and Plant Analysis, established in 1969, promotes soil testing and plant analysis, including efficient use of nutrient resources, maximizing profits, and encouraging proper soil management and environmental protection. Compiled by the Council in response to the growing need for information about soil testing and plant analysis laboratories, Soil and Plant Analysis Laboratory Registry for the United States and Canada, Second Edition provides up-to-date information about public and private laboratory services, including:
