SOIL ANALYSIS

Colorado Analytical analyzes all types of soil samples for evaluation of contamination levels as well as agronomic parameters for plant growth suitability.  Methods references are from the American Society of Agronomy (ASA), American Association of State Highway & Transportation Officials (AASHTO), American Society of Testing and Materials (ASTM), United States Department of Agriculture (USDA) and Environmental Protection Agency (EPA). Turn around time will vary depending on the project, but is normally 1-2 weeks.  Please call for a quote.

Colorado Analytical offers a number of test packages for the evaluation of topsoil quality and greenhouse suitability. Nutrient soil packages come complete with warnings about possible problems, as well as fertilizer and organic amendment recommendations.  These test packages are ideal for all types of growers including landscapers and homeowners. Greenhouse soil nutrient test reports include a general interpretation of each value for most greenhouse crops.  A 12:1 Spurway extract analysis is utilized for soil-less media samples.
