Reducing the flow of nutrients into Maryland waterways is a principal mission of University of Maryland Extension (UME). The Home and Garden Information Center and Maryland Master Gardeners teach residents how to fertilize plants responsibly, improve and conserve garden soil, and recycle nutrients through composting and grasscycling. Soil testing gives gardeners important information they need to make good decisions regarding soils and fertilizers.
The University of Maryland no longer has a soil testing lab. On the last page of this publication you will find a list of regional private and public soil testing labs for you to contact for information on soil testing. The University of Maryland does not endorse particular businesses and the inclusion or exclusion of specific labs does not reflect a bias. All of the listed labs can competently test soils and provide an understandable report that will include liming and fertilizing recommendations.
