Maryland SSURGO Soils

Soil surveys can be used for general farm, local, and wider area planning. Onsite investigation is needed in some cases, such as soil quality assessments and FOR certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center at the following link: https://offices.sc.egov.usda.gov/locator/app?agency=nrcs (USDA Service Center) or your NRCS State Soil Scientist at the following link: https://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/?cid=nrcs142p2_053951 (NRCS State Soil Scientist).
