Cornell Soil Health Testing

Soil health describes the capacity of a soil to be used productively without adversely affecting its future productivity, the ecosystem or the environment. Soil health emphasizes the integration of biological with chemical and physical measures of soil quality that affect farmers' profits and the environment.

The Cornell Soil Health Program Work Team has developed soil measurements to help monitor the state of soil health both in space and time. These indicators can measure soil improvement or degradation resulting from different management practices and also the long term changes in soil health under given management practices.

For more information on the Cornell Soil Health Testing program including all costs, sampling instructions, submission forms, etc. visit Cornell Soil Health web site.
