Soil Health Database

Thanks to the development of the database of North Coast vineyard soils, winegrape growers can receive custom soil health reports based on lab test results.

The report contains four main sections:


An overall soil health score calculated as the average of three primary indicators (soil organic matter, potential carbon mineralization, and water stable aggregate).


The score and individual interpretation of the three primary indicators.


A measured value for some additional soil tests that can be useful to further characterize carbon and nitrogen dynamics.


General recommendations of management practices tailored to California vineyard soils which can be adopted to address specific components of your vineyards soil health.

With funding from USDA-NRCS, the North Coast Soil Hub embarked on a project to create a regionally-derived soil health scoring system for North Coast vineyards, similar to the Cornell Soil Health Scoring System.

Members of the Soil Hub gathered over 300 vineyard soil samples to analyze the impacts of management decisions on soil health and identify meaningful indicators of soil health.

Through partnering with scientists at Soil Health Institute and Oregon State University, the team developed a soil health database and performed over 65 soil health assessments throughout the region.
