Black Soil

CARA’s Soil Health Lab allows producers and others access to biological and physical soil assessments, to understand what is affecting their soil health and to build a bridge for improving it based on localized and site-specific constraints.


Take a look and read the CARA SHL Sampling protocols for collecting your Soil.


Download these two forms to be submitted with your soil samples. Make two copies of each - one for your records and send the other two in a ziplock with your soil to us. 


Find out the pricing for all of your soil health assessment.
