CTS’s Agricultural Laboratory Proficiency (ALP) Program has added the Solvita Soil Test to its proficiency list of procedures. The new CO2-Burst Method met the necessary prerequisite that at least 12 commercial USA soil labs be using it.  Solvita is seen as filling a gap for commercial lab tests which have not included biological assessment  of soils in their test suites. Since 2007,  Dr. Robert Miller has serv

What’s the inherent yield potential of soil? How long does it take compost to alter it?  A collaboration of the Highmoor Agricultural Experiment Station and Woods End Labs utilizes two types of compost (leaves, biosolids) at 3 rates and compares soil and plant tests designed to predict nitrogen sufficiency: Solvita-CO2-burst, PSNT, 7d-Nmin, Chlorophyll and stalk-nitrate. The project is now in its 2nd year with
