Description:

This event is part of a workshop series that includes farms and homesteads from across the state. Check out NOFAmass.org/events to see if there is a similar workshop closer to you!

Our soil can sometimes seem like a strange and mysterious territory — it’s dark under there, and populated with unseen forces, like earthworms, minerals, microbes, insects, roots, fungi, and (depending on the history of the site) possibly heavy metals and other pollutants.

In this afternoon workshop, the NOFA/Mass technical support team  Laura Davis and Caro Roszell  will give a workshop with Larry Najuch, owner-operator of Namuc Farm, to learn how to test your soil for both its biological vigor and its mineral profile. 

The workshop will start with a brief introduction and tour of Namac Farm to give some site-specific context. Namac Farm is a new 7-acre organic farm with two acres in mixed vegetables selling to three markets (Haverhill, North Andover, and Andover). Larry has experience with farming and with produce sales, but is new to running his own farm. The farm is situated in a densely-populated area where the neighbors are very interested and supportive of the farm. The soil at Larrys farm should be interesting to explore, since the fields have recently been cleared from woods.

Following the tour, Caro will dig in, literally, to a patch of the farms soil and explain how to assess soil for its ability to build and store organic carbon. Soils with greater levels of carbon are more resilient to weather extremes, produce healthier crops, hold water more effectively, and can remove CO2 from the atmosphere when there are healthy plants growing there.  Participants will receive a workbook of test protocols to take home, and will learn how to assess their own soil for carbon storage for measures like earthworm count, average root depth, aggregate grade, infiltration, soil respiration, and more.

We will spend the rest of the workshop with Laura Davis, NOFA/Mass Soil Testing Technical Advisor, who will teach participants about how to interpret a soil test. We will look at the soil test results from Namac Farm's soil as an example.  Participants will learn about cation exchange capacity, pH, and soil organic matter. They will also learn about mineral levels and how to figure out how to calculate amendment application rates to address specific soil deficiencies. 

Workshop participants may bring their own soil test results (results must be from Logan Labs) to the workshop for Laura Davis and receive a follow-up email with interpretation and analysis. Soil test interpretation is $25 for NOFA/Mass members and $45 for non-members. 

At the event, workshop participants will also have the option of purchasing a soil carbon proxy test kit at cost-of-materials, so they can test their own soil and track its carbon-sequestering progress.
