Webinar - Soil Testing for Fertility Decisions & the Role of Organic Matter in Nitrogen Budgets

February 27, 2018 - 7:30pm to 8:30pm
Anywhere, MA


Presenter: Derek Christianson, Brix Bounty Farm in Dartmouth, MA


At the heart of the organic movement is a continued effort to sustain and regenerate our natural resources.  In this webinar we'll discuss the role of soil testing for making informed fertility decisions on organic farms and gardens.  We'll review the role of soil mineralization and organic matter, including "ENR" (Estimated Nitrogen Release), as you develop a Nitrogen Budget for your fields this year.

Presenter Derek Christianson farms at Brix Bounty Farm in Dartmouth, Massachusetts and has been farming in the Northeast for the past sixteen seasons. Brix Bounty Farm focuses on investing in our natural capital (soils) and human capital (agricultural skills and knowledge) to create sustainable sources of original wealth.  Their vegetables are marketed "hyper-locally" (currently within 5 miles of the farm) through a community supported agriculture (CSA) program, the downtown New Bedford Farmers’ Market, and a roadside stand.  Founded in 2008, Brix Bounty Farm aims to produce and promote the production of nutrient dense foods, using sustainable growing methods which focus on improving soil health for long-term agricultural viability.  Central to this mission are efforts to improve food security through community projects which increase knowledge and awareness of sustainable production techniques on farms and in backyard and community gardens.  Brix Bounty works with local non-profits and community groups to bridge the connection between soil, diet, and health.

Derek currently serves as a project consultant for the Dartmouth YMCA – Sharing the Harvest Community Farm, is a member Dartmouth’s Agricultural Commission, and is on the Bionutrient Food Association board.  He is a former NOFA/Mass board member.
