Join the global effort happening right now to drawdown carbon from the atmosphere to fight climate change by adding compost to your yard.  Compost helps sequester C02 from the atmosphere by nourishing your soil and plants, which fix CO2 into stable forms stored in the soil long term. Adding compost to your soil has been proven to increase carbon sequestration in soil. (Kerline, 2019) 

In the Fall we offer a Special, "Compost for Yard Health," which is a fine compost, screened to 1/2 inch that is easy to spread for topdressing your lawn, trees or garden beds. 

Yard Benefits

• Feed your perennials and trees.
• Feed your lawn where you want lush green and/or wildflowers. Cover reseeded grass to retain moisture and provide nutrients.
• Topdress your vegetables (even if there is compost in your soil already).
• Less watering needed
• Drawdown carbon from the atmosphere.
• Improve property value with more green growth and more blooms.

If 7 home owners were to spread just 1/2 inch of compost over their lawn, it would be enough to drawdown nearly one metric ton of CO2 emissions over a span of 3 years. (Ryles, 2013)

Lab Analysis - We have our compost tested at University of Maine each year for nutrients, pH, salts and C:N ratio. Additionally we test it for heavy metals (lead, nickel, cadmium, chromium, zinc, copper, and arsenic).

Plant Trials - We believe that plants don’t lie, and we know that analytical reports from laboratories won’t tell the whole story. That’s why we grow vegetables, fava beans and clover in our compost in a controlled plant. Clover and fava beans for the presence of persistent herbicides, using published bioassay protocols, and vegetables to show general vigor as they are heavy feeders.

Biology - We test the compost for communities of bacteria, fungus, protoctist and nematodes. We tend to be a bacterial dominated compost, but over the long term fungal populations establish.  Our compost is great for making compost tea.

A note on pH: Compost normally shows pH 7 to 8 if it is rich in nutrients (especially for food scrap composts). This does not mean that it is going to dramatically send your soil’s pH sky high. The high pH of compost is attributed to the initial pool of 'ready to go' soluble nutrients. After that, the pH comes down to between pH 6 to 7. The compost will continue to release nutrients as the organic matter decomposes over the season.

Heavy Metals: This graph shows metal content found in our compost and soil blend compared to state thresholds.  

PFAS: This chart shows the content of fluorinated compounds found in our compost compared to state thresholds. Note that our compost meets the criteria to be used in the state's strictest use case: compost can be used on a farm that sits over a drinking water supply and grows food where children are present.
