Martin's Farm Compost and Mulch
341 Plain Road, Greenfield, MA 01301 -- (413) 774-5631
A Family Business
Martin's Farm, a local family-owned business in Greenfield, MA, has been producing top quality compost and mulch since 1981. Our customers in Western Massachusetts are using our organic compost, along with our other products, with great success.

Our compost is made up of leaves, manures, grass, recycled food wastes, cardboard and paper. With these organic wastes come many beneficial organisms that thrive in the shredded and mixed material. We are always monitoring the temperature, moisture, and oxygen levels to achieve the best growing environment for these micro-organisms.
We are open Monday to Friday: 8:00 - 4:00, year-round. In April, May and June we are also open Saturdays from 8:00 to 1:00. Other months we are open Saturdays by appointment only. Call ahead (413) 774-5631

The Composting Process
The composting process takes about three months to transform the leaves, manures, grass, recycled food wastes, cardboard and paper into rich, dark compost (Black Gold). The compost is matured for another month or so, then screened and stockpiled, or sold.
The 'screening process' screens out materials that did not break down enough; foreign material, and wood chips. Screening down to 3/8 of an inch, the resulting compost is light, fluffy, and easy to handle. This relatively quick three to four month process results in capturing more of the nitrogen and other naturally occurring nutrients, as well as a high percentage of organic matter which help grow healthy and happy plants in our customers' gardens.

You can bring your truck to our farm and we will load it for you or we can deliver it in our trucks.

We test each windrow of compost to be sure it meets our standards. These test results are available to our customers upon request.
