Vermont Compost Company

Also known as: Vermont Compost

A potting-soil and compost company founded in 1992 by Karl Hammer in Montpelier, Vermont. Built on a chicken-driven composting model — hundreds of laying hens turn and aerate the compost windrows, producing eggs as a byproduct. Vermont Compost's Fort Vee, Compost Plus, and Fort Light potting mixes are the reference growing media for serious organic seed-starting in the U.S. Northeast.

Why this listing

Substrate-builder in the most literal sense — Vermont Compost makes [[mushroom-substrate|growing substrate]]. The chicken-integrated compost system is one of the most-cited examples of small-scale animal-and-plant integration in the U.S. organic-agriculture movement, and the resulting Fort Vee potting mix is the substrate that thousands of Northeast vegetable seedlings are started in every spring.

Practical

  • Chicken-driven composting — laying hens turn the windrows, eat fly larvae and weed seeds, deposit manure, and lay eggs. The compost windrow is the chicken’s pasture-substrate.
  • Product lines — Fort Vee (premium potting mix for transplants and containers), Compost Plus (raised-bed amendment), Fort Light (lighter mix for plug trays), bulk compost.
  • Inputs — locally-sourced food-waste, manure from regional farms, hay, and minerals; the operation is, in significant part, a Montpelier-area waste-stream-to-substrate transformation.

Cultural

Karl Hammer is a fixture of the Vermont [[organic-agriculture|organic-farming]] community and a fierce advocate for compost as living-microbial-community rather than as inert NPK delivery. The chicken-driven model has been studied and partially replicated by other regional compost operations; few have stayed with it at full scale. Hammer’s talks and Vermont Compost site visits are a regular pilgrimage for new market gardeners.
