One of the great challenges of sustainable agriculture is the sourcing of adequate and affordable organic (carbon based) resources that can be used on-farm for the production of food and feed. Utilizing composts, manures, mulches, and other organic inputs from the farm is a challenge on its own, and the production of each often requires its own input of materials. These are materials that are often in direct competition of each other on the farm and a challenge to supply completely with smaller land holdings or available labor. A mulch for example, may be in direct competition with livestock fodder, thus making it a challenge to feed it out while still producing enough mulch. Using some of that same material to produce a compost or a fuel becomes even more challenging still.
