Long distance transport of both inputs and outputs of farms raises
questions of energy extravagance and food security, and therefore
ultimately questions of sustainability. 400 acre dairy farmers around
here don't even find it economical to recycle organic matter to their
outlying fields! Isn't that a problem of scale? But I see no problem of
sustainability with two farms collaborating on organic matter recycling
as long as transport costs are reasonable. In traditional societies there
are plenty of examples of grazers wintering their animals on the lands of
tillers, trading manure for animal products, for example.
