This is something I hadn\’t realised (shows how much of a city boy I really am):
Under my crop rotation, I grow wheat five times in a decade, and produce nearly four tons an acre. My organic counterpart will grow wheat only three times, yielding around two tons per acre. In the time I have produced 20 tons, he will be lucky to get six. And in the intervening years I can grow sugar beet, peas, beans or oilseed rape, whereas he needs to rest his soil with clover and grass.
Whenever we see comparisons of the yields between organic and conventional farming we see them presented as one year yields. Or at least, that\’s the impression I have.
But the need for the organic farmer to leave land fallow obviously flatters such comparisons if we try to measure what we really want to know, which is production over time.
Yields from organic are thus even worse than I had thought, no?
