And some farmers only grow these crops in a conventional monoculture no different than typical row crops or livestock systems. True, there is some efficiency gained in focusing on one crop system and designing all processes to take advantage of economy of scale. But as we are finally seeing, large-scale monocrops are subject to their own risks, not the least of which is the impact of commoditization and price volatility.
So large-scale row crops depend on large-scale farms for profitability, making diversification unfeasible. Similar mentality can be observed in the large monocropping of tree fruits. So designing a cropping system around scale to obtain efficiencies ultimately limits flexibility and ability to capitalize on any sort of market fluctuation. Basically, the more of a single crop a farmer plants, the more of that same crop must be planted to stay profitable. Expand or die, as they say...
Okay, so large monocrop farms cannot afford to diversity for fear of falling behind. Small scale farms must diversify to make the best use of limited resources but generally cannot support the larger investment up front and longer payback for a more valuable crop...
What would happen if a moderate farm could support several high value crops on small scales? I'd love to see it...
