Farmers will follow harvest recommendations
“How can you ensure farmers are harvesting a responsible amount of biomass?”
That question has popped up a couple times when discussing our soil data showing that POET’s removal rates (about 1 ton/acre) are consistent with good farm management. Some people are concerned that farmers won’t leave enough biomass on the ground when they know they could get paid for it.
We’re confident that won’t happen. Fields around Emmetsburg will maintain appropriate cover after the biomass harvest, as illustrated in the photo above.
First, the POET people in Emmetsburg know these farmers and work with them. If a farmer has 1,000 acres, he or she won’t have a contract that calls for 3,000 tons of biomass. The contract reflects a responsible amount of corn cobs, leaves, husks, and some stalk, and it leaves room to account for unforeseen problems with yield or available acres.
Second, POET Biomass team members in Emmetsburg drive the country roads and visit participating farmers to check out how things are going. This fall, they helped fine tune harvest operations to clear up some early misunderstandings. Check out a summary of their work in this presentation.
Third, stover is not the primary cash crop for these farmers, and they won’t jeopardize soil health for extra bales. The farmers have been cautious moving forward with biomass harvesting for the same reasons POET has been cautious: This won’t work if it’s not done sustainably.
We commissioned Iowa State and USDA to gather soil data because the farmers need that information. We’re not forcing it on them; they’ve asked for it.
