On a recent rainy day, farmer Allen Druffel stands outside a silo shuffling his feet in the gravel. This co-op bin is where he stores his dried garbanzo beans in the tiny town of Colton, Wash. The place should be busy; trucks should be loading and hauling this year's crop to markets and international ports. But midafternoon, there's just the rain. Since farmers like Druffel brought in this year's crops, hardly any garbanzos — or chickpeas — have moved."Thirty to 40 percent of our total revenue is in the bin," Druffel says. "And we're not sure what we want to do with it."And it's bad times for lentils and peas, too. In the agriculture industry, these are all called pulse crops. The largest importers of U.S. pulse crops have slapped tariffs on them, and they've been sitting in silos ever since.
