Another reason to love @BigPictureAg: Great guest post on drought from p.o.v. of parched Iowa farm. Excerpt:
With the corn crop currently denting, and thus “fixed” (more rain would not now improve yields), all attention turned to soybeans. Beans have a resilient character to them, with the capacity to shed blossoms until growing conditions “are right.” Having lost much of the corn crop, our neighbors are busy reassuring each other that “the bean crop is made in August”—but only if rains arrive. Unfortunately, there is little moisture predicted in the medium-term forecasts.
Worst hit of all have been the livestock producers. Pastures are toast, and watering holes and rivers are drying up…. THE REST
PNAS paper linking climate-driven crop failures to Mexico-US migration rate created buzz, now challenged in same journal.
