Food Security with The Corn & Wheat Belt looks Dismal
I have Been tracking farm reports about fuel prices, droughts, fertilizer shortages,Dust bowls and now No topsoil. This is could be a serious threat to national security soon if we lose our bread basket here in The USA. This is not a drill!
Scientists and farmers know that agricultural soil erosion has been a problem for decades, but quantifying soil loss from a hundred years of farming and across multiple states has proven difficult. Now a 2021 study led by geomorphologist Evan Thaler and published in Proceedings of the National Academy of Sciences attempts to answer the elusive question of how much topsoil has been eroded in the Corn Belt, which stretches roughly from Ohio to Nebraska and produces 75 percent of the nation’s corn. The study estimated that about 35 percent of the region has lost its topsoil completely, leaving carbon-poor lower soil layers to do the work of supporting crops. Having thick, healthy topsoil means plants can grow faster and healthier, increasing crop yields and keeping the field’s ecosystem running smoothly.
