According to Dr. David Montgomery, author and professor at the University of Washington who spoke to farmers during the 22nd Annual No-Till on the Plains Winter Conference, our soils around the world have been severely degraded due to conventional agricultural practices. In a recent interview with Radio Oklahoma Ag Network Associate Farm Director Carson Horn, Montgomery says soil degradation has taken on two forms in modern times.
“One, is the erosion and loss of soil itself, like what happened in the Dust Bowl for example,” Montgomery explained. “But also, in terms of degraded soil organic matter – the carbon that’s in the soil. You can think of it as food for the microbes that actually help build soil fertility.”
Listen to Dr. David Montgomery and Carson Horn speak about how regenerative agriculture can reverse the effects of soil degradation here.
Montgomery says in North America, about half of our soil organic matter has been degraded, averaged across the United States. Globally, he says, it is about the same. Not only is that a devastating amount to have lost, it is also continuing to be lost at an alarming rate.
“The pace of global soil degradation at present, shows we’re losing 0.3 percent of our agricultural land capacity globally each year,” he said. “That sounds like a small number, but you play that out over the next 100 years and we’d be on track to lose a third of our agricultural productive capacity while we’re on track to raise our population by 50 percent. Those numbers are working against each other.”
