Long-time farmer Gene Logsdon has been thinking about manure a lot. In fact, he says it is our most misunderstood natural resource.
Longson wants us to go back to the days of grazing animals and letting them fertilize the land for more crops, because, he argues, it’s the pitchfork-wielding farmer that takes animal waste and turns it into the food that sustains us.
Finding ways to turn all our waste into fertilizer is crucial to our survival, says Logsdon, and he sees a future when companies might actually pick up refuse from homes and sell it to farmers.
We are revisiting our conversation with Logsdon about his book “Holy Sh**,” and our follow-up with Cornell professor of soil chemistry Murray McBride, who reminded us that especially when it comes to human waste, there are still some serious hurdles to be overcome, because human waste can retain medicines, and even radioactivity from medical treatment.
