  For three weeks every month, Ray Archuleta captivates audiences with a few handfuls of soil. He begins with two clumps, dropping them into water. The soil from a farm where the soil isn’t tilled holds together, while the tilled soil immediately disperses, indicating poor soil structure. Next, volunteers from the audience — mostly farmers and ranchers — pour water over a soil that grew a variety of crops, and it runs right through. A sample of tilled soil that grew only corn is like a brick, and...

  Soil erosion is not unusual. In fact, it’s a pretty common occurrence around the world. When topsoil is disturbed, this layer of ground gets moved from here to there—fertile soil for farming can be lost, and wild lands can have a difficult time regenerating. Whereas soil erosion is typically thought of as a slow acting process, in reality, there is no real way of knowing just how slowly or quickly this problem can develop. For example, low rainfall may yield minor soil loss or simple ground disturbance,...
