摘要

Soil residue made the difference for Ryan Speer during the long, parched summer of 2011. Lack of rainfall in south-central Kansas teamed up with 52 days of 100° F or higher readings to devastate crops nearby. But he got a first-hand look at how protecting the soil can pay dividends. "We were able to keep the soil surface cool so the soil's biological life could remain active and create organic matter, helping make these soils to be more productive even in the middle of a terrible drought," he says."The residue on the soil surface is what allows that to happen." After 100 years of tillage on soils in his area, Speer says the level of organic matter has been dropping, in some cases falling to 1.5% or less. "The soil has been degraded, and my hope isto slowly build it back up into a more sustainable state," he says.
