A couple quotes from the article:

"It’s probably only a matter of time before Cargill, Archer Daniels Midland and others come up with similar incentives. I certainly would prefer to see the market, rather than government regulations, drive the use of cover crops."

• Incentives from buyers/processors often evaporate or reflect the minimum $ amount necessary to create an outcome.
• Sustainability in the eyes of many (buyers/processors/consumers) is at times green washing and a component of marketing rather than true support of the concept. 

"It’s a delicate balancing act between environmental responsibility and economic success, but more and more farmers are discovering the value cover crops offer, both in the Mid-Atlantic region and around the world."

• Steve brings this back to reality with this statement. The reality is that the benefits farmers are seeing is what is driving the increased implementation on more acres.
