If you farm in the Delta, then you probably are farming in Sharkey Soil. Often referred to as Gumbo, the heavy clay soil is poor draining and slow to permeate, and usually prevents farmers like Matt Miles from working their fields until late spring at earliest. This year, Matt Miles took the very unusual step of installing drain tile in one of his fields.  He explains the decision, expected ROI and results he is already seeing in his first spring with his new tile system from Advanced Drainage Systems.
