Visited the plot on Wednesday (5/14). The sub-drainage appears to have been very effective in removing the the water and allowing the roots to develop as you can see the difference between the two corn plants in the picture. You will notice the non -drained plant is shorter and the roots are also much shorter than the plant on the tiled ground. The water control structure’s have been closed to conserve moisture as the John Deere Field Connect moisture monitoring probe is indicating that the watertable has been sufficiently lowered to promote proper root development.
