Tile drain observation -- installation to harvest
Spring to Fall 2021 by Ashley Adair, Purdue Extension Organic Agriculture Specialist
Pattern tile installation occurred on this field during winter 2020-21 with 50-foot lateral spans connected to main tile lines. The upper left quadrant was not tiled at this time, so it is possible to see tile installation recovery and observe differences in drained and undrained areas. The 80-acre field is located in northern Montgomery County and was planted to group 2.8 soybeans this year.
Discing and planting the field leveled out the ridges from tiling, but the ground was not completely settled even during harvest in November as indicated by combine tracks.
Notice in the late season images that many of the tiled areas of the field are showing less stress (greener in the RGB and NDRE plant health maps); however, the six weeks leading up to this point we only saw 2.5 in. of rain. The field is showing some drought stress and some struggles with water hemp.
