Tiling Poorly-Drained Soils Can Boost Yields & Gross Revenue

Purdue study shows economic, soil health & conservation improvements through tiling naturally-occurring wet soils, along with timely early-season planting
More than 35 years of research shows growers with “high water-table” soils can reap corn yield benefits from subsurface tiling and, at the same time, improve the effectiveness of their conservation practices.

Enabling No-Till Yields to Increase with Drainage, Earthworms - Doral Kemper - NNTC 2016 Presentation - MP3 Download

$19.95

In no-till systems, earthworms enjoy a synergistic relationship with corn roots. The earthworms subsist on decaying residue of the roots and the roots extend further when they can find earthworm burrows to go through. In this presentation, Doral Kemper discusses how this relationship is enhanced when tile drainage prevents the water table from rising and eliminating aerated portions of the soil the worms need to survive and grow. The retired soil researcher from USDA-ARS shares how drainage and earthworms aid in the extension of roots, which enables crops to access more water in the late — and often dry — portions of the growing season when they hit the critical grain-filling stage. Kemper also explains how soil drainage to extend earthworm and root activity makes it one of the farmer’s best investments.
