Drainage Design Parameters to Reduce Soil Compaction

Heavier, more efficient farm machinery is needed to produce cereals and grains for the growing population. The weight of this heavy machinery reduces the air space between soil particles causing soil compaction. This is particularly damaging on heavier soils that are intensively cultivated without rotations. Soil compaction impedes the flow of water through the soil profile, thus resulting in surface ponding of water in the field. Plants also cannot uptake water easily in compacted soils, thereby slowing their growth and development. Subsurface tile drains are linstalled below ground to facilitate the movement of water through the soil, therefore creating a healthier soil-root environment. We are partnering with the Land Improvement Contractors of Ontario (LICO) to study the relationship between soil compaction and drainage performance, and to determine the ideal drainage design by observing how far apart and how deep underground drains should be placed to prevent compaction. This project will benefit LICO because it will provide them with better information about drainage designs and installation, which could increase their pipe sales to farmers. This project will benefit Canada by improving agricultural productivity and food security while protecting our land.
