Bioreactors in tiled fields could themselves benefit from draining

Bioreactors are meant to filter nitrogen from tile water to help with runoff nutrient loads, but drying them out from time to time might increase their effectiveness

Bioreactors are meant to filter nitrogen from tile water and reduce extra nutrient running off int0 local rivers and lakes, but drying them out from time to time might increase their effectiveness.

Turning excess water into an asset with consolidation drainage

Farmers in the “prairie pothole” region are using its natural storage capacity to their advantage

After heavy rains flooded his yard, a Saskatchewan farmer turned to a consolidation drainage and irrigation project to better manage water on his land. Here’s how it works — and how the WSA and funding help make it happen.









tile for field drainage

Tile drainage can help manage nutrients as well as moisture

A South Dakota producer says improved draining not only increases plant health but also keeps nutrients on the field

The big benefit of tile drainage is preventing soil from becoming saturated, a major detriment to root development and crop yield, South Dakota farmer Brian Hefty says. “Plants will not grow into a water table.”


How plants conserve moisture in dry conditions

How plants conserve moisture in dry conditions

Plants do best when they have a little more moisture than they immediately require

In order to take in carbon dioxide to perform photosynthesis, a plant loses water vapour to the atmosphere as the stomata open. To counteract this, a steady supply of water is needed — hence what’s called the “transpiration paradox.”
