It has been shown that maintaining the water table close to the soil surface helps sphagnum moss grow and reduces CO2 emissions from sphagnum farms. The objective of this project was to develop effective techniques for controlling water table levels in sphagnum moss basins. Underground irrigation systems were installed at a number of experimental sites. The effectiveness of the systems was evaluated by monitoring water levels at different locations in the sphagnum basins.

Canola and wheat (wheat-corn-canola rotation) were planted in 2016 and 2017, respectively, on 12 experimental plots with tillage practices on the main plots (minimum tillage and chisel plow) and fertilization methods (mineral fertilizers, 25 m3/ha of pig manure and 50 m3/ha of pig manure) in the subplots.
The project evaluated and compared the effectiveness of two types of subsoil plows (mounted on a bulldozer or a tractor) operated parallel and perpendicular to the tile drains to improve soil drainage conditions and productivity compared to control plots.

This project looks to develop decision-support tools informed by observations of “bellwether” plots and use these tools to disseminate relevant information to irrigators.
