Description
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.
Objective(s)
- Determine optimal parameters for designing underground irrigation systems
- Evaluate the behavior of water table levels and determine key control parameters for maintaining an ideal moisture level in the sphagnum mat
- Develop a basic moisture balance strategy to allow automation of the irrigation system
From 2013 to 2017
