See what we do in the Biogeochemistry Lab! youtube.com/watch?v=9Z5_QGxv… (Thank you @JaninaH2O for putting this amazing video together!)
H! The UTRCA is also working with controlled drainage, as is ABCA. We also have some results! DM me and we can connect!
Shawn, I just read your post asking for controlled drainage and sub-irrigation data. Dr. Merrin Macrae @merrinm was involved in a collaboration in ON and QC about a decade ago. Here's a report, although Merrin will likely have others to share: ouranos.ca/en/projects-publi…

#CatchmentHydrology
A poem
From @MelLuymes 😂
Beneath the earth, it stands so still,
Measuring the water's will.
A quiet gauge, a subtle eye,
Tracking the levels, low or high.
In wells it peers, in soil it sees,
The hidden flow, the groundwater's keys.
A piezometer whispers truths with ease.

Managing #phosphorus in agricultural fields is important for maintaining #WaterQuality Here are some ways that Dr. Merrin Macrae suggests ensuring phos stays in the soil, where it’s needed:
🌾Apply Phos at the right rate & draw down soil levels of phos in areas where they are noted to be elevated
🌾Apply fertilizers containing phos using subsurface application methods & gently incorporate manures instead of broadcasting
🌾It’s best to apply phos at the time of seeding & never on frozen ground
To learn more about targeting #BestManagementPractices that will have the greatest impact on water quality, check out this webinar from Dr. Merrin Macrae and Dr. Catherine Febria. youtube.com/watch?v=mCFp93fS… – at Strathroy-Caradoc, Ontario

Wayne Rouse was a driving force on my committee during my MSc and PhD. He cared deeply about Canada’s north, climate change, and everyone he met. Much of his work was ‘pre internet’ and now overlooked. Looking back, Wayne was far ahead of the curve in every way. Remember him.
