4R strategy plays a key role in reducing phosphorous runoff
Three short huts with solar panels on them sprout in Bob McIntosh’s wheat field near St. Marys, Ontario.
Inside the huts are monitoring equipment that goes right to the tiles that systemically move water from his farm. His farm is one of six across Ontario with the monitoring equipment that allows University of Waterloo researchers to study how water, and especially the phosphorus in it, flows off of farms.
“We’re trying to capture the natural variability in the Ontario landscape,” says Dr. Janina Plach, who is doing post-doctoral research at the University of Waterloo.
