Glacier FarmMedia – They’ve been dubbed “crazy strips,” but there’s a method to Mike Groot’s patchwork of perennial pasture stands within a larger plot trial.
The Ontario farmer is a participant in a project being conducted under the Living Labs initiative, a federal program that tests innovative practices and technologies on farms.
Groot is hoping the soil quality data it gathers will eventually show that including pasture in a cash crop rotation isn’t crazy at all.

He has an ally in Christine O’Reilly, a forage and pasture specialist with Ontario’s ag ministry who was among presenters at a recent event at the Groot family’s Wholesome Pastures farm.

“Usually, if we’ve got something in rotation with corn, beans and wheat, it’s alfalfa,” O’Reilly said of the dominant southwestern Ontario farm landscape. She noted the term “ley” — with a dictionary definition of “arable land used temporarily for hay or grazing” — was commonly used in the past in North America and has never lost favour in Europe. That’s because fertility and yields on the cropland have typically been high after a time in pasture.
After signing on to be part of Living Labs in 2020, Groot planned to include a year of grazed annual cover crops as part of his test plot rotation. But he decided it would be too challenging to consistently get the cover crop established after wheat, graze it in fall and then terminate it for another crop in the spring.
Instead, he established a series of three-year stands of rotationally grazed perennial pasture species within a much wider plot including corn, soybeans and wheat. In all, it includes two dozen 80-foot plots of approximately one acre each, an approach dubbed “crazy strips” by fellow Living Labs participant Woody Van Arkel.
“I know some of those annual crops have big biomass too, but I think having those long-term perennials building root masses is even better,” Groot said of his decision to alter the approach.

On his farm, researchers are studying the use of rising plate meters to develop an approach to measuring pasture yield and also analyzing soil microbes under various treatments within the plot.
It’s nothing new for the Groots to be part of innovative farm practices. The family direct-markets beef, lamb, chicken, duck, eggs and honey in their raw form and through value-added products like soaps, lotions and leather. Sixty-inch corn rows have served as free-range chicken habitat.
For the Living Labs research, no manure from the barn will be spread on the strips. There are enough other fields on the 160-acre home farm plus some surrounding properties that need fertility.
As well, a control strip will not be grazed, allowing for analysis of microbial activity as a result of both ley and livestock being present as opposed to simply including ley in the rotation.
A group of 10 heifers are being rotationally grazed through the pasture strips. Fencing added to the labour of setting up the trials, but electric fence had already been installed around the perimeter of the home farm as well as 25 acres on a neighbouring farm.
Citing climate action-themed funding opportunities that cover up to 60 per cent of costs, Groot is hoping to fence another 80 acres this year.
