Adapting as You Go: Grazing Decisions at Palmer Ranch

Palmer Ranch | Regenerative Alberta Living Lab

Palmer Ranch sits in the southwest corner of Alberta's Foothills region. Julia Palmer and Uriel Delgado Montano run about 450 mother cows on the home place, with another 500-cow herd near Lancer, Saskatchewan. The operation has been in the Palmer family since Julia's grandfather Morris purchased it in 1968.

Managing in a drying climate, on land with a complicated history, has meant staying responsive rather than following any single playbook. The clearest way to see how that plays out is to follow one field.

A field that gave out

Field 32 is 330 acres on the north end of the ranch. Julia remembers it as a kid: grasshoppers and dirt, almost nothing growing.

When BSE hit in the early 2000s, herd values dropped overnight and inputs stopped. No fertilizing, no reseeding, no tilling. Field 32 was cut for hay year after year and grazed for regrowth in the fall, with little coming back the other way.

“We took everything, and we didn't put anything back,” Julia says. “We kind of started going, ooh, we've got a problem, because our yields were really low - like, we were getting half-ton yields for hay.”

It was bad management, she says plainly, compounded by not addressing the underlying issues. The question that followed was simple: what would it take to start putting something back?

Rethinking the hay loop

One of the bigger changes came from reconsidering something that had felt non-negotiable: making hay. Cutting, baling, storing, and hauling hay back out to the same fields every winter is a full loop of cost and labour, and it was carrying fertility off the land season after season.

So they stopped. “We don't make any of our own hay anymore,” Julia says. Instead they bring hay in and bale graze it on the land, budgeting around five pounds per animal per day of purchased supplemental feed while cattle graze stockpiled forage through winter. Rather than hauling nutrients away, winter feeding now lays them down on the ground where they're needed. It also simplified the operation: what had been five or six separate herd groups is now two, optimized around forage use.

Learning to move on Field 32

The other half of the shift was grazing, and Field 32 is where they worked it out. Last August, conditions were dry and the grass had lost palatability. A group of 380 bred replacement heifers needed to be gaining, but weren't eating well enough on what was available.

Uriel used Google Maps to divide the field into strips, then into smaller paddocks. They started moving the heifers once a day. Performance wasn't where they wanted it. Twice a day, still not quite right. Three times. Then four.

“The performance kept up, and they utilized the grass like amazing,” Julia says. “And they get so quiet.”

The heifers averaged 1.8 pounds of gain per day through a dry summer, with strong conception rates. It wasn't a plan they'd made in May. It was a response to what the season was telling them, and it showed what frequent moves could do for both the animals and the even use of the field.

Field 32 today

What started as a dry-summer experiment is now how Field 32 is managed. The field that once grew grasshoppers and dirt is rotationally grazed, with cattle moved up to four times a day so grazing and nutrients are distributed evenly across it rather than concentrated in a few spots. Hay is brought in and bale grazed there, putting organic matter and nutrients back onto the same ground that was mined for years.

It is the same field, managed on opposite principles. Where the old approach took everything and returned nothing, the new one is built around keeping fertility on the land and spreading it where it does the most good.

Why it matters, and what the Living Lab is tracking

Grazing decisions like these sit at the centre of a long-standing debate in rangeland management. Take half, leave half has been a widely used guideline, with higher utilization common in tame pastures, while other approaches push toward far more frequent moves and higher stock density. What the research has struggled to resolve is whether the label on a system, rotational, adaptive, continuous, actually predicts outcomes. In practice what matters is what happens on the ground: how long animals are in a paddock, how often they move, and how long the land gets to recover.

In a drying climate, the stakes are rising. Soil organic matter and water holding capacity are closely linked, so land with more biological activity holds more moisture and buffers better against dry years. That is the real reason to care how a field like 32 is grazed and fed.

Julia was part of the group of producers who helped define the Regenerative Alberta Living Lab's research questions at the outset, in part because the existing research wasn't capturing what producers actually needed to know. The Living Lab is now tracking grazing decisions across a spectrum of approaches, from take-half-leave-half to much higher utilization, using a custom grazing app and three rounds of soil sampling, to connect what producers do on the ground to changes in soil carbon, soil health, and resilience.

You can see it in the soil

It is already starting to show. On Palmer Ranch's soil carbon maps, the areas where they bale graze stand out as distinct patterns: the spots where winter feeding has been putting nutrients back are the spots where carbon is building. The field that was the problem is becoming the proof.

“Science knows how to document knowledge,” Julia says. “We never kept records, we didn't do that. And so now, may we create the data set that allows for the innovators, 20, 30 years from now, to be innovative.”

The next post looks closer at those carbon maps, including what happened when a field the Palmers once managed was later tilled, and where the bale grazing signal still showed up.
