Implementation of the "4R Nutrient Stewardship Program" remains a priority

Oct 14, 2022

The Manitoba government, Keystone Agricultural Producers (KAP), and Fertilizer Canada have officially signed a new memorandum of understanding (MOU) focusing on 4R Nutrient Stewardship

The 4R Nutrient Stewardship was developed by Fertilizer Canada and focuses on applying the "Right Source at the Right Rate, at the Right Time, and in the Right Place.

Agriculture Minister Derek Johnson says initiatives that balance crop production with environmental protection measures are critical to ensuring Manitoba’s agricultural sector is well-equipped to meet the needs of future generations.

"This MOU supports and strengthens our government’s objectives in food security and affordability, in addition to environmental performance, with the nutrient stewardship programming developed by Canada’s fertilizer industry."

Video: Seeing the Whole Season: How Continuous Crop Modeling Is Changing Breeding

Plant breeding has long been shaped by snapshots. A walk through a plot. A single set of notes. A yield check at the end of the season. But crops do not grow in moments. They change every day.

In this conversation, Gary Nijak of AerialPLOT explains how continuous crop modeling is changing the way breeders see, measure, and select plants by capturing growth, stress, and recovery across the entire season, not just at isolated points in time.

Nijak breaks down why point-in-time observations can miss critical performance signals, how repeated, season-long data collection removes the human bottleneck in breeding, and what becomes possible when every plot is treated as a living data set. He also explores how continuous modeling allows breeding programs to move beyond vague descriptors and toward measurable, repeatable insights that connect directly to on-farm outcomes.

This conversation explores:

• What continuous crop modeling is and how it works

• Why traditional field observations fall short over a full growing season

• How scale and repeated measurement change breeding decisions

• What “digital twins” of plots mean for selection and performance

• Why data, not hardware, is driving the next shift in breeding innovation As data-driven breeding moves from research into real-world programs, this discussion offers a clear look at how seeing the whole season is reshaping value for breeders, seed companies, and farmers, and why this may be only the beginning.
