CTA announces Volume-Related Composite Price Indices for Crop Year 2024-2025 for CN and CPKC

GATINEAU, QC,  - The Canadian Transportation Agency (CTA) has announced its determination of the Volume-Related Composite Price Index (VRCPI) for the Canadian National Railway Company (CN) at 1.9281 and the Canadian Pacific Kansas City (CPKC) at  1.8760 for the 2024–2025 crop year beginning August 1st. This is an increase in the VRCPI over the last crop year of 5.39% for CN and 6.49% for CPKC.

The determination of the VRCPIs is based on detailed submissions from CN and CPKC on their historical price information for railway inputs involving labour, fuel, material, and other capital items as well as forecasted future changes in these railway price components.

These indices will be used in determining CN's and CPKC's Maximum Revenue Entitlement for the movement of western grain in the 2024–2025 crop year. The Maximum Revenue Entitlement limits the overall revenue earned by CN and CPKC for shipping regulated grain.

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

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.
