A New Way to Predict Grazing Cattle Weight Gain on Rangelands From Satellite Imagery

By Maribel Alonso

USDA’s Agricultural Research Service (ARS) developed a unique approach to using satellite imagery to predict cattle weight gain on rangelands. By fusing multiple images over a period of time, scientists were able to monitor how forage quality changes over space and time in rangelands within the shortgrass steppe, and how this relates to the weight gain of free-ranging cattle throughout the summer grazing season.

Managing the grazing season in rangelands can be challenging due to high variability in temperature and rainfall over time. From a manager’s perspective, it is essential to know when and where forage production and quality are changing to optimize free-range livestock weight gain and meet other environmental objectives. This is not just about chasing forage quantity (total amount of vegetation biomass); it is also about looking for the highest-quality forage throughout the season.

Why Port Infrastructure is Key to Growing Canada's Farms and Economy

Video: Why Port Infrastructure is Key to Growing Canada's Farms and Economy

Grain Farmers of Ontario (GFO) knows that strong, modern port infrastructure is vital to the success of Canada’s agriculture. When our ports grow, Ontario grain farmers and Canadian farms grow too—and when we grow, Canada grows.

In this video, we highlight the importance of investing in port infrastructure and how these investments are key to growing Ontario agriculture and supporting global trade. The footage showcases the strength of both Ontario’s farming landscapes and vital port operations, including some key visuals from HOPA Ports, which we are grateful to use in this project.

Ontario’s grain farmers rely on efficient, sustainable ports and seaway systems to move grain to markets around the world. Port investments are crucial to increasing market access, driving economic growth, and ensuring food security for all Canadians.

Why Port Infrastructure Matters:

Investing in Ports = Investing in Farms: Modernized ports support the export of Canadian grain, driving growth in agriculture.

Sustainable Growth: Learn how stronger ports reduce environmental impact while boosting economic stability.

Global Trade Opportunities: Improved port and seaway systems help farmers access new global markets for their grain.

Stronger Communities: Investment in ports means more stable jobs and economic growth for rural communities across Ontario and Canada.

We are proud to support the ongoing investment in port infrastructure and to shine a light on its vital role in feeding the world and securing a prosperous future for Canadian agriculture.

Special thanks to HOPA Ports for providing some of the stunning port footage featured in this video.
