Introducing PLATO, the Phosphorus Loss Assessment Tool for Ontario

Jul 02, 2020

Keeping soil covered and minimizing erosion is a key principle of soil health. Maximizing the efficiency of crop nutrient uptake and minimizing losses are the foundation of 4R Nutrient Stewardship. When combined, these principles form the basis of a new online tool from OMAFRA called PLATO (Phosphorus Loss Assessment Tool for Ontario).

PLATO is a calculator that you can use to estimate the risk of phosphorus loss on your farm. It’s part of the newly re-vamped AgriSuite and uses your specific soil, crop and nutrient application information to provide a risk rating and options to improve your score.

Whether you’re considering a new way to apply fertilizer or manure, or you’d just like to know how you compare to your neighbours, PLATO provides answers.

How does it work?

You provide your county and geotownship, along with your soil series, soil texture and a soil test phosphorus value. Next, you select a crop type, tile drainage system and spacing details, and an estimate of erosion. Erosion can be calculated quickly by providing a maximum slope and basic tillage information or estimated more accurately by using the new Water Erosion Potential Map in AgMaps.

Video: What Does 20 MILLION Hogs a Year Look Like?

?? The Multi-Plant System Processing 20 Million Hogs Annually in the Midwest JBS USA operates multiple large-scale pork processing facilities across the Midwest, including major plants in Iowa, Minnesota, and Indiana. Combined, these facilities have the capacity to process approximately 20 million hogs annually.

Each plant operates high-speed automated slaughter systems capable of processing up to 20,000 head per day, followed by fabrication lines that break carcasses into primals, sub-primals, and case-ready retail products.

Hog procurement is coordinated through electronic marketing platforms that connect regional contract finishing operations and independent producers to plant demand schedules. This digital procurement system allows for steady supply flow and scheduling efficiency across multiple facilities.

Processing plants incorporate comprehensive food safety systems, including pathogen intervention technologies, rapid chilling processes, and integrated cold-chain management. USDA inspection is embedded throughout the harvest and fabrication stages to ensure regulatory compliance and product integrity. Finished pork products — from bulk primals to retail-ready packaged cuts — are distributed through coordinated logistics networks serving domestic and export markets.
