Fluorescence Reveals the Incredible Productivity of America's Corn Belt

During photosynthesis, the chlorophyll in healthy plants absorbs light to be converted into energy, but it also emits a little bit of light that’s not visible to the human eye. Scientists have now figured out how to use that fluorescent glow to measure the productivity of plants in a given region.

Using existing data from satellites designed for entirely different purposes, such as ozone monitoring, NASA scientists were able to show that during the Northern Hemisphere’s growing season, the midwestern U.S. has more photosynthetic activity than anywhere else on the planet, including the Amazon (the tropics are more productive on a yearly basis, however). Nearly all of this can be attributed to agriculture in what is sometimes called America’s Corn Belt — where, unlike the rainforest, crops are bred, engineered, and managed to be as productive as possible.

The image above is a compilation of data collected each early July from 2007 to 2011. The scientists think that fluorescence is a better measure of agricultural activity than anything currently used. And when they compared their results against ground measurements of carbon flux and yield statistics, they checked out.

‘It’s another blow’: Farmers deal with surging fertilizer prices ahead of seeding

Fertilizer is an essential part of Kevin Peters’ farm in southwestern Manitoba. But since Israel and the U.S. attacked Iran, the average price of urea fertilizer, which is widely used around the world, has skyrocketed, surging around 30 per cent over the last week. Peters says the interruption in supply didn’t come as a huge surprise to him. “We deal with geopolitical issues all the time with markets, be it pork, be it grain, and now fertilizer,” he said. “There’s always some disruption seeming to happen somewhere in the world that is changing our daily prices.” Peters says he pre-purchased his fertilizer for this farming season back in the fall but is concerned about prices later this year when he has to buy fertilizer again. “We’ll see what the market looks like in eight months,” he said. Like Peters, Andrew James also pre-bought his fertilizer in the fall for his farm in Anola, Man., and he says he is happy he did. “My fertilizer bill for that (at the time) was around $350,00

From a Piece of Wire to Contaminated Feed: Preventing Foreign Material Hazards in Beef Cattle Operations

Foreign material and toxin consumption by beef cattle can lead to significant health problems, reduced performance and economic losses. Canadian cattle producers take great pride and care in how they manage their farms and ranches, from providing proper nutrition to stewarding their land and ensuring excellent animal care. Yet even with the best intentions, foreign materials and toxins can quietly find their way into feed, water or pastures. Understanding where they come from and how to prevent exposure is a key part of protecting your herd. Foreign materials and toxins often slip in through everyday farm activities such as repairing fences, running equipment, feeding hay or dealing with weather-stressed crops. A small piece of wire, leftover net wrap or contaminated feed source might not seem like much, but if consumed by cattle, it can trigger health issues, lost performance or even death. Understanding Hardware Disease When cattle consume sharp metal objects like nails or pieces

Farmers Balance Costs and Technology Investments - Tractor Sales Down

Tractor sales fell across most categories in February, but strong combine demand highlights farmers’ continued investment in productivity boosting technology.

Principal field crop areas, 2026

Canadian farmers expect to plant more canola, barley, soybeans and corn for grain in 2026, while they anticipate area seeded to wheat, oats, lentils and dry peas to decrease compared with the previous year. Wheat At the national level, farmers anticipate planting 26.7 million acres of wheat in 2026, down 1.1% from the previous year. If this anticipation is realized, national wheat area would remain well above the five-year average, despite a decrease from 2025, which would likely be attributable to continued strong global demand. Producers expect spring wheat area to edge down 0.1% to 18.8 million acres in 2026. They anticipate durum wheat area to decrease 2.4% to 6.4 million acres, while they expect winter wheat area to fall 6.7% to 1.6 million acres. Farmers in Saskatchewan anticipate planting 13.9 million acres of wheat in 2026, down 1.0% from the previous year. Producers expect spring wheat area to fall 0.6% to 8.7 million acres, while they anticipate durum wheat area to remain
