Too early to alter nitrogen guidelines

Solid manure applications may actually release more nitrogen over time, not less

The questions, how much nitrogen was applied and how much is available don’t have the same answer. Seven crops into a long-term study on nutrient management at the National Centre for Livestock and the Environment, researchers have found that current provincial guidelines for estimating nitrogen availability may not reflect reality when it comes using solid

Manure improves organic forage-grain crop production

‘Experimental lakes of agriculture’ find organic crops can produce on par with conventional crops

Organic crop producers can match the productivity of their conventional farming neighbours with a little help from some four-legged friends. Composted beef and dairy manure restores important nutrients that can be mined from the soil under organic management systems, Martin Entz, an agronomy professor with the University of Manitoba’s Glenlea research station told participants in

Conservation and livestock can be a good mix

While intensive livestock production can cause waste and nutrients to pile up, 
mixed farms are better able to recycle nutrients

When Ian Grossart harvests alfalfa on his farm in southwestern Manitoba, he knows where most of the nutrients he’s just removed are going to end up — back on his land. “With the cattle we compost all of our own manure, so that becomes a big part of our fertility program,” he said. “And because

New research says standard formulas overstate 
the amount of nitrogen released

Standard calculation formulas overestimate the amount of nitrogen that is available to crops the year after solid manure is applied to the field, researchers with the National Centre for Livestock and the Environment (NCLE) say. Don Flaten and Wole Akinremi say the formula that is used in Manitoba is based on the assumption that 25

Struvite from manure safer in canola seed row

Manitoba Soil Science Society serves up a heaping helping of new research

There’s a whole lot of stinky goodness in hog manure, and researchers at the University of Manitoba have been working hard to make it more convenient for grain farmers to use. Experimental extraction of struvite, or magnesium ammonium phosphate — the same greyish-white crystallized minerals that kidney stones are made of — has shown promise as

Four Rs keep the regulators at bay, MSSS hears

Right source, rate, time and place are the best guides for staying on the straight and narrow

Widespread adoption of voluntary protocols for balancing soil fertility requirements with the need to protect surface water quality will be far more effective than legislation, the director of the International Plant Nutrition Institute says. Tom Jensen told the recent Manitoba Soil Science Society’s annual conference farmers can maintain crop yields and minimize adverse environmental effects


KAP president angry over fall fertilizer ban

Doug Chorney, the normally calm, cool and collected president of the Keystone Agricultural Producers (KAP), is steaming mad at the Manitoba government for failing to accommodate farmers wanting to apply fertilizer and manure to their fields last week. “I’m really upset because we were misled and I think it was deliberate,” he said in an

National soil science meeting meets Manitoba mud

A look back in time on Manitoba's escarpment — and a vision of what the future could be

Dale and Caroline Steppler’s farm on the Manitoba Escarpment was shaped by glaciers, 
but today the challenge is keeping nutrients from running down to Lake Winnipeg

In an abandoned shale pit a busload of muddied-shoed soil scientists from across Canada and beyond peer back millions of years into the geological history of this part of the Manitoba Escarpment west of Miami. Marine dinosaur fossils are routinely discovered nearby in the bentonite clay formed from prehistoric volcanic ash. They once swam in


Cows and crops: A perfect combination, experts say

Fifteen years ago, Marc Boulanger and his family took a closer look at what was happening on their operation near Grande Clairière, Man. — and didn’t like what they saw. “In the late 1980s, when grasshoppers were a major problem, we’d spray — then we were watching how the grasshoppers died, then the birds were
