Former pesticide factory goes under the dome

An inflatable cover the size of three football fields 
is designed to keep odour under wraps

A Chinese company in the eastern city of Hangzhou, China has constructed a massive inflatable dome over the site of a closed-down pesticide factory, state media reported May 14. While it covers an area the size of roughly three football fields, the 20,000-square-metre polyester dome still covers less than half the contaminated zone, according to

Reading soil tests key for proper nutrient use

The devil is in the details when it comes to nutrient application, 
meaning there is no silver bullet, just lots of hard work

If you’re planning on going somewhere, it’s best to know where you are starting from before you head out. The same can be said of soil fertility. According to Brian Hefty of Ag PhD, too many producers make assumptions about soil health and nutrients when deciding what inputs to use on their field crops. “Soil

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

Is the freeze-thaw effect a myth?

What if the notion that the freeze-thaw action of icy winter weather gives Prairie farmers a free pass on soil compaction problems turns out to be wishful thinking? If so, the implications should be enough to send a chill down a big-iron-loving farmer’s spine. “We often say that we don’t have to worry about soil

Soil scientist Jon Stika demonstrates the erosion-resistant qualities of a “living” soil aggregate (r) compared to an ordinary clump of “dead” dirt.

Healthy soil the key to healthy profits

Look beyond ‘bench-top chemistry’ in evaluating soil health, urges soil microbiologist

Jon Stika says farmers always give the same answers when asked what they want from their soil. “They want it to grow crops, infiltrate water and supply nutrients,” the USDA soil scientist told last week’s annual workshop of the Manitoba-North Dakota Zero Tillage Farmers Association. “But what if we managed it to its fullest potential,


Dry soil a concern for some on the Prairies

Dry soil conditions heading into winter could cause problems next spring. “There are some concerns with pasture recovery and just starting up the season next year,” said Trevor Hadwen, agro-climate specialist with Agriculture and Agri-Food Canada. “In terms of native pasture, the dry fall doesn’t allow the recharge of the soil moisture, which doesn’t allow

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


Manitobans helping North Korean farmers

Manitobans with expertise in zero till and soil health are helping farmers increase productivity in the isolated nation

When it comes to North Korea, agriculture may not be the first thing that pops into people’s minds. But for the Mennonite Central Committee (MCC) it’s been front and centre for the last five years. The Winnipeg-based organization has been providing farmers in the Democratic People’s Republic of Korea with assistance with soil conservation and

White spots speak volumes about alfalfa’s needs

Alfalfa can pull down its own nitrogen from the atmosphere, but can’t conjure up 
phosphorus, potassium, sulphur, and boron out of thin air

Alfalfa isn’t a plant that complains a lot, but white spots on its leaves are a clear plea for more potash. After poking around in the field surrounded by whispering poplars at the recent Hay Day tour near Neepawa, provincial soil fertility specialist John Heard pointed out a shining example of “full-blown potassium deficiency.” Farmers
