Weeds helped save his farm

Weeds aren’t always a farmer’s enemy. Sometimes they’re an ally. Grant Rigby says weeds helped him tackle soil salinity on his farm near Killarney and led him into organic agriculture. “The fundamental reason I dropped herbicide spraying was to allow plants to live on those areas of the farm where the crops I planted were

Science behind organic systems gains ground

Organic agriculture’s critics routinely claim the practice is more philosophy than agronomy — and the worst cut of all — lacking in “sound science.” Not anymore. Organic is pushing back one peer-reviewed research paper at a time. “We can claim science and we are,” declared Ralph Martin at the opening of the first Canadian Organic


Drought adds to Portugal’s economic woes

After Portugal’s driest February in 80 years, farmers are praying for a miracle as drought ravages pastures and sparks forest fires, exacerbating the country’s economic crisis. Worse still, official forecasters expect the freak weather pattern to prevail at least through the end of March, which would worsen a drought now classified as severe and extreme



New products must pass the “smell” test

Jeff Schoenau gets a variation of the same questions several times a year — on the phone, over coffee, via email or somewhere on the winter meeting circuit. “They basically all want to know, ‘What do you think of product XYZ?’” the University of Saskatchewan soil fertility specialist says. That can be a tough question

Glossary of garden terms

As we look through those seed catalogues and plan for a new season, here’s a list of terms to brush up on: Acidic soil: has a pH below seven, typical of clay soils. Azaleas, camellias, dogwoods and roses like acidic soils. Alkaline soil: has a pH of seven or higher. Annual plant: lives one year


Farm group wants common sense applied on winter fertilization ban

Manitoba should lift its recently introduced winter fertilizer application ban to allow for more flexibility with changing weather and corresponding soil temperatures, say members of the Keystone Agricultural Producers. The year-old nutrient management regulation prohibits application of nitrogen and phosphorus between Nov. 10 and April 10, and that means farmers may not be able to

Aiming for the “sweet spot” with phosphorus

Using low rates of phosphorus fertilizer is good for the environment and the farmer’s bottom line. But cutting corners too much can affect yields and impact long-term soil fertility, said John Heard, a soil fertility specialist with the crops branch of Manitoba Agriculture, Food and Rural Initiatives. “There’s really only four rates of phosphorus application:


The real dirt on variable-rate technology

Variable-rate technology is based on a simple premise. “Basically, we’re aiming for the right rate at the right place in the field,” Ross McKenzie, a soil scientist with Alberta Agriculture, told attendees at the Agronomy Update event in Red Deer. That starts with knowing your soil, but that’s a lot harder than most people think,

Wet soil and nitrogen don’t mix, says expert

Annoyed that you have to fork over more cash to replace lost fertilizer nutrients from last year’s flood? It could be worse, says Tom Jensen, Northern Great Plains regional director of the International Plant Nutrition Institute. On Manitoba’s relatively youthful soils deposited by glacial activity about 9,000 years ago, potassium is abundant. Farmers here apply
