At least one scientist will tell you it's none of the above — the most limiting factor for crop production in North America is actually soil carbon. "Our soils are starved for carbon," says Kristine Nichols, a... Read More

Growing Degree Days (GDD) are an indicator of expected crop development based on weather conditions. GDDs are calculated by taking the mean temperature over a day and subtracting a base temperature. For most cereal grains, the base temperature is considered 5 degrees C, as they require around 1200 GDD to reach maturity. GDD = (Tmax... Read More

The importance of good spray coverage is emphasized in all kinds of agricultural publications, including product labels. But, according to Tom Wolf, spray application specialist with AgriMetrix Research and Training in this episode of Spray Tips, "the labels are remarkably silent on what good coverage actually is and how you can actually measure it."

Good forage makes money, but poor forage is money lost. Tom Kilcer, of Advanced Ag Systems in Kinderhook, NY, has spent years researching forage production, forage quality, and livestock performance. Here’s what he’s learned. Contrary to common assumptions, forage does not dry by the same mechanisms from start to finish. They are, in fact, three... Read More

This week, Winnipeg, Man., hosted the World Congress on Conservation Agriculture — a three day event that brought together research and extension staff with farmers and industry to discuss the state of conservation agriculture all over the world. Conservation agriculture, a combination of zero-tillage, cover crops, extensive crop rotation and more, looks very different from... Read More
