Phosphorus management is and must be a long term proposition. Phosphorus behaves very differently than nitrogen in the soil, as it binds tightly to soil particles and releases slowly over time. This is good and bad — it's not subject to the same loss risk that N is, but it also means that sometimes the... Read More

In this episode of the Corn School, Bernard Tobin and OMAF Corn Lead Greg Stewart turn to a chalkboard to draw up some nitrogen strategies for the 2014 corn crop. Throughout the winter meeting season, Stewart touted a split application approach to nitrogen. He recommends growers put down 100 lb of nitrogen pre-plant and then... Read More
As the snow retreats (quickly now, get on with you), it's time to get out there and take a good look at the winter wheat stand. There is such thing as doing a winterkill evaluation too early, but, depending on the method you use, you could need up to two weeks to get a good... Read More
It's early April and farmers are itching to get the planter out in the field. For the precious few of you in Ontario that are nearly ready to roll, have at 'er, but for most of the corn growing region, it's not late yet, but it's looking like the planting window may be slightly compressed....

Are you seeding your canola at 5lb/ac? Unless your seed rate was calculated based on that seed lot's thousand kernel weight (TKW), you may be losing yield potential, as plant numbers decline with increasing seed size. Angela Brackenreed, agronomy specialist with the Canola Council of Canada, suggests re-calibrating when the TKW of a seed lot... Read More
As Ontario cereal specialist Peter Johnson says, farmers aren't satisfied 'til they've (mentally) killed the winter wheat crop three times. So, it's no surprise then, that as the earliest fields are appearing from under the snow (sigh, alas, not yet in all areas), many farmers are concerned with how the crop looks and whether or...

Canola seed size has climbed in recent years from a once-common 4 grams per 1,000 kernel weight to north of 7 grams per 1,000 seeds. What does that mean to you, the farmer? It means that if you've stuck with your typical four pounds per acre seeding rate (and there are good reasons to do... Read More
From a distance, a nitrogen deficient canola plant and a sulphur deficient plant can actually look rather similar. It's only once you get up close and compare it to plants from other areas of the field, that you can better assess what's hampering growth of the crop. In this episode of the Canola School, Dan...

No two farmers manage their corn crop the same way, yet can achieve top yields. This is great news, because it means that no matter what your goals are for the farm, from decreasing tillage, to using more cover crops, there's a way to produce more corn per acre. That's one of the take-home messages... Read More
The impact of a frost on the canola crop is not likely to impact a field the same way twice. There are just too many variables at play — the temperature of the frost, the duration, the topography of the field, the growth stage of the plant, the soil moisture, trash cover and, perhaps most...
