A beautiful stand of red clover can provide as much as 75 kg of nitrogen per hectare (when at 40 cm tall) for next years corn crop. However, if the clover crop is not “killed off” in the fall, then preparing a suitable seedbed to plant next years crop in is often significantly delayed resulting in reduced yields. A review…
Albert Tenuta September 14, 2012 2472 Comments Off on First Confirmation of Soybean Vein Necrosis Virus in OntarioThe University of Guelph Pest Diagnostic Clinic confirmed this week Soybean Vein Necrosis Virus (SVNV) infection in soybean plants OMAFRA collected in Kent and Elgin counties last week. SVNV is a new soybean disease which was first identified in Tennessee in 2008. Since then the disease has been reported in many other States and most recently in bordering Great Lake…
Compiled by Chris Brown, edited by Horst Bohner 2012 Soybeans were originally introduced to Ontario as a forage crop for cattle. Today, the vast majority go for crush and the IP market. Letting the crop mature and harvesting the seed is far more profitable than using it as a forage crop but in some cases forage soybeans may be an…
OMAFRA Field Crop Team September 11, 2012 5696 Comments Off on Seed Placed Starter Delivers in Winter WheatOntario research shows an average of 7.5 bushels more wheat. Add in improved winter survival and a more uniform stand and you have an agronomic no-brainer. Stooped over a seed trench late at night, squinting through the beam of a flashlight at dark grey soil, Alan McCallum still doesn’t doubt how worthwhile starter fertilizer is for a wheat crop. In…
Farmers exposed to silo gas (nitrogen dioxide, NO2) are at risk of severe respiratory distress, permanent damage to lungs, and even sudden death. It is difficult to predict when silo gas will be produced, so always take precautions following harvest. Weather conditions and agronomic practices affect the amount of nitrates in plant material, which set the stage for the production of NO2 in…
Since it was first identified in Ontario in 1988, soybean cyst nematode (SCN) has been identified in most counties west of Toronto and more recently in parts of Eastern Ontario. The disease can be managed effectively, but the first step is identification and awareness. Losses to SCN in Ontario have ranged from 5%-100%. Unfortunately, by the time SCN symptoms become visible…
