Do I need to apply sulphur to winter wheat?

April 3, 2013 • Written by Peter Johnson
Wheat_starter
According to Environment Canada, atmospheric sulphur dioxide emissions were reduced by over 50% from 1990 to 2010. Although this is a positive outcome for emissions reductions it does signal an inevitable need to ensure that field crops have an adequate supply of this essential nutrient. A study was...

ESN Controlled Release Fertilizer on Spring Wheat

April 2, 2013 • Written by Scott Banks
Does ESN pay in spring wheat? Results from two on-farm sites in eastern Ontario showed no advantage in grain yield or protein content with the use of ESN in 2011 (see Table 1). There was also no significant difference in residue soil nitrogen levels. As expected there was also no impact in the perce... Continue reading →

Getting Started with Variable Rate Nitrogen

January 16, 2013 • Written by Nicole Rabe
Topographic Zones Red is high (1020-1050ft), orange are side slopes, Green is low (970-980 ft)
When you don't have the luxury of starting with multiple years of corn yield data how does one get started with a variable rate nitrogen strategy? Initial assessment of the field needs to question how variable the field actually is, and more to the point - what is driving the variability across that... Continue reading →

Fall Control of a Red Clover Cover Crop

September 27, 2012 • Written by Mike Cowbrough
Fall Control of a Red Clover Cover Crop
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 ... Continue reading →

Seed Placed Starter Delivers in Winter Wheat

September 11, 2012 • Written by OMAF Field Crop Team
Seed Placed Starter Delivers in Winter Wheat
Ontario 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... Continue reading →
