I took this video in 2010 when a lot of corn was planted in mid April and had emerged nicely only to be hit with a frost in May. Although the injury looked bad at the time, because the growing point was below the ground the crop made a complete recovery and 2010 saw record high provincial corn yield... Continue reading
Aftermarket planter modifications to control row unit down pressure have been well promoted into the Ontario marketplace, and are advertised for their ability to improve planter function, and final yields. The basic principles behind the modifications have merit, but the relative yield imp... Continue reading
With yield data and production information from across the province, the 2012 hybrid corn performance trials are a valuable tool for farmers when selecting seed for the upcoming season.
Produced by the Ontario Corn Committee, the report is available in an easy-to-download version that can be prin... Continue reading

The annual corn ear mould and vomitoxin survey by the OMAFRA Field Crops team indicates that the 2012 Ontario corn crop is distinctly low in ear moulds and vomitoxin. However, stakeholders are reminded that individual field conditions (environ... Continue reading
Corn development has been rapid this past week. Some areas were close to accumulating 200 CHU in 7 days! Good soil conditions and early planting are paying off as the corn continues to move ahead despite relatively dry conditions. Some replanting has occurred where low population and uneven st...

If you are unhappy with your stand of corn and think you may wish to replant, download the Ontario Corn Replant Calculator to assist you in this important decision. Many thanks to Dr. Dave Hooker and Ken Janovicek (Plant Agriculture Department, University of Guelph) for their efforts in putting this... Continue reading
Corn planting is essentially complete across Ontario other then a small amount of replanting due to emergence/stand issues or where corn is following first cut alfalfa. Use the Replant Decision Aid posted at www.gocorn.net if considering this where stands are thin. Start with accurate plant counts... Continue reading
Corn planting is 95 % complete across the province. Emergence is good to excellent in most areas with the majority of the corn in the 1-3 leaf stage. Weed control should be the priority as the crop approaches the critical 3-4 leaf stage. Cutworm injury has been reported in some areas south of London... Continue reading
Corn planting ranges from 50 to 95% complete; provincially corn planting is estimated at 80%. In most areas rainfall has not been intense and soils remain in good shape despite large acreages without significant residue cover. Corn requires about 180 CHU to emerge. Corn planted April 16-20 is ... Continue reading
Corn planting is 20-90% complete depending on the area of the province; provincially planting is estimated at 65%. Some of the early (i.e. April 5-15) planted corn had emerged and the cold temperatures of April 27, 28 & 29 froze the above ground tissue. However, to date, growing point and seed i...

Depending on the area, 10 to 60% of the corn crop has been planted. Provincially corn planting is estimated at 35%. Soil conditions remain dry and friable in most areas; the lack of soil moisture is an increasing concern and has forced deeper planting especially on light textured soils. Cold tempera...

Depending on the area, 5-30% of the corn crop has been planted. Soil conditions have been very good. Cool temperatures (especially at night) in the last week have slowed the emergence process. If drying trends continue growers are advised to be cautious with secondary tillage that is too aggressiv... Continue reading
Corn yield losses are huge if lower testing phosphorus (P) and potash (k) levels are detected on your farm. Here is talk I gave recently on approaches to starter fertilizer strategies based on the the type of equipment you have and different soil test levels.

You can click on the link below and it will take you to a 16 minute presentation that I gave recently on nitrogen management in corn. As we continue to push for higher yields in corn, there are some interesting variables that we will have to consider when trying to optimize economic rates of nitroge... Continue reading
There is lots of talk these days about crop residue removal for bioenergy purposes. We have gone through the first wave of trying to make it very clear to those less familiar with agriculture that this crop residue has real value.
Crop Residue Value Components
Crop residue value hinges on a few co... Continue reading
