Feed the crop that feeds the livestock!

OMAFRA Field Crop Report for the week ending September 4

For forage producers, the production year starts in the fall. What farmers do from mid-August to the end of the growing season impacts this winter’s feed inventory and next year’s forage yield potential. Forage crops have the highest crop nutrient removal values of any field crop grown in Ontario. Harvesting the whole crop while it […] Read more

Smoky haze over a wheat field late June, early July in 2023.

The potential impacts to field crops from wildfire smoke

OMAFRA Field Crop Report for the week ending August 30

Smoke from northern Ontario and Quebec wildfires was prevalent across Ontario for several weeks in June and early July. While a smoky haze was often visible during these weeks (see photo above), the heaviest days carried a campfire-like smell and reportedly even reduced visibility in parts of Northern and Eastern Ontario. What is the impact […] Read more

What to do with those stubble fields now? Consider BioStrip Till

What to do with those stubble fields now? Consider BioStrip Till

OMAFRA Field Crop Report for the week ending August 23

Winter wheat combining has almost wrapped up across the province after a challenging harvest due to persistent rainfall. There is a lot of enthusiasm for wheat across Ontario as yields were good to excellent and quality was good. Now, what to do with the wheat stubble? If you have manure, now is the best time […] Read more

OMAFRA has published a wide variety of publications with a crop production and protection information.

What’s in your crop decision-making toolbox?

OMAFRA Field Crop Report for the week of August 14

It’s the middle of August and we’re in that awkward lull where cereals are off, the last passes of fungicides on soybeans are done and it is almost time to start attending all those in-field plot days. Those days are meant to get producers talking, asking questions and get the thought process started for the […] Read more

Figure 1. Good soil structure (a, left) vs. poor soil structure (b, right).

Identifying and addressing soil structure challenges

OMAFRA Field Crop Report for the week of August 7

A well-structured soil improves water infiltration, air exchange, rooting, and ultimately crop yield. On the other hand, a cloddy, dense, or compacted soil may result in ponding, nutrient losses, and restricted root systems. Poor soil structure contributes to lower crop yields, especially in seasons that are either too dry or too wet.  In this article, […] Read more


Cover crop biomass harvested from a 0.25m2 area for tissue analysis.

Managing cover crop nitrogen, residue breakdown

OMAFRA Field Crop Report for the week of July 31

Across Ontario, wheat harvest continues, opening the best window for planting cover crops in most field crop rotations. You can find more information on the  2023 winter wheat quality update and achieving success with cover crops after wheat at fieldcropnews.com. But can those cover crops be managed to supply nitrogen to the next crop? The amount of nitrogen […] Read more

Spider mites bugging your soybeans?

OMAFRA Field Crop Report for the week of July 3

Dimethoate resistant two-spotted spider mite populations in Ontario soybeans Results from bioassays conducted on two-spotted spider mite (TSSM) populations collected in soybean fields across Ontario show the prevalence of dimethoate (Cygon or Lagon) resistance is high in some areas. Through a collaborative project with Dr. Vojislava Grbic, Professor at Western University, Dr. Ian Scott at […] Read more

Tar spot injury on corn.

Time to watch for tar spot, soybean cyst nematode

OMAFRA Field Crop Report for the week of June 26

Tar spot has now been established in the midwestern US for almost a decade and is an annual concern in many Midwestern states like Illinois, Indiana, Iowa, Michigan, and Wisconsin. While tar spot was not as yield-limiting in these areas in 2022, it continued to expand its range across the corn belt, as far west as Kansas […] Read more

Cereal crops parched, fears of spontaneous combustion in hay

OMAFRA Field Crop Report for the week of June 5

Field conditions across most of the province are drier than normal. This generally will have little effect on corn and soybeans since both are at the early vegetative growth stage. The impact on winter cereals could be significant since they are already out in head and at, or nearing, pollination. Forages There is an unusually […] Read more
