Post wheat harvest weed management strategies

OMAFRA Field Crop Report for July 30

Reading Time: 2 minutes The establishment of cover crops after cereal harvest has been shown to reduce weed seed production and dispersal to the soil. This is of particular benefit when trying to manage glyphosate resistant weed species like Canada fleabane and waterhemp (a relative of redroot pigweed). Some highlights from recent studies include: Fall planted cereal rye on […] Read more

Harvested fields a good time to improve soil health

OMAFRA Field Crop Report for July 23

Reading Time: 3 minutes Harvested wheat fields offer the perfect opportunity to focus on improving soil health. Planting cover crops and/or applying manure or other organic amendments provides soil microbes with the carbon compounds that help create a more porous soil structure which improves water, air and nutrient cycling. Here are a few common questions that come up every […] Read more
