The start of this week has been marked by several days of well above normal temperatures – daily highs in the low to mid 30’s brings the first summer-like hot spell across much of Ontario. These temperatures have helped reduce the heat unit deficit that has been a hallmark of spring 2025. Field Corn Very […]
The province experienced weather extremes. Southern Ontario saw warmer conditions that supported corn and soybean growth and helped dry fields still awaiting planting. However, wind and scattered rain complicated weed control efforts. In the Northeast and Northwest Ontario, temperatures neared 0°C, raising concerns about frost damage to emerged soybeans and white beans. Field assessments are […]
A cooler than average start to the growing season has added some uncertainty to post-plant nitrogen fertilization strategies for Ontario corn producers. Soil supply of nitrogen to the corn crop is likely lower than normal due to reduced N mineralization from both soil organic matter and manure, and the Maximum Economic Rate of Nitrogen (MERN) […]
It’s been a tough spring across much of Ontario and growers continue to face variable weather conditions, creating both opportunities and challenges across regions. Frequent rain events have delayed planting in parts of eastern Ontario, particularly on heavier clays from Belleville to Kingston and Essex which had up to 3” of rain last week halting […]
Soybeans Soybean planting is largely complete on lighter textured soils and well drained fields. Planting is still underway on heavy soils and in regions of the province that continue to receive sporadic rainfall. Cool temperatures during April and May have slowed emergence, with fields taking longer to emerge this year. With warm weather, soybeans typically […]
Have you been seeing increased corn rootworm pressure in your continuous corn fields over the last few years? Monitoring with sticky traps can help you determine if you have a Bt resistant corn rootworm problem and it helps us keep track of where these problem fields are. Thanks to GFO and ABSTC, we still have […]
