In 2016 clubroot (Plasmodiophora brassicae) was detected in fields across Ontario. The results of a preliminary survey for clubroot of canola in Ontario was posted previously on Field Crop News; to review it Click Here. This article provides more information on the disease and how to manage it. You can learn a great deal more about […]
Crop yields have increased significantly since fertility recommendations were developed in Ontario. Crop nutrient uptake and grain nutrient removal have increased proportionately. A study was initiated in 2011 with funding from the Grain Farmers of Ontario to evaluate a corn-soybean-wheat rotation on four sites with relatively low soil test P and K levels. Areas within […]
Previously we discussed the possible benefits of using a pre-emergence soil applied herbicide application in a 2-pass weed management plan. Those benefits include protecting yield, providing a wider window for a post-emergence application and as a resistance management strategy. In this installment we look at the effect of weed emergence, following a pre-emergence application, on […]
We’re excited to let you know about the latest updates that we made to the Agricultural Information Atlas (AIA). What is the AIA? It’s OMAFRA’s free, easy-to-use online tool that can help you to: Develop nutrient management strategies and plans Plan tile drainage for your farm Develop a farm sketch for Pest Assessment Reports and Bee […]
Volume 1 of the inaugural “Problem Weed Guide for Ontario Crops” includes management strategies for 19 species in corn, soybean and cereal crops that is cited from work conducted by the University of Guelph Department of Plant Agriculture as well as other peer reviewed studies. This 176 page guide features over 175 images and 50 […]
Sulphur (S) deficiency was very prevalent in winter wheat last spring, including fields with a history of manure applications (Photo 1). The deficiency seen in many fields may have resulted from a cooler than normal April reducing S mineralization. S applications may not be required every year due to the year to year variation in response […]
By Joey Sabljic Past articles in our Understanding Precision Agriculture series have focused on the main pieces — data collection, management zone creation, and prescription mapping — that form the foundation of a successful precision ag approach. This month, we spoke with three growers who have been involved with the Precision Agriculture Advancement for Ontario (PAAO) […]
Cover crops are well proven to help reduce soil erosion and improve soil structure. They can also have nutrient benefits. Whether you have been growing cover crops for decades or are just getting started, it is helpful to know what specific cover crops can (and cannot) do from a soil fertility standpoint. There are three […]
