Wheat yields pushing 150 bu/ac are very possible with good management and increased nitrogen (N) rates. Recent research clearly shows an interaction between fungicides and nitrogen. But high nitrogen rates immediately raises questions about lodging, nitrogen source, and application timing. Whe... Continue reading
In order to mitigate risk of dust exposure to bees, Ontario stakeholders believe that practical initiatives to reduce dust released during planting should be considered. This includes the use of an improved seed lubricant and the use of planter deflectors, in order to minimize pollinator exposure.

We are looking for OSCIA members who are interested in planting on-farm strip trials of neonicotinoid and fungicide only corn seed this year. Key objectives include: 1) gaining a better understanding of where the important soil insects are in Ontario corn fields so that we can develop high risk ma... Continue reading
Results of a variable rate corn population trial in Oxford County conducted during the 2013 season are presented below. In an earlier post we talked about the importance of reviewing as-applied maps. This field had several years of historical yield data which over time can be used to create manag... Continue reading

Protecting water from manure nutrients would be a lot easier if the weather would cooperate.
Most produers know that applying manure on snow or on frozen ground is a bad idea. Nutrients don't end up where they are needed and more money is spent on compensating with commercial fertilizer.... Continue reading
With higher yields, forage inventories have been increased to more normal levels. Hay inventories carried over in the spring were extremely low, and hay prices peaked at historic highs, before softening after first- and second-cuts. Haylage and baleage inventories and quality are very good. Earl... Continue reading
