Achieving success with cover crops after winter wheat

With winter wheat harvest beginning in parts of the province, cover crop seeding will be close on its heels. Adoption of cover crops has increased in Ontario over the last number of years, and for good reason – they help improve water infiltration, compete with weeds, and capture left-over nutrients. In this article, I’ll share […]

Nitrogen losses in saturated soils

Recent rainfalls have brought about an abrupt change to soil conditions in some Ontario fields in just a few short weeks ago.  Localized heavy rainfalls have left some fields with standing water in low-lying areas, while many fields are wet or saturated.  This has raised questions about the potential losses of nitrogen (N) for the […]

Crop Report – Week of July 3rd, 2023

Levels of dimethoate effectiveness in two-spotted spider mite populations collected in 31 soybean fields in 2021 and 2022.

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 […]

What does 2023’s Weather Tell Us about Anticipated Soil Nitrogen Supply?

Summary Background Throughout the growing season, microbes within the soil break down organic nitrogen contained in soil organic matter and release it as plant-available ammonium.  This process is known as nitrogen mineralization. Nitrogen mineralization is favoured by warm soil temperatures with adequate soil moisture and aeration.  Excess moisture can slow mineralization or increase the potential […]

When do cover crops, with and without manure applied, release nitrogen that can be used for my corn crop?

Cover crops can produce nitrogen. We looked at when different species release nitrogen and the impact that adding manure has on the timing and release of nitrogen. The simple answer Predicting nitrogen (N) availability from cover crops is complicated. Cold and wet conditions in the spring negativelyimpact soil microbial activity and can result in significant […]

Preventing and Extinguishing Hay Fires

Key Points: What Causes Fires? The process of forage heating up and then burning is typically called spontaneous combustion. Spontaneous combustion for hay usually occurs within the first two months of storage. Unusual growing conditions, such as an early harvest window or immature crop, can complicate the drying process and increase the risk of fire. […]
