A University of Guelph researcher has received government funding to help Canadian farmers grow wheat using fertilizer more efficiently while strengthening soil health and the wheat microbiome. Dr. Kari Dunfield…
What’s the most economic rate of nitrogen for corn? Where is that line between feeding the crop the right amount of the yield-producing nutrient and wasting dollars on excess product?…
Nitrogen fertilizer use in agriculture has been increasing; unfortunately, the same is true for nitrogen losses to the environment. Weather, as well as the frequency and timing of nitrogen applications, can affect how efficiently nitrogen is used by the crop to produce yield and how much is lost. One way to improve nitrogen fertilizer use in corn is to split the application so that some is applied at planting and the rest is applied in the growing crop. Farmers can then adjust the rate and timing of the second application depending on the weather.
Using fertilizer efficiently is vital for managing agroecosystems sustainably. It makes the most of crop productivity while protecting the environment. As agriculture has intensified, the use of synthetic nitrogen (N) fertilizers has increased.
To till or not to till, if only there was an easy answer! Thankfully, a long-term research trial at the Ontario Crops Research Centre-Ridgetown can give us a place to start.
