The 4R panel at Canola Discovery Forum 2020 generated a lot of interest among attendees, which meant a lot of questions went unanswered. Fortunately, the panelists agreed to answer the questions after the fact. Here are answers to the unanswered questions…

Canola generally needs nitrogen, phosphorus and sulphur fertilizer each year. A small percentage of fields will also benefit from a potassium application. The following article suggests what canola needs and what soil and crop residue could provide. The rest will come from fertilizer…

A few days of warmer weather provide an opportunity to squeeze in some soil sampling. Soil tests are a basic practice of 4R Nutrient Stewardship…

The ideal timing for fertilizer application is at seeding, but there are times when an in-crop top up of nitrogen or sulphur makes sense. This article provides tips to make top dressing work in those situations… -
Tissue sampling can be used to diagnose crop problems that may be nutritionally related and to identify any nutrients that may be limiting yields…

Improved crop moisture may have improved the yield potential of canola crops. If nutrient availability does not match this new yield potential, in-crop top-dressing of nitrogen or sulphur (or both) could provide an economic benefit. Find out how to do it…

The most accurate sampling time is just prior to seeding, but this isn't always practical because time is needed to purchase and perhaps place the fertilizer before seeding. The next best alternative for this time of year is early spring sampling done after the soil has thawed and is no longer saturated from snow melt…
