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…

Canola fields may benefit from a top-dress application of nitrogen or sulphur (or both) if logistics and weather prevented the full recommended application of fertilizer at or before seeding, and if improved weather conditions (rainfall, for example) have increased the yield potential of the crop…

You don’t seed canola without starter phosphorus in the seed row, especially in cold soils, but you have options for the rest of the nutrients. And seed placement is not on the list…

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…
