Wet Soils, Yellow Crops and Options for Midseason Applications of Nitrogen Fertilizer

With the large rainfall events across many parts of Manitoba recently, some farmers are noticing yellowing in their crops and wondering if they should top up their fields with some more nitrogen fertilizer. Unfortunately, there are no easy rules to follow or large experimental datasets to refer to for making this type of decision.

The attached article by Dr. Don Flaten, University of Manitoba, and John Heard, Manitoba Agriculture, outlines some principles if considering midseason application of nitrogen fertilizer.

Wet Soils, Yellow Crops and Options for Midseason Applications of Nitrogen Fertilizer – June 2016

And remember….the first issue to consider is whether the crop yellowing is from N deficiency or simply flooding stress due to excess water. Applying N fertilizer onto crops that are suffering primarily from flooding stress could be a poor investment.

Assessing Crops After Heavy Rains

Compiled by the Staff at Crop Industry Branch, Manitoba Agriculture

Some areas of Manitoba received heavy rainfall recently, resulting in the question “What is the extent of crop damage from the heavy rains?”  There is no quick answer unfortunately.  Field by field assessments over the coming days will give a better idea of what impact the rains had on crop development and plant stands. The following link can provide an idea of what is potentially occurring and how to monitor fields to assess for damage and recovery.
