The Agronomists, Ep 84: Derek Flad and Johanna Lindeboom on fertilizer BMPs


Using best management practices (BMPs) with fertilizer management is all about making sure the nutrient is available to the plant while minimizing movement out or off the field, via air, water, or soil movement.

To tackle what a fall-focused BMP might look like for phosphorus and nitrogen, host of The Agronomists, Lyndsey Smith, is joined by Derek Flad of Nutrien Ag Solutions, and Johanna Lindeboom of Clark Agri Service.

This episode of The Agronomists is brought to you by ADAMA Canada, Decisive Farming, and the Wheat School.

  • BMPs talk
  • Phosphorus was one of the first things farmers cut off this spring. Not because of recommendations, because of prices
  • Unless you are in livestock, chances are, your phosphorus levels
  • We need phosphorus as close to the rooting system as possible, so when applying, this needs to be a consideration
  • In Western Canada, for the most part runoff isn’t a concern
  • PLANNING. Plan your phosphorus applications. Keep records. Look into the past, and look into the future.
  • How much does soil type play into phosphorus response?
  • More and more people are making BMP’s a part of their operation
  • Do we give the same consideration to dry products as we do for liquid?

CLIP 1: Soil School: Keeping phosphorus on your farm

  • When your soil blows, it’s the good stuff that goes with that. Keeping that soil put should be a part of your fall plan
  • If we are looking at cover crops, what are our goals, and what are our realistic expectations
  • Logistics and agronomy are a never ending battle
  • What might impact our phos loss?
  • We have to look at what percentage we are fertilizing for.
  • We want to get nitrogen down early if we want to chase that maximum yield
  • There is such a thing as too early of fall applied N. But it certainly varies by soil type and temperature

CLIP 2: Wheat School: Are EEFs the way to protecting nitrogen loss?

  • Nitrogen is very prone to loses. One of the considerations is an enhanced efficiency fertilizers (EEFs).
  • You need to know where an EEF fits into your operation before taking the leap
  • Keeping those volatilization numbers low is key
  • Nitrification inhibitors are primarily used in the spring
  • Reduce the risk!
  • EEFs do not replace 4R nutrient stewardship. Please keep those 4Rs in mind! (Right rate, right time, right source, right place)
  • Make sure you fit the right product to the right scenario
  • Fertilize for your expectations, based on rotation
