In-Crop Nitrogen efficiency

4 July 2018

Cropping and livestock producer at Mundulla Ian Pfitzner shares his experience with using a carbon source (BioMAX Fulvic Liquid or Powder) to reduce burn from high rate nitrogen applications in crops and pasture.

"I have used high rates of UAN, up to 70 L/ha in previous years. 

I always use Fulvic, powder or liquid to minimise leaf burn, and have found this to be most effective. 

This year I have applied 40 L/ha with Fulvic which softens the tank mix and allows easy uptake by the crop or pasture."

How does the addition of a 'Carbon' source with Nitrogen applications give a Return on Investment?

  1. Minimise leaf burn so that plant growth is not adversely affected by high nitrogen rates
  2. Better plant uptake as a good carbon source will improve the ability of plant leaf and roots to take up the nitrogen
  3. Improve nutrient efficiency - carbon source will hold nutrients available in the root zone for longer (reduce leaching and loss to atmosphere)
  4. Increase Yield and Improve Grain Quality - check out this report from an independent Peracto Trial on Nitrogen Efficiency in Wheat at Tarlee SA Trial Report
  5. Tip: Spray applications are best timed when plants are not under stress e.g. post frost
