We've tabled the real cost of urea vs N-Protect

	Cost per kg N	Avg N loss*	Cost per kg retained N	Cost per kg DM
Urea	$2.93	18%	$3.57	$0.36
N-Protect	$3.05	9%	$3.35	$0.33

Assumptions: 18% average N-loss urea, 50% reduction N-loss N-Protect. 10:1 DM response. Pricing current as at 09/08/2022.

Choosing N-Protect over urea enables a reduction in DM cost per kilogram and (all things being equal) delivers the same amount of plant available N for less. Because N-Protect is also a coated urea fertiliser, it reduces N-loss to the atmosphere. A win-win for farming businesses and the planet.

Optimise nutrient efficiency

Research shows the risk of N-loss from urea spring to autumn averages 18%, unless 10mm of water falls within 8 hours.

n-protect losses are significantly less when compared to straight urea

N-Protect’s urease inhibitor coating reduces average N-loss to the atmosphere, slowing down the conversion of nitrogen to ammonia gas (ammonia volatilisation) by as much as 50%.

N-loss precision drives Waikato dairy operation’s vision

For Waikato dairy farm consultant Paul Lawrey, precision is particularly important when it comes to on-farm nutrient use.

Reducing N fertiliser without losing performance

Ravensdown has been involved in a DairyNZ project in Canterbury, looking into ways farmers can reduce N-loss and N inputs without sacrificing on-farm performance. Ravensdown Environmental Principal Consultant Arron Hutton and DairyNZ Farm Systems Developer Phillipa Hedley discuss some of their observations from the project.
