Current New Zealand dairy production could be very considerably increased, with only half the current amount of fertiliser urea being used, if granular urea was replaced with ONEsystem(R) the use of wetted, prilled urea incorporating the urease inhibitor nbpt. Total cost to the farmer would fall dramatically, with the halving of urea costs, and the same or marginally higher spreading costs. Losses to the environment would be greatly reduced, as any input into Overseer® will quickly confirm.
The urine-N leaching problem can be solved with the Spikey(R) technology, avoiding capital-intensive cow homes. The ONEsystem(R) and Spikey(R) technologies can be easily combined, at a total treatment cost less than just using granular urea to reach a certain level of production. A real win-win outcome.
