Trial and error replacing 88% of our CAN with urea at Gurteen College
Initially, Ken Flynn, farm manager and lecturer at Gurteen College, said he thought the only benefit of protected urea over CAN was getting more nitrogen for less money, now it's replaced 88% of the farm's CAN. Picture: Dan Linehan
Our journey with protected urea started back in 2019. After being introduced to the idea, we decided to use it on one ten-acre paddock to replace the use of CAN fertiliser.
We had our first spreading of protected urea in May of that year, and after every grazing, we gave the paddock an application of protected urea. It was a 38%N product, and we spread 100kg per hectare of the product each time, which worked out at about 30 units N per acre per grazing.
