AbstractN-Gold "A" and N-Gold "B" are granulated products containing urea and calcium oxide with 42.4 and 43.2 % N and 1.5 and 1.3 % Ca respectively. When broadcast onto soil or a green cane trash blanket, ammonia volatilisation losses were not different to those from prilled or granulated urea when tested in the maboratory. These products produced a more alkaline solution than urea and, in theory, this would slightly increase the ammonia volatilisation losses, but this did not happen in this experiment.N-Gold "A" and N-Gold "B", when analysed for N content in 0.5g samples, showed more variation than for the prilled or granulated urea. This variation is unlikely to cause any deleterious effects when used as a fertiliser but could have implications for quality control
