"Why are so many farmers using or switching to Urea fertilisers?"

Q: Does Urea lose appreciable amounts of ammonia to the atmosphere when applied?
A: No. In most application conditions and soil types, any atmospheric N loss is nominal and no more than with AN. The only conditions of any significance where nitrogen loss may be measurable are on very sandy or light chalky soils, when Urea is dressed onto moist soils and followed by over two weeks of warm and dry weather.

Q: Is Urea slow releasing?
A: No Urea is very soluble and dissolves even faster than AN. Urea is one of the most natural sources of Nitrogen available for use as a fertiliser, produced chemically by combining ammonia and carbon dioxide. When applied to the soil, Urea is converted to ammonia carbonate and the bacteria in the soil convert the ammonium to nitrate-nitrogen.

Q: Does Urea have a higher density compared to AN?
A: No. Not in respect of the amount of nutrient in each 500kg bag. Each 500kg bag of Urea contains 460 units of N (230 kg/N), compared to 345 units of N (172.5kg/N) in a bag of N.

Q: Are the application rates of Urea different to AN?
A: Only in respect that each 50kg bag applies 46 units (23kg) of N compared to a bag of AN applying 34.5% units (17.25kg) of N. Therefore application rates usually used when applying AN, should be reduced by 25% for Urea application.

Q: Does Urea store over a season?
A: Urea has excellent storage characteristics, even in bulk. The products are coated with an anti-caking agent and the quality should not deteriorate through lengthy storage. Bulk area represents even higher savings, and when stored forms a thing protective casing. All fertilisers must be stored under cover and in dry conditions.

Q: Does Urea spread as well as other fertilisers?
A: Using the correct calibrated spreader for the recommended Urea type, Urea spreads accurately. Recent spreader trials on granular Urea to bouts of 24 metres produced a very low coefficient of variance of 7%.

Granular Urea is a premium quality product with a low cost per unit of N. The granulometry and density are adequate for broadcasting application bouts of up to 24 metres. Granular Urea arguably has sufficient characteristics to spread as well as any other production on the market.

Prilled Urea is ideal for broadcasting up to 12 metres or application through pneumatic type spreader. Prilled product is most suited for use in liquids.
