Urea is a white crystalline substance with the chemical formula CO(NH2)2; it is highly water soluble and contains 46% nitrogen. Urea is widely used in fertilisers as a convenient source of nitrogen and supplies more nitrogen per ton of product than any other dry fertiliser. Also commonly used in the winter as a deicer / ice melting product for treating roads, paths, parking areas, driveways etc.

Urea has over twice as much nitrogen as does ammonium sulphate; 46% versus 21%. That means there is more than twice as much nitrogen per ton of fertilizer. In addition, urea is less acid forming, is more water soluble and less corrosive. Ammonium sulphate does supply sulphur, but it is usually less expensive to apply urea and elemental sulphur.

For lawns / grasslands urea should be applied at a rate of 2lbs per 1000sq ft (approx 1kg per 100sq m).
Apply when grass is dry and water in well after application. This will help to prevent any burning of grass. It is also recommended to water are each day after application for 2 or 3 days.
