Urée

Urea supplies 46% nitrogen in ureic form, as prills. In the soil, ureic nitrogen is converted into ammoniacal and then nitrate nitrogen, which roots take up: it is a high-analysis growth nitrogen fertiliser.

• 46% nitrogen (N): a high content, so little product to handle per unit of nitrogen
• Prills that spread evenly
• Growth nitrogen: supports leaf and vegetative development
• Limit losses: incorporate urea or apply it before rain or irrigation, to reduce ammonia volatilisation
• Precaution: do not place it in direct contact with seeds or roots
