Nitrogenous fertilizer, readily soluble in water, alcohols and liquid ammonia. It takes the form of white prilled, grain class 1-3.15 mm, with at least 90% of the prills covered with anti-caking agents. Prilled urea 46% is hygroscopic. Bulk density: 0.70-0.78 kg/dm3. Prilled urea 46% includes 46% of nitrogen (N) in ureic form, easily absorbed by the leaves of plants. Absorption through the root system is slower, because urea in soil is converted (as a result of enzymatic hydrolysis) into the ammonia form available for plants, and then into nitrate form.
