Specification

Product Characteristics:

1. High nitrogen content: 46.0-46.4%, which is the highest level among the solid nitrogen fertilizer.
2. Easily soluble in water, with stable physical and chemical properties and low hygroscopicity before manuring into the soil. It is an effective nitrogenous fertilizer with stable commercial shape.
3. Urea is a neutral fertilizer and widely suitable for various soils and crops. After nitrogen is absorbed, the remaining carbonate can still help the other water-insoluble ingredients to dissolve and turn into active ones.
4. The fertilizer effect of Urea is slower than that of ammonium nitrogen fertilizer, so urea needs to manure in advance in case of top-dressing application.

Application scope:

1. Industrial application: Used as the material for producing certain industrial products such as melamine, urea-formaldehyde resin, cyanuric acid and plate glue, as well as the feed additives for ruminants.
2. Agricultural application: Urea is suitable for all kinds of crops and soils; it can be applied as base fertilizer and top dressing in dry farmland or paddy field.

Usage:

When applied as topdressing, urea can be manured to crops root in soil, as well as foliar spraying.

In case of soil topdressing during crops growth boom period, make sure to manure earlier than the quick-acting fertilizer such as ammonium sulphate, ammonium bicarbonate etc.

The time in advance depends on seasons and temperature:

6~8 days in advance during early spring (10℃);

3~4 days in advance during late spring and early summer (16-20℃);

1~2 days in advance during summer.

As topdressing applied to the crops root and foliar spraying, the appropriate concentration is usually 0.1-0.5%, which varies from crop species and growth period.

Please make sure that the content of biuret must be less than 0.5% when urea is applied to foliar spray.

Besides, when the mixture of urea and potassium dihydrogen phosphate is applied as foliage topdressing, it shall be sprayed on leaves of the crops such as wheat and corn etc.
