Application:

1. Urea is a kind of high concentration nitrogen fertilizer, which belongs to the neutral quick effect fertilizer and can also be used for the production of various compound fertilizers.No harmful substances remain in the soil, and long-term application has no adverse effects.Animal husbandry can be used as feed for ruminants.

2. Urea is organic nitrogen fertilizer, which is hydrolyzed into ammonium carbonate or ammonium bicarbonate through the action of urease in soil before being absorbed by crops.Therefore, urea should be applied four to eight days before the fertilizer period of the crop.

3. Urea is used as base and topdressing, and sometimes as seed fertilizer.

4. Urea (nitrogen fertilizer) can promote cell division and growth, so that the branches and leaves grow luxuriant.
