Use:Urea is a high concentration of nitrogen fertilizer, which is a neutral quick-acting fertilizer, and can also be used to produce many kinds of compound fertilizer.
No harmful substances are left in the soil.
No adverse effects can be found in long-term application.
However, the high temperature in the granule produces a small amount of biuret, which is also called biuret, which has inhibitory effect on the crops.
The content of urea biuret in fertilizer should be less than 0.5% in China.
When the content of biuret is more than 1%, it can not be used as fertilizer, fertilizer and leaf surface fertilizer, and the amount of urea in other application period should not be too much or too concentrated.
Urea is an organic nitrogen fertilizer, which can be absorbed by the crop after being hydrolyzed into ammonium carbonate or ammonium bicarbonate. Therefore, urea should be applied 4 ~ 8 days before the crop needs
