N-Hydroxyphentermine CAS NO.38473-30-2

Urea is a chemically synthesized organic amide nitrogen fertilizer. Because of its high nitrogen content, good physical shape and no side components, urea has become the highest nitrogen fertilizer in the world. Urea molecular formula is (NH2) 2CO, nitrogen 46%, white crystal or particle, easily soluble in water, aqueous solution is neutral. Hygroscopic, not easy to caking, basically not decomposed at room temperature, but in the case of high temperature and high humidity climate, will also be hygroscopic caking, storage and transportation should pay attention to moisture.It has strong hygroscopic property, keeps the leaves wet after spraying, and absorbs fast. Therefore, whether old leaves or young leaves; Or soft or hard leaves can absorb well. Although the nitrogen content is high (46%), there is generally no toxic effect on fruit trees after spraying.
