Chemical name: Urea
Molecular formula: CH4N2O
1. Urea is a high-concentration nitrogen fertilizer, which is a neutral quick-acting fertilizer and can also be used to produce a variety of compound fertilizers. No harmful substances remain in the soil, and long-term application has no adverse effects.
2. Urea is an organic nitrogen fertilizer that can be absorbed and utilized by crops after being hydrolyzed to ammonium carbonate or ammonium bicarbonate by urease in the soil.
3. Urea is molecular that cannot be adsorbed by soil before conversion, so it should be prevented from losing with water. The ammonia formed after conversion is also volatile, so urea should be applied deep.
4. Urea conversion in soil can accumulate a large amount of ammonium ions, which will cause the PH to rise by 2-3 units.
Good quality and fast shipping. I ‘d buy from this shop again
