Urea (chemical formula CO (NH ₂) ₂) is an organic compound composed of four elements: carbon, nitrogen, oxygen, and hydrogen, with a nitrogen content of up to 46.65%, making it the nitrogen fertilizer with the highest nitrogen content. Its physical properties are white crystals, easily soluble in water, and highly hygroscopic; The chemical properties are stable, but it will decompose into ammonium cyanate or biuret at high temperatures.
Agriculture: Urea is a high concentration nitrogen fertilizer, a neutral and quick acting fertilizer, and can also be used to produce various compound fertilizers. No harmful substances remain in the soil, and long-term application has no adverse effects. Urea is suitable for use as base fertilizer and topdressing, and sometimes also as seed fertilizer. Urea is in a molecular state before conversion and cannot be adsorbed by soil. It should be prevented from being lost with water. After urea is applied to the soil, a small portion of urea dissolves in the soil solution in molecular form and is adsorbed by the soil through hydrogen bonding. The rest is hydrolyzed into ammonium carbonate under the action of urease, which then generates carbonic acid and ammonium hydroxide. Then ammonium ions can be absorbed by plants and soil colloids, and bicarbonate ions can also be absorbed by plants, so there are no harmful components left after urea is applied to the soil.
