Urea Form : Granules

Urea is a high-concentration nitrogen fertilizer, 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. Animal husbandry can be used as feed for ruminants. Urea is an organic nitrogen fertilizer. After being hydrolyzed into ammonium carbonate or ammonium bicarbonate by the action of urease in the soil, it can be absorbed and utilized by crops. Therefore, urea should be applied 4 to 8 days before the fertilization period of the crop.Urea is suitable for base fertilizer and top dressing, and sometimes as seed fertilizer. Before conversion, urea is in a molecular state and cannot be adsorbed by the soil. It should be prevented from being lost with water; the ammonia formed after conversion is also volatile, so urea should be covered with soil deeply. Urea is suitable for all crops and all soils, can be used as base fertilizer and top dressing, and can be applied in dry paddy fields. Because urea can accumulate a large amount of ammonium ions in the soil, it will increase the pH by 2-3 units. In addition, urea itself contains a certain amount of biuret. When its concentration is 500ppm, it will affect the roots of the crops. Young shoots have an inhibitory effect, so urea is not suitable for seed fertilizer.Urea (nitrogen fertilizer) can promote cell division and growth, making branches and leaves grow luxuriantly.
