The tracing experiment results show that the NUEs of urea at application depths of 8 cm, 16 cm and 24 cm are 37.24%, 31.33% and 18.75% respectively. After the maize harvest, the N residual in the 0-100 cm soil layer under the N24 treatment is significantly higher than those of the N8 and N16 treatments.

Urea is a hot concentrated solution produced by the reaction of ammonia with carbon dioxide. When dissolved with water, this concentrated urea hot-melt liquid becomes an aqueous urea solution or a feedstock for the prilling or granulating process. Prilled urea is used for the technical grade urea market for industrial applications.

Urea, a white crystalline solid is a most concentrated solid nitrogenous fertilizer, containing 46% nitrogen and is most popular fertilizer in the agriculture industry. Urea is a synthetic organic compound which can be applied to soil as a solid or by fertigation and to certain crops in limited concentrations it can also be applied as a foliar ...

The urea solution can be used as an ingredient of nitrogen solution fertilizers, or it can be concentrated further to produce solid urea. The 3 methods of concentrating the urea solution are vacuum concentration, crystallization, and atmospheric evaporation. The method chosen depends upon the level of biuret (NH2CONHCONH2)

The standard crop–nutrient rating of urea is 46–0–0. The most common impurity of synthetic urea is Biuret, which impairs plant growth. Urea is usually spread at rates of between 40 and 300 Kg./HA but rates vary. Smaller applications incur lower losses due to leaching. During summer season, Urea is often
