Urea contains 46% nitrogen and is the most commonly used high-quality nitrogen fertilizer in production. However, the utilization of urea after it is applied to soil is usually only 45%-50%. So, how to increase the utilization of urea? Deeply. Urea, whether as a base fertilizer or as a top dressing, should be deeply applied to cover the soil, and the depth of fertilizer should be 10-12 cm. Urea deep application can significantly increase the utilization rate.æ¤ test, urea table or shallow application of 2-3 cm, the utilization rate is only 30%; fertilization depth of 5 cm, the utilization rate of 45%; deep Shi 10-20 cm, the utilization rate of up to 65%. Apply early. Urea belongs to Ammonium Ammonium Nitrogen Fertilizer and can not be directly absorbed and utilized by crops after being applied to the soil. It needs to be converted into ammonium nitrogen under the action of urease in soil to be absorbed by the root system. Too late application time is not only unfavorable to the exertion of fertilizer, but also may cause Crops are greedy and late. Foliar spraying. The urea molecule is small and easily absorbed by the leaves. It is the most suitable fertilizer for foliar spraying. Foliage spraying is highly targeted, fast in absorption rate, free from influence of soil factors, high nutrient utilization rate, low fertilization, and significant yield increase effect, especially in poor soil environment, excessive water or drought, soil acidity or alkalinity When the absorption of roots is impeded and the crop needs nitrogen nutrients and the root activity of crops declines at the later stages of growth, the use of foliar sprays can make up for the lack of root absorption. Used in conjunction with other fertilizers. Urea should be combined with organic fertilizers, phosphorus and potash fertilizers and trace element fertilizers to maintain soil nutrient balance, maximize nutrient utilization, and increase fertilizer production.
