Misunderstanding 1: Urea mixed with ammonium bicarbonate. Since urea is applied to the soil, it must be converted into ammonia before it can be absorbed by the crop. The conversion rate is much slower under alkaline conditions than under acidic conditions. After ammonium bicarbonate was applied to the soil, the reaction was alkaline and the pH was 8.2-8.4. Mixed application of ammonium bicarbonate and urea in farmland will greatly reduce the rate of conversion of urea to ammonia, which will easily lead to loss of urea and loss of volatiles. Therefore, urea and ammonium bicarbonate should not be mixed or applied simultaneously.
Misunderstanding 2: Surface spread. Urea is applied to the surface of the earth. At room temperature, it takes 3-5 days for conversion to be absorbed by crops. Most of the nitrogen is volatilized during the conversion of urea to ammonium. The utilization rate is only about 30%. Application, the loss of nitrogen is faster and more. Therefore, nitrogen cannot be spread on the surface.
Myth 3: Urea as a fertilizer. In the production process, urea often produces a small amount of biuret. Biuret content of more than 2% will poison seeds and seedlings. Urea enters seeds and seedlings and denatures proteins, affecting seed germination and seedling growth.
Misunderstanding 4: Apply water immediately after applying urea. Urea is an amide nitrogen fertilizer which must be converted into ammonium nitrogen before it can be used by crops. The process of conversion depends on the conditions of soil quality, moisture, temperature, etc. The time varies from time to time. It generally takes 2-10 days to complete. If urea is applied immediately after irrigation or dry land is applied before heavy rain, urea will dissolve in water and be lost. .
Misunderstanding 5: Mixed application of urea and alkaline fertilizers. After urea is applied, it must be converted into ammonium nitrogen to be absorbed and utilized by the crop. Ammonium nitrogen under alkaline conditions, most of the nitrogen will become volatile ammonia, therefore, urea can not be mixed with lime, grass ash, calcium magnesium phosphate fertilizer and other alkaline fertilizers or used simultaneously.
Misunderstanding 6: Urea is applied to celery. During the entire growth of celery, a large amount of nitrogen fertilizer should be applied, but no urea should be applied. Because of the topdressing of urea, the celery fiber becomes thicker, the plants are aging, and the growth is slow, and the consumption is bitter and the quality is poor. The celery is suitable for applying ammonium bicarbonate, ammonia, and organic fertilizers to improve quality.
