Urea is favored by vegetable farmers, but care should be taken when applying urea. Do not water it immediately after use. Because the nitrogen component contained in urea is ammonium, and the amido ammonium nitrogen is converted into ammonium carbonate or ammonium bicarbonate under the action of urease secreted by soil microorganisms, it is used for vegetable root absorption and utilization. If the urea is applied immediately after watering or rain, ammonium nitrate will be lost. Therefore, whether urea or vegetable fertilizer base fertilizer, should be applied after 5 to 6 days, so that all the conversion after the water, so as to avoid loss.
