Zinc humic acid urea has good hygroscopicity, and the dry land topdressing should be as much as possible after the rain, so that the fertilizer dissolves quickly and is adsorbed by the soil. Moreover, the temperature is low and it is difficult to volatilize ammonia. At the same time, some fertilizer can be absorbed through the leaves to improve fertilizer efficiency and reduce losses. Urea should not be applied at noon in direct sunlight, otherwise the amount of ammonia volatilization will increase, causing damage to the leaves and causing fat damage.
