Are all the foliar fertilizers sprayed the same number of times?
Ms. Song of Wafangdian in Liaoning Province asked: Regardless of the foliar fertilizer, the spraying frequency is the same?
Answer: The frequency and time interval of two sprays are related to the speed with which fertilizers are absorbed and utilized. Foliar fertilizer is the fastest in urea, followed by phosphorus and potassium, and trace element fertilizer is the slowest. The slower the fertilizer is absorbed, the more times the spray is sprayed, and the more carefully it is sprayed. The leaf back does absorb more nutrients than the leaf surface. In general, as long as it is sprayed 2 or 3 times, the leaves and leaves are sprayed. The excess solution begins to drip onto the ground.
