One-month-old wheat (Triticum aestivum L. sp.) seedlings were exposed to 13.6 m/sec wind velocity and sand at 1 kg/min for different lengths of time in a wind tunnel. Urea solution was foliar applied at different time intervals of up to 4 days after exposure. Total nitrogen content of the tissues decreased as follows: wind plus sand greater than wind alone equal unexposed. There was a strong indication that foliar uptake of urea was greater when the urea solution was applied soon after exposure to wind and sandPlease view the pdf by using the Full Text (PDF) link under 'View' to the left.
