Abstract :
It has recently been shown that rubber can be used as an effective source of zinc (Zn) and some other nutrients for crops. According to the previous results, rubber particles size is a key factor determining the rate of micronutrient release from the rubber wastes. In this study, different treatments were applied to synthesis Zn nano-particles from waste tire rubber. According to the results obtained, nano-zinc particles synthesized from waste tire rubber offer strong value as Zn fertilizer for cucumber grown in the nutrient solution culture. The cucumber seedlings grown in nutrient solution containing nano-Zn particles had higher shoot growth and accumulated higher amounts of Zn in their tissues compared with those grown in control and ZnSO4-containing nutrient solution.
