Influence of Nano-Zinc Oxide Coated Urea Fertilizer on Ammonia Volatilization Loss and Inorganic Nitrogen Content in Loamy Sand Soil

A laboratory incubation experiment in a closed dynamic air flow system was conducted for 30 days to estimate the volatilization loss of NH3-N from 0, 1, 2 and 3% Nano-ZnO coated urea treated soil. The volatilized soil chambers collected titrated every 48 hours. Another carried out study effect coating with on inorganic nitrogen (NH4-N NO3-N) content soils at 2, 4, 8, 14 21 period. two experiments were arranged completely randomized design three replications. results first indicated that fertilizer Nano-ZnO  reduced total 22.82 % applied N uncoated (0 coating) 13.03% highest level (3%) reduction by 42.90%.The second showed average NH4-N increased 86.52 mg Kg-1 0% Nano-Zn 131.04 urea, ratio extractable NO3-N 1: 1.06, 1.17, 1.50 1.75 respectively. Also, 168.19 (0% 205.70 with  (3%).Therefore, using improves use efficiency and  reduce ammonia loamy sand
