A large amounts of proplant wastes is burned annually by ministry of defense. By this action air pollution and loss of asset will be caused. Annihilation of proplant waste with humic acid is one of the effective ways of reducing of pollution. With fortification of annihilated proplant wsates with macro and micro nutrients we could achieve to a beneficial organic fertilizer. For this purpose a greenhouse experiment in a completely randomized block design accomplished for nine weeks upon corn . Treatments consisted of two kinds of fortificated proplant waste by macro and micronutrients ( H1 – Annihilated with Iranian humic acid. H2- Annihilated with external humic acid) in four levels (Con.=0 , I1=250 , I2= 500 and I3=1000 mg/lit) in three replication . The results showed that corn had good responses to the higher concentration of Iranian fertilizer ( 1000 mg/lit ) but in external fertilizer low concentration (250 mg/lit) was more effective than higher rates. Finally , with consumption of both fertilizer the status of Zn, k , N and Ca in plant improved but Iranian fertilizer was more efficient with respect to external fertilizer.
