چکیده مقاله:

The present study is aimed to examine the effect of consuming compost ontransportation of copper and zinc in soil. There were four compost treatments and heavymetals (zinc and copper) and two control treatments (one compost soil and othercompost-free soil) as a completely random design. The runoff every time was taken anddetermined the concentrations of copper and zinc, EC and pH. The results show that theconcentration of zinc and copper during 12 times of leaching showed significantdifference at %1. The treatment No.4 has the maximum Zn concentration in outputrunoff (3.3 mg/lit) having the highest added zinc in compare with the other treatments.The control treatment No.2 had the maximum copper concentration (0.1 mg/lit). Thetreatment No.1 had the minimum copper concentration, and despite the added copper(290 mg/lit) to the mixture of soil and compost, little copper transported in soil. Also pHand EC have significant difference (%1) during 12 times of leaching.
