The study of concentrations and forms of zinc in composting of pig-manure containingzinc were conducted by using appropriate mixture of pig-manure and sawdust with total zincconcentrations of 566, 806, 1595 and 2707 mg zinc per kg dry weight of raw compostingmaterial. Concentrations and forms of zinc investigated during composting process are theobjectives of this research. In addition, forms of zinc uptake by Chinese Kale in the mixture ofproduced compost product and agricultural soil well as accumulations of zinc in different partsof Chinese Kale were also observed. Based on the first phase experimental results, it was found that total zinc concentrationsin term of "mg zinc per kg dry weight of compost" gradually increased as composting timeincreased. However, constant total zinc concentration in the compost after 9 weeks compostingperiod were notified. Total zinc concentrations in compost products of 1062, 1410, 2867 and4886 mg zinc per kg dry weight of compost, which were about 80 percent higher than those of inraw composting materials, were obtained after complete stabilization of 17 weeks compostingperiod. Zinc containing in compost products in water soluble form, exchangeable form,organically bound form, carbonate precipitated form, solid particulate form and residual were 1.2,0.1, 3, 32, 53 and 10.7 percent, respectively. In the second phase study, The ratio of 2 : 1 of agricultural soil mixed with the obtainedcompost product form the first phase experiment were used for cultivation of Chinese Kale. Theresults showed that only zinc in water soluble form, exchangeable form and organically boundform in mixed soil, which could be utilized by Chinese Kale, were decreased as cultivating timeincreased, but zinc in carbonate precipitated form and solid particulate form were not significantlychanged. Additionally, accumulations of total zinc concentrations in root, trunk and leave of 92,48 and 121 mg of zinc per kg dry weight of Chinese Kale, respectively, were found after theharvest of 8 weeks cultivating period.
