Pistachio soft hull is substances that have a high potential for recycling and entry into production. Compost production is one of the ways to reuse and optimize them. In this study, the pistachio soft hull was collected and air dried, divided into two equal parts (T1 and T2 treatments) and stacked on either side of a chassis. A sample of primary wastes was sent to the laboratory and concentrations of macro- and micro-nutrients, organic matter, EC and pH were measured. Based on the results of previous studies and the deficiency of some elements in the prototype, some chemical compounds were added to one part of the waste (T2). The moisture content of the treatments was monitored regularly and the aeration was performed monthly. Samples were transferred to the laboratory monthly from two treatments for chemical tests and analyzed. Treatments were harvested and dried after the carbon to nitrogen ratio reached the permissible levels. The results of monthly tests were analyzed by a completely randomized design with the Duncan test at 5% level. The results showed that although the concentration of nutrients increased during the composting process, the increase in chemical fertilizers accelerated the decay process and also increased the concentration of nutrients. Elements added from the source of chemical fertilizers to the T2 treatment were significantly higher than the T1 treatment. EC, pH, phenol, and carbon to nitrogen ratios decreased.
