Abstract :

Introduction: Application of sulfur and organic matters has an important role in improving ofphysicochemical properties in soils. In this research optimizing the mixture design between sulfur andmunicipal solid waste compost for application in an alkaline soil was tested.Materials & Methodology: In this research randomized designs with three replications is used. Theapplied factors were the total fertilizer content of compost and sulfur, M, and the ratio between sulfurand compost in fertilizer, T. M factor had four options, zero,0.5, 1 and 2 percent of soil weight and Tfactor include 1:1, 1:2, 1:3 and 1:4 sulfur to compost ratios.Discussion & Results: The obtained results indicated that all of treatments with 99 percentcontingency decreased the soil pH and T2M4 treatment had the best influence. The content of Znuptake by corn has been significant in 5 percent level in many treatments. The content of Fe uptakehad remarkable incensement in treatments, but it wasn't significant.
