Summary : The objectives of research about effect of soil tillage to soil characterization on soil physical properties, soil chemical properties and soil mineralogy properties. Determine of soil profiles is based on geology map, soil map and land tillage map with parent material volcanic ash and order of soil as Inceptisol sub group of Andic Dystrudept. Soil characterizations in southern slope of Merapi Mountain mostly have 3 system of soil tillage as none soil tillage, minimum soil tillage and conventional soil tillage. The result of research showing that more intensively made soil tillage will reduce soil fertility for plant. LAnd use basically to plant growth condition to oryza sativa and salaccae on soil tillage can impact to physically properties and chemically properties but none significantly to mineralogical properties. Result of XRD by each horizon none showing yet clay mineral crystalline as kaolinite or haloysite, still amorphous mineral form like allophane (Al2, O32SiO2 2H2O). Order of soil on research area based on different system of soil tillage is family Andic Dystrudept, Amorphic, Isohipertermic.
