This study was done with the aim of determining the effect of organic material application on some structural stability indicators with the limits of weakness in the soil. In this study carried out under natural conditions, in increased rates to increase the content of organic substances in the soil, waste compost made from urban solid waste was used. The study also used wood fertilizer in equivalent proportions to compare the level of effect of waste compost. According to the findings obtained from the research, the waste compost applied to the soil in increased rates has significantly increased the organic content of the soil. As a result of the increase in organic content, the liquid limit values have increased, the plastic limit values have increased in the soil limits. These increases in the limit values also raised the amount of moisture necessary for the soil to be processed. The positive effect of the application of waste compost has also been seen in the relationship between the soil’s Boekel ratio and aggregate stability. A RESEARCH ON THE EFFECT OF MUNICIPAL WASTE COMPOST APPLICATION ON THE CONSISTENCY LIMJCTS AND SOME STRUCTURAL STABILITYINDEXES OF SOILS SUMMARY In this study, the effect of organic material application on the consistency limits and some structural stability indexes was determined. This study vv&s conducted at the natural conditions and municipal waste compost obtained from town solid residues was used at increasing rates. In experiment, barnyard manure was applied corresponding to equivalent municipal compost treatment levels according to total organic matter content. As a result of the research it found that; municipal waste compost applied to soils at increasing rates, significantly increased the organk matter content of soils. Consistency limit values increased, this itcrease occured low in "lcrwerplastic limit" values and high in "upper plastic limit" values because of increasing of organic matter content. This increasin the c onsistency limit values, increased moisture content which is necessary for tillage. In addition, municipal waste compost application positively effected on the relationship between Boekel's ratio and water stable aggregates.
