ABSTRACTMASTER THESISEmel DEM RÖZSelçuk UniversityGraduate School of Natural and Applied SciencesDepartment of Soil ScienceTHE EFFECTS OF HEATING IN SOME PHYSICAL AND CHEMICALPROPERTIES OF THREE SOILS WITH CONTRASTING TEXTURESupervisor: Prof. Dr. Cevdet EKER2006, Pages: 59Jüri: Prof. Dr. Saim KARAKAPLANProf. Dr. Cevdet EKERYrd. Doç. Dr. H.Hüseyin ÖZAYTEK NThis investigation was made to determine the effect of heating on select physical andchemical properties of three different soils in laboratory condition. Heating was conductedtwo different temperatures (205 0C and 500 0C) and two different water contents (air dry and50% of field capacity) for 30 minutes.Obtained results showed that a decreasing in the values of pH, organic matter content,surface area and available Zn, and an increasing in the values of EC (electrical conductivity),aggregate stability, extractable Ca, Mg, Na and K, available P, Fe, Cu, and Mn, and nochancing of the soil textural classes of the soil samples heated in 250 0C compare with controlsamples. Lime contents of the clay and sandy clay loam textured soils not chanced at 250 0Ctreatments, lime content of clay loam textured soil was increased.Other wise, the treatments of 500 0C heating increased pH, EC and aggregate stabilityvalues, extractable Ca, Mg, Na and K, available P, Fe, Cu, and Mn contents, and decreasedorganic matter content, surface area and available Zn contents of the soils compare withcontrol samples. All three soils textures were chanced with 500 0C treatments. While claycontents of the soil samples were decreased, sand contents were increased relatively withtemperature. Lime contents of the clay and sandy clay loam textured soils were decreasedwith 500 0C treatments similar to 250 0C treatments, lime content of clay loam textured soilwas increased.Effect of different water contents on select physical and chemical properties of soils wassignificant by statistical. Fifty percent of field capacity water content, the treatmentsdecreased in chancing of the soils physical and chemical properties compare with air drytreatments. Soil water content was decreased adverse effect of the heating.ii
