Özet

125 SUMMARY In this study, the measurable structural properties of 6 soil series which are widespread in Harran Plain were studied before irrigation practices start. The structural properties were determined using 8 different methods on the soil samples taken from the genetical horizons of 23 different soil profiles. Then, the relationship between soil structural situation and some basic soil physical and chemical properties which could be effective on soil structure were determined. SPSSX computer program was implemented to determine the statistical relationship between some index values, and physical and chemical soil properties. The correlation coefficients indicated that increasing values of the organic matter, calcium carbonate, iron and aluminuim oxides C/N ratio, exchangable Ca+Mg, clay content, cation exchange capacity have positive effects on the aggragate stability. To find out the most effective ones among the above indicated properties a different approach was utilized. For this, first the structural properties and other soil properties possible effective on structure were shown in graphs. Later, regarding the soil series, soil properties effective on soil structure were studied with respect to; the surface horizons of each series, entire horizons af each series, surface horizons of all series and entire horizons of all series. For this, the values of correlation coefficient of the relationships between the structure and soil properties were arranged in the row starting from higher to lower, and then the soil properties of the first three highest coefficients for each structural property were established. The most repeating first three soil properties among the others were defined as the highly effective ones on the structural properties. After this evaluation it was found out that for the surface horizons, the organic matter content and C/N ratio were most effective on the aggragate stability, whereas clay contents, calcium carbonate126 and aluminium oxides for the sub surface horizons for the same respect. As an important soil physical property, high aggragate stability values obtained for 6 soil series which cover large portion of Harran Plain could be considered positively with regard to the irrigation practices and plant production. However, after the irrigation starts and in the fallowing period, it is most important to preserve this stability to hamper the problems associated with the determination in the soil structure. The infiltration rates of the series measured by ERŞAHİN (1990) and the aggregate stability values determined in this study were found to be in good correlation. While making the evaluation of the soil structure with respect to the plant productivity in the areas where intensive agriculture is practiced, the findings and information obtained from this study and the related literature directs one towards the fallowing conclusion; instead of seeking the relationship between the measured structural values and plant production, it would be more relavant to look for the relationship between physical and chemical properties which are affected by the structure, and plant productivity.
