Abstract (2. Language): 
In this study, the pedotransfer functions for the vertical saturated hydraulic conductivity, water contents at the suctions of 0- (saturation), 60- (drainable porosity), 100-, 330- (field capacity), 1000-, and 15000-cm (permanent wilting point) were developed using easily measurable soil physical and chemical properties obtained from 34 horizons of nine profiles from a lake origin of Northwest Ohio plain. For this analysis, the multiple-linear regression analysis by stepwise method was employed. The accuracy of these functions were evaluated using the measured vertical saturated hydraulic conductivity and water contents at the field capacity and wilting points from the soils of 19 horizons of five profiles of an alluvial Yeşilırmak River valley close to the downtown of Tokat city. The results of evaluation showed that the developed pedotransfer functions for the vertical saturated hydraulic conductivity and field capacity produced under and over predictions, respectively. The developed pedotransfer functions for the wilting point yielded fair results.

Abstract (Original Language): 
Bu çalışmada, göl orijinli Kuzeybatı Ohio'daki bir ovanın dokuz profiline ait 34 horizonundan alınan toprak örneklerinde ölçülmüş basit toprak fiziksel ve kimyasal özellikleri kullanılarak, düşey doygun hidrolik iletkenlik, 0- (doygun), 60- (drene edilebilir porozite), 100-, 330- (tarla kapasitesi), 1000-, ve 15000-cm (devamlı solma noktası) emme basınçlarındaki su içerikleri için pedotransfer eşitlikleri geliştirilmiştir. Bu işlemde, stepwise yöntemli çoklu doğrusal regresyon analiz yöntemi kullanılmıştır. Geliştirilen eşitliklerin doğrulukları, Tokat merkeze yakın alüvyal Yeşilırmak vadisinde açılan beş profilin 19 horizonuna ait toprak örneklerinde ölçülmüş, düşey doygun hidrolik iletkenlik, 330- ve 15000-cm emme basınçlarına karşılık toprakta tutulan su içerikleri kullanılarak değerlendirilmiştir. Hidrolik iletkenlik ve tarla kapasitesi (330-cm) için geliştirilmiş eşitlikler sırasıyla düşük ve yüksek sonuçlar üretmiştir. Devamlı solma noktası (15000-cm) için geliştirilmiş eşitlikler ise orta derecede iyi sonuçlar üretmiştir.
