Determination of some physical properties of Suruç plain soils of Şanlıurfa province

Abstract

Objective: Soil physical properties are an important soil quality parameter that determines the sensitivity of soils to erosion. This study was carried out in Suruç Plain in Suruç district of Şanlıurfa province.

Materials and Methods: The physical properties of the soils (volume weight, aggregate stability, soil water content, body) were determined as a result of the sampling study carried out at 70 different points in Suruç Plain from 0-30 cm depth at the coordinates taken by GPS.

Results: Volume weight of soils varied between 1.32-1.38, aggregate stability between 30.02-53.28, field capacity between 14.08-27.36, and wilting point varied between 7.29-18.35. The results are respectively r=0.29 as the pearson correlation coefficient between aggregate stability and volume weight and r=0.38 as the correlation coefficient between field capacity and volume weight of soils, between these two parameters, at p<0.01 level a very important relationship, r=0.27 as the correlation coefficient between the wilting point and volume weight, and the relationship between them according to the significance level p>0.05, an important relationship, the correlation coefficient between the clay content and the field capacity r=0.36 and according to the significance level p<0.01 very important, correlation coefficient r=0.47 between clay contents and volume weight and p<0.01 very important relationships were determined according to significance level.

Conclusion: Determination of soil physical properties requires more work to be done in the study area and in addition to the physical properties of the soil, chemical and biological analysis should be done.

Şanlıurfa ili Suruç Ovası topraklarının bazı fiziksel özelliklerinin belirlenmesi

Öz

Amaç: Toprak fiziksel özellikleri toprakların erozyona karşı duyarlılığını belirleyen önemli bir toprak kalite parametresidir. Bu çalışma Şanlıurfa İli Suruç İlçesinde yer alan Suruç Ovasında yürütülmüştür.

Materyal ve Yöntem: . Suruç Ovasında 70 farklı noktada GPS ile koordinatları alınan noktalarda 0-30 cm derinlikten yapılan örnekleme çalışması sonucunda toprakların fiziksel özellikleri (hacim ağırlığı, agregat stabilitesi, toprak su içeriği, bünye) belirlenmiştir.

Araştırma Bulguları: Toprakların hacim ağırlığı 1.32–1.38 arasında, agregat stabilitesi 30.02 – 53.28 arasında, tarla kapasitesi 14.08–27.36 arasında ve solma noktası ise 7.29–18.35 arasında değişmiştir. Sonuçlar sırasıyla agregat stabilitesi ile hacim ağırlığı arasında pearson korelasyon katsayısı olarak r=0.29 ve aralarında (p<0.05) önemli ilişki, tarla kapasitesi ile toprakların hacim ağırlığı arasında korelasyon katsayısı olarak r=0.38 olup, p<0.01 düzeyinde çok önemli bir ilişki, solma noktası ile hacim ağırlığı arasında korelasyon katsayısı olarak r=0.27 ve p<0.05 düzeyinde önemli bir ilişki, kil içeriği ile tarla kapasitesi arasında korelasyon katsayısı r=0.36 ve p<0.01 düzeyinde çok önemli, kil içerikleri ile hacim ağırlığı arasında korelasyon katsayısı r=0.47 ve p<0.01 düzeyinde çok önemli ilişkiler belirlenmiştir.

Sonuç: Toprak fiziksel özelliklerinin belirlenmesi çalışma yapılan alanda daha fazla çalışmanın yapılması gerektiğini ve toprakların fiziksel özelliklerine ilave olarak kimyasal ve biyolojik analizlerin yapılması gerekmektedir.
