Özet:

 Land uses and associated management practices can significantly change soil properties in agricultural areas. These changes in soil properties can cause both a decrease in soil fertility in agricultural areas and an increase in the sensitivity of agricultural soils to various processes such as climate change, erosion, and desertification. The current study investigated the effects of long-term land use types on soil properties in alluvial soils located in the Çarşamba plain. Soil properties such as aggregate size distribution, soil organic carbon SOC content associated with aggregates and soil organic carbon stock SOCStock, structure stability index SSI, aggregate stability index ASI, unstable aggregate index ELT, mean weighted diameter MWD and geometric mean diameter GMD were measured in soil samples collected from five different land use types vegetable, cherry, persimmon, maize, and rice and three different soil depths 0.0-7.5 cm, 7.5-15.0 cm, and 15.0-30.0 cm. The results showed that different land use types statistically affected all the examined soil properties p0.05, p0.01. The highest and lowest SSI values were obtained in persimmon land use 2.2 and rice land use 1.8, respectively, while the same land uses were found to have the statistically highest values 0.8 for ASI. Vegetable land use had the highest statistical impact on aggregate-associated SOC content across most of the examined aggregate sizes. Therefore, it is recommended to perform rotation cropping systems that increase organic matter OM input to reduce the adverse effects of land uses and soil management on aggregates-related SOC content and SOCStock in alluvial areas.

 Arazi kullanımı ve onunla ilişkili yönetim uygulamaları tarımsal alanlardaki toprak özelliklerini önemli ölçüde değiştirebilmektedir. Toprak özelliklerinde meydana gelen bu değişimler hem tarımsal alanlarda toprak verimliliğinin azalmasına hem de tarımsal toprakların iklim değişikliği, erozyon, çölleşme gibi çeşitli süreçlere hassasiyetinin artmasına neden olabilmektedir. Mevcut çalışmada, Çarşamba ovasında yer alan alüviyal topraklarda, uzun süreli arazi kullanım tiplerinin toprak özellikleri üzerindeki etkileri incelenmiştir. Beş farklı arazi kullanım tipinden sebze, kiraz, Trabzon hurması, mısır ve çeltik ve üç farklı toprak derinliğinden 0.0-7.5 cm, 7.5-15.0 cm, ve 15.0-30.0 cm alınan toprak örneklerinde agregat büyüklük dağılımı, agregatlar ile ilişkili toprak organik karbon TOK içeriği ve toprak organik karbon stoğu TOKStoğu, strüktür stabilite indeksi SSI, agregat stabilite indeksi ASI, kararsız agregat indeksi AIKararsız ,ortalama ağırlıklı çap OAÇ ve geometrik ortalama çap GOÇ gibi toprak özellikleri ölçülmüştür. Elde edilen sonuçlar, farklı arazi kullanım tiplerinin incelenen bütün toprak özelliklerini istatistiksel olarak p0.05, p0.01 etkilediğini göstermiştir. En yüksek ve en düşük SSI değerleri sırasıyla Trabzon hurması arazi kullanımı  2.2 ve çeltik arazi kullanımında 1.8 elde edilirken, aynı arazi kullanımlarının ASI için istatistiksel olarak en yüksek değerlere 0.8 sahip olduğu bulunmuştur. Sebze arazi kullanımı, incelenen agregat büyüklük fraksiyonlarının büyük çoğunluğunda agregatlar ile ilişkili TOK içeriği üzerine en yüksek istatistiksel etkiyi ortaya koymuştur. Bu nedenle, alüviyal alanlarda arazi kullanımları ve toprak yönetimlerinin agregatlar ile ilişkili TOK içeriği ve TOKStoğu üzerindeki olumsuz etkilerini azaltmak için organik madde OM girişini artıran rotasyon ekim sistemlerinin uygulanması önerilmektedir.
