In the Bursa plain, Regosols are extensively cultivated soils for horticultural crops and irrigated by water from aquifers. These soils are quite widespread on the west side of the plain and developed on different types of parent materials. | Turk J Agric For 24 (2000) 511–517 © TÜBİTAK Characterization of Some Regosols in the Bursa Plain Cumhur AYDINALP Uludağ University, Faculty of Agirculture, Department of Soil Science, 16384 Bursa-TURKEY Received: Abstract: In the Bursa plain, Regosols are extensively cultivated soils for horticultural crops and irrigated by water from aquifers. These soils are quite widespread on the west side of the plain and developed on different types of parent materials. This research was carried out to determinate genesis and classification of the Regosols developed on calcareous colluvium material. Five soil profiles were examined in this research and their characterization included field morphology and physico-chemical analysis. The soils were classified according to the systems of FAO/Unesco (1990), FitzPatrick (1988), and USDA Soil Taxonomy (1994). The soils show high sand and calcium carbonate contents increasing with depth. Bursa Ovasındaki Bazı Regosolerin Karekterizasyonu Özet: Regosoller Bursa ovasında yaygın olarak bahçe bitkileri tarımında kullanılıp, artezyenlerle sulanmaktadır. Ovanın batı kesiminde oldukça yaygın olarak bulunan bu topraklar çeşitli ana materyaller üzerinde oluşmuşlardır. Bu araştırma kalkerli kolüviyal materyal üzerinde oluşmuş olan Regosollerin genesis ve sınıflandırılmasının belirlenmesi için yapılmıştır. Bu araştırma kapsamında beş toprak profili incelenmiş ve bunların morfolojik, fiziksel ve kimyasal analizleri yapılmıştır. Topraklar FAO/Unesco (1990), FitzPatrick (1988), ve USDA Toprak Taksonomisi (1994) sistemlerine göre sınıflandırılmıştır. Topraklarda derinlikle artan yüksek kum ve kireç içeriği görülür. Introduction In the Bursa plain, Regosols are extensively cultivated soils on the west side of the basin. The soils have been cultivated by horticultural crops. The investigated soils are colluvial according to the old system of soil classification (1). These correspond to the Regosols of FAO Legend as defined (2). The .
