Ahmetli (Manisa) sol sahil sulama alanı topraklarının 7.öneri sistemindeki taksonomisi ile arazi kullanım yetenek sınıfı üzerine araştırmalar

Abstract

79 SUMMARY This research has been purposed to classify the land belovging to Ahmetli irrigation area according to the 7th approximation system and to make detailed soil survey and to map by considering land classification determined before. The research area covers the land which lies between the road to Seyitoğlu village and Alahı di r river. Sediment originated soils of the research area has been formed over alluvium parent materials accumulated by Gediz River and its branches in the river basin which keeps the region under effect it is possible to watch geological formations pertaining to certain geological periods. Research material has consisted of 35 samples obtained from different horizons or layers of each soil pedon, totally 7, opened at the most representative places of the area in which general characteristics of the research area soils and distinctions in land observations were determined. As a detailed soil survey and soil mapping were proposed at the beginning of the research, for the purpose at classifying the soil families with the 7th approximation system describing pedons in the area, particle size distribution, pH, CaCO, 3 organic-C, organic matter, total N, C/N, exchangeable cations, C.E.C., E.S.P., free Fe 0, field capacity, wilting point, and + + +.+ `++ - a a E.C., Na, K, Ca, Mg, CI. SO,, CCL and HCO` contents in 4 3 3 water extract has been brought out.80 In the light of land observations and data from laboratory analysis, surface horizon (A) was shaped like ochric epipedon. This horizon is hard and non fragmented on summer days. Besides., the soils of which the diagnosis horizon were not able to be determined have been classified in two orders, Entisol and Inceptisol, in three suborders, Fluvent, Psamment and Ochrept, in three great groups, Xerofluvent, Xeropsamment, Xerochrept, in two subgroups, typic and fluventic, in four family; loamy, mixed (calcareous), thermic Typic Xerofluvent; loamy over sandy, mixed (calcareous), thermic Typic Xerofluvent; mixed, thermic Typic Xeropsamment; loamy, mixed, thermic Fluventic Xerochrept. A great majority of the land located in 1st class lands. The main reasons for the remaining area to be 2nd and 3rd classes, are increase in the texture of sand and sandy loam and increase in the amount of big gravels.
