DETERMINATION AND CLASSIFICATION OF DIFFERENT SOILS FORMED ON FLUVIYAL LAND

Alluvial land, formed on accumulated sediment depositions by time, show large variety in their properties at short distances. Therefore, different soils can be form on these lands. The objective of this research was to determine and classify different soils formed on alluvial land used for rice cultivation in Corum-Osmancik. Total study area is approximately 1663 ha. Average annual temperature and precipitation are 13.2 oC and 380 mm, respectively. After examination of topographic, land use, geologic and geomorphologic maps and land observation, 12 profile places were excavated in study area. Detailed land observations were done with grid method and auger examinations. The soil samples were taken from each profile and their analyses were done in the laboratory. By assessing the results of analyses and field studies, 9 different soil series were determined and described. Two of them were classified as Entisol due to their young age and four are as Inceptisol and three are as Mollisol. Whereas Taslikbasi series has the largest area (18.9 %), Dagmatoglu series has the smallest area in the study area (4.0 %). Also, suitability of soil series was investigated for the rice production and soil properties limited rice production were determined in this study.
