In this study, determination and distribution of some physical and chemical properties of agricultural soils wheat plant were grown in Çarşamba Plain were investigated. For this purpose, soil samples were taken from agricultural land cultivated by farmers in twenty villages of Çarşamba Plain in Samsun. The study was carried out between 2013-2014 in the same land. In accordance with this purpose, some physical (texture, field capacity, wilting point, bulk density) and chemical properties of soils (organic matter, soil reaction, electrical conductivity, lime content, total nitrogen, exchangeable cations, available phosphorus, cation exchange capacity, available Fe, Cu, Zn and Mn) were determined. According to results of research, the majority of the soils wheat crops were grown were found to have clayey loam textured, medium bulk density values (65%) and field capacity values of 85% were found as 20% - 40%. The great majority of the soils (72.5%) had slightly alkaline reaction and different amounts of lime contents and amounts of organic matter in the soils were determined to be moderate and soils were without salt. The amounts of nitrogen in the soils were low (57.5%) and potassium were medium (57.5%). 30% of phosphorus was defined as low, 35% as medium and 35% as high. 17.5% of cation exchange capacity was defined as medium, 47.5% as high and 35% as very high (35%). Amount of iron in the soils were (62.5%) medium, amount of copper (100%) was very high, half of manganese content was very low (50%) and the other half was low (50%) and amount of zinc was very low (80% ).
