This research was carried out in order to determine the productivity status of agricultural lands where soybean plants were grown by traditional soil cultivation methods in Çarşamba Plain. For this purpose, soil samples were taken from the lands where soybean cultivation was carried out in 20 villages on the plain and their some physical and chemical properties were determined. In addition, some agronomic components were determined by taking plant samples from the same land. The research was executed on the same lands for two years. According to the research results, the soils usually were determined to have clay and clay loam, bulk density values 1.0-1.3 g cm-3 (62.5%), field capacity values of 55% were found as 30-40%, neutral and slightly alkaline reaction, salt-free, limeless and medium-lime, organic matter was determined at a moderate and good level (62.5%). The nitrogen content of the soils was medium and high (44.5%), the amount of phosphorus was low and medium (57.5%), the amount of potassium was medium (67.5%), and the cation exchange capacity was very high (65%). Content of iron in the soils was high (65%), content of manganese was low (85%), content of copper was very high (92.5%), and content of zinc was very low (90%). The average plant height, thousand seed weight and seed yield values of soybean were determined as 103.31 cm, 200.54 g and 455.87 kg da-1, respectively. Since the organic matter, nitrogen and phosphorus contents of the research soils are generally low, the yield will be increased by applying organic, nitrogenous and phosphorous fertilizers to the soils.
