Abstract With the increase of agricultural production, residues of crop are the main source of organic matter in the soil and they are alternatives to inorganic fertilizers. For this purpose, effects of organic residues (cotton stalk, maize stalk, almond bark) commonly grown in Turkey were investigated for some soil microbial activity in clay soil. In this study, incubation experiment was set up. Five doses (0%, 2%, 4%, 6% and 8%) of organic residues (maize stalks, cotton stalks or almond bark) were applied to soil. Soil microbiological properties of soil samples such as CO2 respiration, dehydrogenase and urease activity were determined. According to the results obtained, maize stalk, cotton stalks and almond bark applications increased some soil microbiological activities, such as CO2 respiration, dehydrogenase and urease activities according to control soil. Maize stalk in comparison to other residues affects better on the biological properties of the soil. It is determined that enhancing effects of the added organic residues (maize stalk, cotton stalk, almond bark) into the soil were changed according to the type of organic residues, dosage and application terms.

棉秆、玉米秆和杏仁皮对部分土壤微生物活性的影响

摘要 随着农业产量的增加，农作物秸秆是土壤有机质的主要来源，是无机肥料的替代品。为此，研究了土耳其常见的有机残留物（棉秆、玉米秆、杏仁皮）对粘土中某些土壤微生物活动的影响。本研究设置孵化实验。将五种剂量（0%、2%、4%、6% 和 8%）的有机残留物（玉米杆、棉杆或杏仁皮）施用于土壤。测定了土壤样品的土壤微生物特性，如 CO2 呼吸、脱氢酶和脲酶活性。根据获得的结果，玉米秸秆、棉花秸秆和杏仁树皮的施用增加了一些土壤微生物活动，如 CO2 呼吸、脱氢酶和脲酶活性根据对照土壤。与其他残留物相比，玉米秸秆对土壤的生物学特性影响更大。确定添加到土壤中的有机残留物（玉米秆、棉花秆、杏仁皮）的增强效果根据有机残留物的类型、用量和施用期限而变化。
