The sustainable use of agricultural lands is significantly affected by the implemented management and land processing methods. In sugar beet and wheat cropping, because the agronomic characteristics of plants are different, the tillage methods applied also exhibit significant variability. Soil quality concept is used, as a holistic approach to determining the effects of these applications on the sustainable use of soil. Agricultural soil quality evaluation is essential for economic success and environmental stability in rapidly developing regions. At present, a variety of methods are used to evaluate soil quality using different indicators. This study was conducted in one of the most important irrigated agriculture areas of Çumra plain in Central Anatolia, Turkey. In the soil under sugar beet and wheat cultivation, 12 soil quality indicators (aggregate stability (AS), available water capacity (AWC), surface penetration resistance (PR), subsurface penetration resistance (PR), organic matter (OM), active carbon (AC), potentially mineralizable nitrogen (PMN), root health value (RHV), pH, available phosphorus (AP), potassium (K), and macro-micro elements (ME) (Mg, Fe, Mn, and Zn)) were measured and scored according to the Cornell Soil Health Assessment (CSHA) and the Soil Management Assessment Framework (SMAF). The differences among 8 (AS, AWC, PR, PR, AC, PMN, AP, and ME) of these 12 soil quality characteristics measured in two different plant cultivation were found statistically significant. The result of the soil quality evaluation with scoring function in the examined area revealed a soil quality score of 61.46 in the wheat area and of 51.20 in the sugar beet area, which can be classified as medium and low, respectively. Low soil quality scores especially depend on physical and biological soil properties. Therefore, improvement of soil physical and biological properties with sustainable management is necessary to enhance the soil quality in the study area soils.
农业土地的可持续利用受到所实施的管理和土地处理方法的显著影响。在甜菜和小麦种植中，由于植物的农艺特性不同，所采用的耕作方法也存在显著差异。土壤质量概念被用作一种整体方法，以确定这些应用对土壤可持续利用的影响。农业土壤质量评估对于快速发展地区的经济成功和环境稳定至关重要。目前，人们使用多种方法，通过不同指标来评估土壤质量。本研究在土耳其中部安纳托利亚省居姆拉平原最重要的灌溉农业区之一进行。在甜菜和小麦种植的土壤中，根据康奈尔土壤健康评估（CSHA）和土壤管理评估框架（SMAF），测量并对12项土壤质量指标（团聚体稳定性（AS）、有效持水量（AWC）、地表穿透阻力（PR）、地下穿透阻力（PR）、有机质（OM）、活性碳（AC）、潜在矿化氮（PMN）、根系健康值（RHV）、pH值、有效磷（AP）、钾（K）以及大量和微量元素（ME）（镁、铁、锰和锌））进行评分。在两种不同植物种植中测量的这12项土壤质量特征中的8项（AS、AWC、PR、PR、AC、PMN、AP和ME）差异具有统计学意义。在研究区域，通过评分功能进行的土壤质量评估结果显示，小麦种植区的土壤质量得分为61.46，甜菜种植区为51.20，分别可归类为中等和低等。低土壤质量得分尤其取决于土壤的物理和生物学性质。因此，有必要通过可持续管理改善土壤的物理和生物学性质，以提高研究区域土壤的质量。
