<p>This study investigates the relationship between soil properties and nematode diversity in three vineyards in Tekirdağ province, Türkiye. Soil samples were analyzed for pH, salinity, lime content, texture, and nutrient composition. The soils were slightly alkaline (pH 7.38–7.71) with low salinity (0.02–0.03 dS/m). Vineyard&#xa0;2 had the highest lime content (13.62%) and the lowest organic matter (0.74%), while Vineyard&#xa0;3 had the highest organic matter (1.77%). Potassium levels were uniformly high across vineyards (5867.69–6366.85 mg/kg), and Vineyard&#xa0;1 had the highest calcium, magnesium, phosphorus, and nitrogen concentrations. A&#xa0;total of 30 nematode genera from seven orders were found, with 23 at species level identified. Vineyard&#xa0;1 exhibited the highest diversity and species richness (Shannon Index: 3.69, Margaleff Index: 4.99) and had the greatest enrichment, structure, and predator footprints. Vineyard&#xa0;2 showed lower diversity and dominance of bacterivore and herbivore footprints, whereas Vineyard&#xa0;3 had moderate diversity and the highest ectoparasite percentage (70%). Principal component analysis revealed that potassium, calcium, phosphorus, organic matter, and lime significantly influenced nematode distribution. Genera such as <i>Mesocriconema</i> and <i>Boleodorus</i> thrived in nutrient-rich soils, while <i>Rhabditis</i> and <i>Tylenchorhynchus</i> were associated with organic matter.

摘要

This study investigates the relationship between soil properties and nematode diversity in three vineyards in Tekirdağ province, Türkiye. Soil samples were analyzed for pH, salinity, lime content, texture, and nutrient composition. The soils were slightly alkaline (pH 7.38–7.71) with low salinity (0.02–0.03 dS/m). Vineyard 2 had the highest lime content (13.62%) and the lowest organic matter (0.74%), while Vineyard 3 had the highest organic matter (1.77%). Potassium levels were uniformly high across vineyards (5867.69–6366.85 mg/kg), and Vineyard 1 had the highest calcium, magnesium, phosphorus, and nitrogen concentrations. A total of 30 nematode genera from seven orders were found, with 23 at species level identified. Vineyard 1 exhibited the highest diversity and species richness (Shannon Index: 3.69, Margaleff Index: 4.99) and had the greatest enrichment, structure, and predator footprints. Vineyard 2 showed lower diversity and dominance of bacterivore and herbivore footprints, whereas Vineyard 3 had moderate diversity and the highest ectoparasite percentage (70%). Principal component analysis revealed that potassium, calcium, phosphorus, organic matter, and lime significantly influenced nematode distribution. Genera such as Mesocriconema and Boleodorus thrived in nutrient-rich soils, while Rhabditis and Tylenchorhynchus were associated with organic matter. These results highlight the critical role of soil properties in shaping nematode communities and inform sustainable vineyard management.
