Farklı Tekstürdeki Toprakların Potasyum Fiksasyon Kapasiteleri
Bu çalışmada, kil, tın ve tınlı kum tekstüre sahip toprakların potasyum fiksasyon kapasiteleri Langmuir ve Freundlich izotermleri ile belirlendi ve izoterm katsayıları ile toprak özellikleri arasındaki ilişkiler araştırıldı. İzotermlerin b ve Kf absorpsiyon değerlerine göre, toprakların potasyum adsorpsiyon kapasiteleri kil > tın > tınlı kum şeklinde sıralanmıştır. Kil bünyeli toprak tın ve tınlı kum topraklardan daha fazla toprak çözeltisine K iyonu sağlama kapasitesine sahipti. Potasyum adsorpsiyon kapasitesi katsayıları kil, organik madde, katyon değişim kapasitesi, değişebilir K, Ca ve Mg içerikleri ile önemli pozitif korelasyonlar, pH, CaCO3 ve kum içeriği ile önemli negatif korelasyonlar vermiştir. Toprakların potasyum fiksasyon mekanizmaları toprakların tekstür ve diğer fizikokimyasal özelliklerine bağlı olarak değişmiştir. Sürdürülebilir ve üretken toprak yönetiminde, toprakların K adsorpsiyon kapasitelerinin doğru gübreleme programı için belirlenmesi gerekir.
The Potassium Fixation Capacities of Different Textural Soils
In this study, potassium fixation capacities of clay, loam and loamy sand soils were determined byLangmuir and Freundlich isotherms, and relationships between isotherm coefficients and soil properties wereinvestigated. While the Langmuir isotherm gave the best fit for K adsorption of clay and loam soils, Freundlichisotherm gave the best fit for K adsorption of loamy sand soil. Potassium adsorption capacities of the soilsordered as clay > loam > loamy sand soil according to the b and Kf absorption values of the isotherms, Clay soilhad more ability to supply K ion to soil solution than loam and loamy sand soils. Potassium absorption capacitycoefficients gave significant positive correlations with clay, organic matter, cation exchange capacity,exchangeable K, Ca and Mg contents and significant negative correlations with pH, CaCO3 and sand content.The potassium fixation mechanisms of soils varied depend on soil textural and other physicochemical properties.In sustainable and productive soil management, K absorption capacities of soils should be determined for correctK fertilization programme.
