Özet
Gediz Havzası yaygın tütün tarımı yapılan toprakların verimlilik durumlarının incelenmesine yönelik yapılan bu çalışmada, 60 farklı noktadan 0-30 cm derinlikten alınan toprak örneklerinin bazı fiziksel-kimyasal özellikleri ile besin elementi içerikleri belirlenmiştir. Araştırma sonuçlarına göre topraklar; genel olarak kumlu-tın bünyeli, hafif alkalin reaksiyonlu, kireçli, organik maddece iyi ve tuzluluk yönünden herhangi bir tehlike içermemektedir. Yöre toprakları genel olarak değerlendirildiğinde, %94’ünde toplam azot %62’sinde alınabilir K yetersiz iken, %70’inde alınabilir P, %85’inde alınabilir Ca ve %56’sında alınabilir Mg yeterli bulunmuştur. Toprakların genel olarak alınabilir Fe (%83’ü) ve alınabilir Cu (%92’si) kapsamları yeterli iken alınabilir Zn (%86’sı) ve alınabilir Mn (%85’i) içerikleri yetersizdir. İncelenen toprakların fiziksel-kimyasal özellikleri ve besin elementleri arasındaki ikili ilişkilerde, pH-Elektriksel İletkenlik (EC), pH-kireç, pH-silt, pH-kil, pH-K, pH-Ca; EC-N, EC-P, EC-K, EC-Ca, EC-Cu, EC-Zn; organik madde (OM)- N, OM-P, OM-Ca, OM-Cu, OM-Zn; % kum-Fe; kil-K, Kil-Ca, Kil-Mg, Kil-Cu içerikleri arasında pozitif; pH-kum, pH-Fe, pH-Zn ve pH-Mn; OM-kum; % kum-kil, kum-silt, kum-K, kum-Ca, kumCu; kil-Fe içerikleri arasında önemli negatif korelasyonlar bulunmuştur. Besin elementleri açısından toprakların N-P, N-Ca, N-Cu, N-Zn; P-Cu, K-Mg, Mg-Fe, Mg-Cu, Fe-Cu, Fe-Zn, Fe-Mn, Cu-Zn, Cu-Mn, Zn-Cu, Zn-Mn arasında pozitif; Ca-Fe arasında ise güçlü negatif ilişkiler belirlenmiştir. Tütünde kalite özelliklerini doğrudan etkileyen azot, Zn ve Mn elementlerinin yöre topraklarında yetersiz olması nedeniyle yörede yapılacak gübreleme programlarında bu durumun göz önünde bulundurulmasında yarar vardır.
This study was conducted to examine the soil fertility of the Gediz Basin, where tobacco is widely grown. Soil samples were taken from 60 points at a depth of 0-30cm, and various physico-chemical characteristics and nutritional elements were determined. According to the results of the study, the soils were generally sandy-loamy in texture, slightly alkaline in reaction, calcareous, good in terms of organic matter and in no danger from salinity. the soils of the area are generally found to be inadequate in total nitrogen (94%) and available potassium (62%), and adequate in available P (70%), available Ca (85%), and available Mg (56%). the available Fe (83%) and available Cu (92%) content of the soils was adequate, but available Zn (86%) and available Mn (85%) content was generally inadequate. in a statistical evaluation, positive correlations were found between soil pHElectrical Conductivity (EC), pH-lime, pH-silt, pH-clay, pH-K, pH-Ca, EC-N, EC-P, EC-K, EC-Ca, EC-Cu, EC-Zn, organic matter (OM)-N, OM-P, OM-Ca, OM-Cu, OM-Zn, % sand-Fe, clay-K, clayCa, clay-Mg and Kil-Cu contents, and significant negative correlations between pH-sand, pH-Fe, pH-Zn and pH-Mn, and OM-sand, % sand-clay, sand-silt, sand-K, sand-Ca, sand-Cu and clay-Fe content. With regard to nutrient elements, positive correlations were found between N-P, N-Ca, NCu, N-Zn, P-Cu, K-Mg, Mg-Fe, Mg-Cu, Fe-Cu, Fe-Zn, Fe-Mn, Cu-Zn, Cu-Mn, Zn-Cu and Zn-Mn, and strong negative correlations between Ca-Fe. Due to the insufficiency of nitrogen, zinc and manganese elements which directly affect the quality characteristics of tobacco, it is useful to consider them in the fertilization programs in the region.
