Studying altitude influence on Uludağ fir soil macro nutrients in Kastamonu, Turkey

Abstract

Soil macronutrients (P, K, Ca +2 and Mg +2 ) showed significant differences between the altitudes (p<0.05).Mean soil macronutrients; Mg, P and K concentrations were significantly higher at the higher altitude than those at the lower altitude, whereas mean soil Ca +2 concentration was lower at the higher altitude than those at the lower altitude.Soil micronutrients, Mn +2 , Na, Zn +2 , Cl, Al and Co concentrations were also significantly higher at the higher altitude than those at the lower altitude.In conclusion, our results indicate that topographical factors, the slope aspect in this present study, can significantly affect soil properties and soil organic carbon and total nitrogen content.Therefore, those factors should be considered in future studies.
