Assessment of relations between micro element availability and soil properties in Isparta-Atabey plain using principal component analysis
Abstract :
Soil properties influenced by soil formation processes and land use affect micro nutrition availability insoils. This study aims to reveal relationships between 24 measured soil parameters and micro elementavailability through descriptive statistics, Pearson correlation and principal analysis techniques, in 70surface samples (0-20 cm) taken from the 21 soil series of Isparta-Atabey plain. Positive and highskewness coefficients indicated that organic matter and available concentrations of phosphorus (P),copper (Cu), iron (Fe), and zinc (Zn) increased due to mainly agricultural practices and/or to relativelylesser extent soil forming processes. Principal component (PC) analysis indicated that sevencomponents explained about 80% of total variance and two of these components were responsible forthe variation in microelement concentrations. The principal component related to Cu and Zn in soilsshowed positive loading with available P, Cu, Zn, ammonium acetate extractable Mg; and negativeloading with only clay content of soils. The PC 5 explained the variation in Fe and Mn concentrations inrelation to negative loading of soil pH. Consequently, it was determined that the DTPA extractableconcentrations of Cu and Zn in some sampling sites have reached environmentally risky levels.
