Comparison of Different Plant Digestion Methods ( Di-acid & Microwave) for Phosphorus Determination Content of Potato Leaf Using Spectrometry Grown in Erzurum: Pasinler and Oltu District Agricultural Soils

Abstract

Abstract-The purpose of this investigation,was to comparison of different plant digestion methods ( Diacid & Microwave) for used to determine phosphorus (P) content of potato leaf grown in of Pasinler and Oltu District Agricultural Soils . Representative 74 leaf samples were collected from potato grown in different soil locations. In order to comparison were used two different digestion methods. Using the microwave and di acid (HNO 3 +HCLO 4 ) digestion technique, P contents in potato leaf were determined, and , spectrometry was used for the determination of P in leaf samples in Erzurum, Oltu,Pasinler, Turkey. The results of the statistical analyses indicated that , did not show any significant differences between the two digestion systems of P nutrient . This result indicates that these systems can be used for the digestion of plant P content in Erzurum, Pasinler and Oltu district agricultural soils either by using concentrated di acid (nitric-perchloric acid) or microwave digestion methods.
