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

The purpose of this investigation,was to comparison of different plant digestion methods (Di-acid & 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.
