Analisa Unsur Hara Kalium (K) dalam Tanah secara Spektrofotometri Serapan Atom (SSA) di Pusat Penelitian Kelapa Sawit (PPKS) Medan

Abstract

Analysis for the values of potassium element (K) in soil had done for plant of palm in Palm Research Center (PPKS) Medan. The values of potassium element (K) which measured with extract ammmonium acetat (CH3COONH4) by using Atomic Absorption Spectrophotometer (AAS). From the resulting of measuring, got the values of potassium element (K) which low (deficiency) at the sample of soil. The values of potassium element (K) which got, content in soil was about 0,09 – 0,12 me/100 g K.
