Analysis of Liquid Fertilizer by ICPE™-9820

Introduction

Fertilizers contain many elements which are useful in crop growth in addition to nitrogen, potassium, and phosphorus, which are the principal ingredients. As an analysis method for fertilizers, Japan’s Ministry of Agriculture, Forestry and Fisheries (MAFF) established Official Methods of Analysis of Fertilizers in 1992. However, because much time had passed since that standard was established, Food and Agricultural Materials Inspection Center (FAMIC) issued Testing Methods for Fertilizers, which introduced new analysis conditions and analysis methods suited to the times. Testing Methods for Fertilizers includes inductively coupled plasma (ICP) atomic emission spectrometry as an analysis method for watersoluble metallic ingredients. This article introduces an example of analysis of the watersoluble ingredients in liquid fertilizers using a Shimadzu ICPE9820 simultaneous ICP atomic emission spectrometer.
