Open full text 1,249 citations

Abstract

This new publication, which now replaces NZ Soil Bureau Scientific Report 10A, includes minor changes to existing methods and the addition of the following methods: Pyrophosphate-extractable carbon; 2 M KCl-extractable nitrate;\nOlsen-soluble phosphorus; Bray 2-soluble phosphorus; Total phosphorus (NaOH fusion); Leaching by automatic extractor (for cation exchange properties); Cation exchange properties determined by silver thiourea extraction; Phosphate-extractable sulphate determined by AutoAnalyzer. In addition, a new system of numbering the methods has been used.
