A new approach to the determination of phosphate rock dissolution in organic soils using graphite furnace atomic absorption spectrophotometry
The determination of phosphorus (P) in 0.5M NaOH extracting solution following the dissolution of phosphate rock (PR) materials in mineral soils is frequently done using a molybdenum blue method. For organic soils, 0.5M NaOH soil extracts usually give dark color solutions. This dark color solution r...
