WebAt acidic pH values, phosphate ions react with aluminum (Al) and iron (Fe) to again form less soluble compounds. Most of the other nutrients (micronutrients especially) tend to be less available when soil pH is above 7.5, and in fact are optimally available at a slightly acidic pH, e.g. 6.5 to 6.8. Web• Do not use a detergent that contains phosphate to clean the sample bottles. The phosphate in the detergent will contaminate the sample. • Analyze the samples as soon as possible for best results. • If immediate analysis is not possible, immediately filter and keep the samples at or below 6 °C (43 °F) for a maximum of 48 hours.
