Phosphate Soil Test
Location: Outside U.S.
Date: Summer 2012
I need to test the phosphate levels in soil next to a swamp. What chemicals would I need and how would I conduct this experiment?
Let me direct you to these scientists: http://www.sera17.ext.vt.edu/Documents/Methods_of_P_Analysis_2000.pdf
These are experts on P analysis in soils and waters of all types in the U.S..
Australia will have a similar group that publishes a "Methods" paper. These are usually scientists of an agricultural University. If you give them a call, they will probably help you with the methods, the chemicals, collections and analysis.
