Methods for analysis of soil samples

摘要: The present invention relates to methods for the preparation and analysis of soil samples determine presence, concentration and/or volume at least one component in a sample, including steps extracting from sample by use aqueous solution and, depending on element, adding complexing agent mixture. resulting mixture is then able be analyzed via NIR or UV/Vis spectrometry as component, not normally detectable spectrometry, converted into an accurately measurable form. may used obtain test result site within time period 10 45 minutes rather than days using methods.
