WebOur spectroradiometers allow for rapid field measurement of moisture in soil by collecting spectral information related to the main water features at 1450-1460nm and 1920-1930nm. In addition to providing a measurement of water content, they also deliver information that can be used to derive leaf and canopy water content. WebCalcium can be measured using murexide, a complexing agent. Phosphate by an ammonium molybdate method. See standard methods. Ammonium is sometimes done by evolution of ammonia into a weak acid buffer and titration to an endpoint. This is a titrimetric method. You can also use ninhydrin reagent IIRC for colorimetry.
