Analysis of soil samples from the San Joaquin Valley of California

spectra for samples and standards are recorded on a 111-0 photographic emulsion.The transmissions of the boron line at 249.68 nm and the adjacent background are both read for samples and standards.Standards are then plotted and a calibration plot developed which is then used to quantitate the boron in samples. PRESENTATION OF RESULTSInformation on the analytical methods used and the lower limits of determination for each method and each element are presented in table 1. Table 2 provides information on the elements analyzed and the analytical limitations associated with those analyses.Table 3 contains information on the sample location and elemental composition of the sample.
