Abstract Waxoline purple AS has been established as an efficient colorimetric reagent for the determination of boron in 84% sulphuric acid. Data are presented showing the loss of boron during the orthodox ashing techniques of both plant residues and soil extracts. Conditions of ignition have been established whereby it is possible to check the relative boron status of any crop or soil when compared against standards from the same crop or similar soil type known to have a satisfactory boron status.
