## Abstract A routine method has been developed for the determination of boron in plant and soil samples. The boron in the prepared samples is converted into BF~4~‐ in a H~2~SO~4~‐HF system, then extracted as a coloured complex with Azure‐C (or mthylne blue) into dichloroethane and finally determin
