## 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

An acid-labile phosphate has been detected in alkaline extracts of four acid soils, and has been isolated and purified by ion-exchange and paper chromatography. Its chromatographic properties, its rate of hydrolysis in hydrochloric acid-and the infra-red spectrum of its barium salt show that it is i
