p rocks have long been the principal source of materials for the production of soluble phosphates. Their use as a direct phosphate fertilizer however, has been limited because of their relative insolubility, and consequently many experiments have been conducted to determine the factors affecting the availability of phosphate rocks. This report is concerned only with experiments which were made to determine what influence the acidity of the soil might have on the availability of phosphate rocks from different sources and of varying chemical composition, particularly in their content of fluorine.
