Abstract
IN some calcareous grassland soils in County Galway, certain fertility problems have been encountered with particular regard to soil phosphorus. While ‘high’ or ‘very high’ values for readily soluble phosphorus were sometimes obtained by routine analytical procedures2, grazing and botanical observations indicated extreme phosphorus deficiency. Such observations were verified by herbage analyses, where figures of the order of 0.10–0.11 per cent of the dry matter were obtained.
