Introduction
Phosphorus (P) is a major plant nutrient, applied as an inorganic fertiliser to much of the industrialised world to sustain agricultural productivity. However, the effectiveness of P fertiliser application is compromised in acid soils, due to increased P sorption through solid phase adsorption and precipitation reactions (White 1980). This is of global concern, as soil acidity affects up to 50% of the potentially arable land throughout the world (vonUexkull and Mutert 1995).
A large body of international literature supports the role of organic amendments in increasing the availability of soil P in agricultural systems (Iyamuremye and Dick ...
