PHOSPHATE MOBILIZATION BY ADDITION OF ORGANIC ACIDS IN TWO SOILS OF THE SOUTHERN GUINEA SAVANNA OF NIGRIA
ABSTRACT One mechanism by which plants can mobilize organic and inorganic forms of phosphorus (P) in soils is by exudation of low molecular weight organic acids. Laboratory and field trial were carried out during 2011 and 2012 cropping seasons to study the effects of additions of organic acids ( citric, oxalic and tartaric acids) on the mobilization of phosphate of soils from Minna and Mokwa, both in Southern Guinea Savanna ...
