Little or no work is done on the effect of fertilizer injection in a concentrated band on soil P chemistry. This study is conducted to assess the behaviour of P in the vicinity of the point application of  manure and inorganic fertilizer P in a band, as assessed by macroscopic-scale studies and synchrotron radiation techniques. The objective of this work was to reveal the spatial distribution and chemical speciation of P form applied in a band. The transformation of P applied to soil in band is affected by P source (manure versus fertilizer) because of differences in solubility and the ability of organic ligands present in manure to block P adsorption sites.
