Fig. 1. (a) Total P and (b) percentage of P from fertilizer in soil sections collected at different distances from the point of fertilizer application. The percentage of P from fertilizer in each section (%Pf S1–4) was calculated as follows: %Pf Si = [(Pf)Si x Wi]/
i = 1–4 [(Pf)Si x Wi] where, i is the soil section (1–4), (Pf)Si and Wi are the concentration of fertilizer P and the soil weight of each section respectively. (Pf)Si is calculated by subtracting the P concentration of the untreated soil (236 mg kg–1) from the concentration of the fertilized soil. Error bars represent standard errors of five replicates. LSD for fertilizer treatment x soil section was (a) 68 and (b) 1.3.
