Abstract-The study was carried out to investigate the effect of phosphate fertilizer application on manganese (Mn) adsorption. Composite sandy loam and loam soil samples (0-20 cm) were collected from Dalori and Gongulong and analysed for their texture and chemical properties. Mn adsorption experiment was carried out. Loamy soil collected at Gongulong was moderately acidic in reaction, moderate in electrical conductivity (EC), high in base saturation, moderate in organic carbon, low in available phosphorus, and low in DTPA extractable Mn. While sandy loam soil collected at Dalori is neutral in reaction, low in EC, high in base saturation, low in organic carbon and low in DTPA extractable Mn. For sandy loam soil, there was no definite trend in the equilibrium Mn concentration with and without phosphate (P) fertilizer treatment, with increasing application of Mn concentrations. There was however no difference in the amount of Mn adsorbed by the soils when P fertilizer was added. For loam soil, there was no definite trend in the equilibrium Mn ion concentration of the soils with increasing application of Mn levels to the soils with and without P fertilizer treatments. There was however an increase in the amount of Mn adsorbed by the soils. There was no difference in the amount of Mn adsorbed by the soils when P fertilizer was applied. Data were fitted into Langmuir and Freundlich equations. Loam soil without P conformed to Langmuir equation, while for Freundlich isotherm, loam soil with P treatment conformed to the equation. The results showed that maximum adsorption (b) for loam soil without P was 0.99mg/g and binding strength (K) of -214.92 ml/µg. While for Freundlich, the adsorption constant (K) and (n) were 1.28 and -0.21 respectively. This study have revealed that there is no observable effect on the amount of Mn adsorbed by the soils after P fertilizer was applied and on the other hand do not reduce bioavailability of Mn in soil.
