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.
