Plant uptake of band‐applied Mn from a Selma silt loam soil (pH 7.0) was enhanced by blending MnSO 4 ·H 2 O with each of four P sources in growth chamber tests. The relative value of ammonium polyphosphate (APP), monoammonium phosphate (MAP), diammonium phosphate (DAP), and monocalcium phosphate (MCP) in increasing Mn uptake by soybeans ( Glycine max ‘Hawkeye’ ) was MAP = APP≫MCP = DAP. There was a highly significant correlation between the plant concentration of Mn and P. Plant uptake of Mn was greatest when the pH of the P source was between 2 and 4. The amount of Mn which was absorbed per increment of P varied with the P source. In this experiment APP = MAP > MCP > DAP. Manganese movement and recovery (measured as exchangeable plus easily reducible) as influenced by P source decreased in the order: APP > MAP > MCP≫DAP. Manganese movement from phosphate mixtures was not detected when the soil pH was greater than 5.8.
