Shoot accumulation of mineral nutrients in maize plants (cv. Jessy) on two low P soils. as affected by MCP inoculation. Soil 1 (sandy-loam, pH 6.1, PCAL 7 mg kg−1 soil) and Soil 2 (clay-loam, pH 5.9, PCAL 20 mg kg−1 soil) receiving N fertilization in in form of Ca-nitrate (NO3−) or DMPP-stabilized ammonium (NH4+) and a moderate soluble P supply (30 mg P kg−1). Data represent means of five replicates. A One-way ANOVA with Tukey test was performed for data comparison. Different letters indicate significant differences between treatments (p < 0.05).
