•Fertilizer N recovery efficiency (FNRE) in maize varies among different soils.•Soil pH and organic matter drive variations in maize FNRE.•Optimal soil pH for maize FNRE is around 6.50–6.62.•Optimal soil organic matter for maize FNRE is around 35.25–46.90 g kg−1.•Soil dissimilatory nitrate reduction...
