Maize grows best on deep, well-drained, fertile soils, and where total seasonal rainfall exceeds 500 mm. Maize is reasonably tolerant to soil acidity, but if the soil is very acid, liming will improve the soil and enhance maize yields. Maize is susceptible to both drought and waterlogging. Thus, poorly drained soils should be avoided, unless practices like ridge tillage,
This field trial's goal was to determine the best coating-ratio and the N level for maize, compared with fertigation, and to test the influence of CRF application methods
