Effects of moisture level on nitrogen availability in tropical peat soil cultivated with oil palm (Elaeis guineensis Jacq.)

Nitrogen release from soil is controlled by the soil moisture. Soil incubation was conducted to evaluate the effect of different moisture condition (75%, 100% and 150%) on water holding capacity and fluctuating conditions between (150% and 100% water holding capacity) after application of urea and w...
