Fate and Form of Nitrogen under Different Soil Redox Status

The experiment sets out to investigate the effect of oxidation-reduction on nitrogen formsin soil. The trial was a 3 x 2 factorial experiment laid out in a Randomized Complete Block Design (RCBD) and replicated three times. Treatment consisted of two variables which are poultry manure at three levels (0t/ha, 6t/ha and 8t/ha) and water regime at two levels (field capacity and waterlogged).The combinations resulted into six (6) treatments resulting into three oxidation-reduction potential range [oxidized (>300), moderately reduced (-100 to 300), reduced (
