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. trial was a 3 x 2 factorial laid in Randomized Complete Block Design (RCBD) and replicated three times. Treatment consisted two variables which are poultry manure at levels (0t/ha, 6t/ha 8t/ha) water regime (field capacity waterlogged).The combinations resulted into six (6) treatments resulting potential range [oxidized (>300), moderately reduced (-100 300), (<-100)]. Data collected pH, Eh, Total nitrogen, Organic matter,NO3—N NH4+-N. were subjected Analysis variance (ANOVA) while mean separated using Tukey Honesty Significant Difference (HSD) Test. Graphs generated Microsoft excel. result showed that under oxidize condition is majorly nitrate form ammonia. However, soil had highest total content. This attributed fact both forms present as accumulation NH4+ progress nitrification process. It concluded fate also depends status
