NUTRIENT CHARACTERISTICS OF COWDUNG AND COMPOSITE OF CHICKEN MANURE AND BREWERS' WASTESC.Y. JEJE, A.N. WINFUL AND A.A. SOWUNMI
Cowdung and composite of chicken manure and brewers' wastes were evaluated for nutrient characteristics. The concentrations of nitrate-nitrogen (NO3-N), ammonia nitrogen (NH3-N) and phosphate (PO43-) from cowdung (0.26±0.18, 0.13±0.18; 0.59±0.53, 0.30±0.14; 0.19±0.12, 0.27±0.11 mg/1) were lower compared with composite (0.20±0.80, 0.33±0.14; 0.96±0.55, 0.72±0.45; 0.30±0.13, 0.30±0.22 mg/1) for all trials. F-statistic indicated significant differences for the nutrients across treatments and water quality parameters except pH (F=1.40). Addition of brewers' wastes to chicken manure apparently delayed rate of nutrient exhaustion for the composite.
