A. Aerobic growth on domestic wastewater with ammonia nitrogen as the nitrogen source. The yield is 0.60 mg biomass COD formed/mg substrate COD removed.
2. Growth on a carbohydrate with nitrate as the terminal electron acceptor and ammonia as the nitrogen source. The yield is 0.50 mg biomass COD formed/mg substrate COD used? Please need your help. Thanks
please help me with some calculations.
A researcher who is doing an experiment on fertilizer rate wants to apply nitrogen (N) at 50 kg per hectare and phosphorus (P) at 50 kg per hectare. Assume Urea and Di-ammonium Phosphate (DAP) fertilizers are the only nitrogen and phosphorus fertilizers available in store. The experimental plot size of the researcher is 2000 m2. Calculate the amount of urea and DAP fertilizers that the researcher has to apply to 2000 m2 experimental plot size. Assume N is 46% in urea and 18% in DAP and P2O5 is 46% in DAP fertilizer. The atomic weight of P is 31 and O is 16.
