apply nitrogen(N) at 50kg per hectare and phosphorus(P) per hectare. assume urea and Di-ammonium phosphate(DAP) fertilizers are the only nitrogen and phosphorus fertilizers available in the store. the experimental plot size of the researcher is 2000m^2. calculate the amount of urea and DAP fertilizers that the researcher has apply to to 2000m^2 experimental plot size. assume N is 46%in urea and and 18% in DAP and P2 O5 is 46% in DAP fertilizer. the atomic weight of P is 31 and O is 16​
