How to Calculate Nitrogen Applied Through Irrigation Water

How Many Pounds of Nitrogen will I get when I Irrigate?

How many lbs of N will get when I irrigate?
                        
    lb./acre = 0.23 x Cw x Di                    
    where,                     
    Cw =   concentration of nitrate-nitrogen in the irrigation water (ppm)                    
    Di =   depth of irrigation water applied (inches)                    
                        
    Nitrate in Irr Water    20.0    ppm            
    Depth of application    1.0    Inches            
                        
    Nitrogen Applied     4.6    lbs/acre
