How Efficient is my Irrigation System?

How efficient is the irrigation system?                                
    Ea = [Depth of water stored in the root zone (ds) x 100                            
                                                Depth of water pumped (dp) ]                            
    where:                            
    Ea  =   Average water application efficiency, %                            
    Depth of water stored in the root zone (ds)   =   Average depth of water stored in the root zone, inches                            
    Depth of water pumped (dp)   =   Average depth of water delivered from source, inches                            

    ds   =   [“After” reading – “Before” reading]                            
    where:                            
    ds = Depth of water stored in the root zone                            

    Water in root zone before irrigation    8.8    Inches                    
    Water in root zone after irrigation    9.6    Inches                    
    Depth of water increase in root zone    0.8    Inches                    
    Depth of water applied    1.0    Inches                    

    Application Efficiency    80%    Percent Efficiency
