Is a program for irrigation equations.
Follow the site water2irrigation.
The equations that are performed are:
Ion Balance
T.H
Sodium Adsorption Ratio(SAR)
Sodium Adsorption Ratio Adjusted(Adj SAR)
Soluble Sodium Percentage(SSP)
Residual Sodium Carbonate(RSC)
Potential of Salinity(PS)
Magnesium Hazard(MH)
Permeability Index(PI)
Kelly's Ratio(KR)
It also checks the :
