Review: Modeling the Effects of Salinity and Sodicity in Agricultural Systems

“…The FAO model considers the threshold EC at which a specific crop begins to experience decreases in yield and the rate of decline thereafter (Allan et al, 1998). This approach is implemented in the AquaCrop model (Salman et al, 2021), which is designed to study the effects of water shortages on crop productivity.…”

An improved methodology for obtaining soil hydraulic properties by laboratory evaporation experiments

“…For the study and quantification of hydrological processes at a soil water balance scale, two mathematical approaches stand out. In the first place, the so-called bucket models, such as AquaCrop developed by FAO (Salman et al, 2021). Second, models based on the Richards differential equation can be used, requiring greater knowledge of soil hydraulic properties.…”
