3 Soil Water Resources Use Limit by Plant
The mathematical model for calculating Soil Water Resources Use Limit by Plant (SWRULP) was showing as following:
SWRULP=
Here, SWRULP is Use Limit of Soil Water by Plant, expressed in mm. MID is maximum infiltration depth. Ow is wilting coefficient at soil depth of i, the symbol i is the number of soil layer and D is the thickness of the soil at i soil layer
