Abstract

The latest concept of soil available water for plants, integral water capacity, (IWC), is routinely computed by developing weighting functions (ωi(h)) for limiting factors for available water to plants, within a particular matric potential range (h) in the root medium. It is almost computed using the presumed ωi(h) created by the inventors of this concept and using soil properties without considering plant attributes. Up to now, no study has been done about using leaf water potential (LWP) of plants as a plant response criterion for the computation of IWC. LWP can consider the effects of soil, plant and atmospheric conditions on water availability for plants. In our last research, due to conducting the experiments in the greenhouse and the destructiveness of LWP measurement method, the number of data points was not enough to create appropriate weighting functions based on this index. We suggest more studies on this criterion for determining IWC in the field condition.
