The exchange of water and carbon by crops in a mediterranean climate

  • J. L. Monteith
Article

Abstract

The amount of biomass accumulated by a crop stand per unit of water transpired is referred to as a Biomass Water Ratio (BWR). The paper is mainly concerned with the dependence of BWR on climatic factors, in particular, saturation vapour pressure deficit (D) and precipitation (P) with which D is highly correlated in a mediterranean climate. A method is outlined for estimating the amount of water evaporated from bare soil during the establishment phase of a crop as a fraction of total seasonal water use. A simple model is derived for the BWR as a function of climate and of two stomatal parameters derived from a relation between stomatal conductance and transpiration. Values of BWR are presented for three contrasting stations in Israel and are shown to be strongly correlated with D and therefore with P. The model is combined with an empirical relation between the Priestley-Taylor coefficient and surface resistance in order to establish a new relation between BWR and resistance and to demonstrate that BWR × D is almost independent of resistance above 100 sm−1.
