Abstract

A general method for determining the CO flux at the soil surface and the top of a crop is given. Some comparisons are made in order to illustrate the various means at present used to calculate the net photosynthesis. Results obtained during the growth period of a corn crop are principally analysed as a function of two climatic variables: the global radiation and the CO exchange coefficient. The analysis is also used to calculate from climatic data the daily photosynthesis and the total production for two monthly periods. Values so obtained are in good agreement with direct measurements of total dry matter production if respiration during the growing period is taken into account.
