A typical value of net daytime radiation in summer is +500 W/m? and that of the specific thermal flux of the soil is -10 W/m?. Therefore, the net heating is 490 W/m?

On a moist soil covered with plants, the typical values of the other terms of equation (7.3) would be the following:

Photosynthesis Q = 5 W/m?, Sensible heat flux, H = 100 W/m?, latent heat due to evaporation, LE = 400 W/m?.
