The absorption of the solar energy on the Earth’s surface covered by plants and the convection of the sensible and latent heat from the plants to the boundary layer of the atmosphere (dry and moist convection) were evaluated in the experimental area of Zábrod Meadow in the Šumava Mts during the growing seasons 1983–2000. It was found that the average rate of entropy production by absorption of solar radiation 652.4 mW/m2 K corresponds to the planetary value of 561 mW/m2 K. The average rate of entropy production by moist convection 22.9 mW/m2 K is very close to the planetary value of 23 mW/m2 K. On the other hand, the average rate of entropy production by dry convection of 27.1 mW/m2 K is 10 times greater than the planetary value of about 2 mW/m2 K.
