Mathematics and Its Applicationsmportant under cover, especially in plastic houses where air exchange is normally restricted in order to raise temperatures in a cold climate, and as a result then carbon dioxide concentration falls below the outside level during the daytime. Sometimes, therefore, CO. enrichment is conducted in plastic houses.

https://doi.org/10.1007/978-94-015-9878-1 flow in soil is independent of heat flow, as we assumed in the chapter on heat flow analysis. Furthermore, we will focus only on vapor movement in the present chapter, because in most cases water flow is assumed to occur in parallel with water vapor flow and they are combined. This can be condensed into what is the diffusion coefficient for both.

Heat Balance of Bare Ground,yer, neglecting water movement in the soil. At the surface, not only sensible but also latent heat transfer occurs. These heat flows from the surface to the ambient air are by convection. Therefore, three types of heat transfer are at work in a soil-air system, as shown in Fig. 4.1.

Temperature Environment under Cover, an important factor in getting a large amount of energy into the soil surface. At night, the energy source is thus the soil layer. The main heat loss from the surface is due to long wave radiation, and the emissivity of the cover is a key factor in this.
