The influence of the structure of soils for evaporation of soil surface

Abstract

We investigated the influence of the 6 artificial structures of soil for evaporation of soil surface.
We made them in Wagnels pot. Several pot is equivalent the state as follows.
No. 1 Nature condition.
No. 2 Immediately cultivating.
No. 3 After the cultivaion elapse a few days.
No. 4 Minute soil layer covers on the surface of the No. 1 pot.
No. 5 Minute soil layer covers on the surface of the No. 2 pot.
No. 6 Minute soil layer covers on the surface of the No. 3 pot.
Then we investigated the evaporation of soil surface about these pots in Summer, in case that the special time of the soil moisture, evaporation of the No. 2 pot is a little, as compared with the expect pots. But in winter is distinct.
