Seasonal Soil Moisture Characteristics of an Artificial Forest in a City

Soil and water environment of trees in an urbanized green area (III)

Abstract

This study was conducted to clarify the soil moisture environment in an artificial forest over the course of a year by observing the soil moisture conditions and water consumption properties. Locations where Abelias, Katuras, and Loropetalume chinensis Olives were planted were selected for study. The results are as follows.
The driest conditions were observed where Katsuras planted during summer, and the wettest conditions were observed where Loropetalume chinensis Olives planted.
The soil moisture conditions through the winter season were maintained to be over-wet in all places, so that the drainage should be necessary to improve the poor conditions.
Finally, the highest daily consumption was observed during July or August. On the other hand, the ratio of consumptive use in the lowest soil layer was the smallest, but the differences of that in other soil layers were not so clear.
