The layer of fiber
soil consists of various types of organic and inorganic moisture
retaining agent for the establishment of broad leaf vegetation.
Once the vegetation system is established, the healthy and dense
vegetation will fully protect the soil surface from intensive evaporation
from the sunlight and strong wind. Normally, watering is not necessary
in the summer time, or if there is no rainfall in dry winter for
more than 30 days, once a month watering is required. |
