Installation for perennial vegetation of terrace or roof in building, has control unit controlling irrigation device, so that vegetation substrate has moisture included in range of values

摘要

The installation has a vegetation substrate (17) comprising a puzzalona layer (19), where sedum type plants (21) are planted in the vegetation substrate. A control unit controls an irrigation device and a fertilizer supplying device, so that the vegetation substrate has moisture included in a range of values, and salinity comprised in an interval of values. The irrigation device and the fertilizer supplying device are connected to a moisture measuring system. The salinity of the vegetable substrate is evaluated using a sensor marketed under the name of TRISCAN(RTM: salinity sensor).
