2010 reviewed the physical and chemical characteristics of recycled soil ingredients and emphasize the need of combining soil material research with obser.
Soil type green roof.
Recently it was thought that the best soils for green roofs were engineered soils or pasteurized peat based soilless media with little emphasis on adapting it to local needs.
Green roof growing media is an integral part of a functioning.
That s why green roof substrate has considerably less organic matter than ordinary soil.
Soil structure for green roof media.
Green roofs or living roofs have become popular over the years.
Intensive green roofs require the deepest soil and have the greatest impact on the structural design but they also accommodate all types of plantings including large shrubs and trees.
Either that or the plants would perish from lack of growing medium.
The main advantage to this type of soil on a green roof is its light weight and ease of handling as it comes pre packaged in bales from a manufacturer.
Intensive systems allow the designer to create a park like setting so they are the best option for roof gardens that will be occupied.
When designing a green roof there are several factors to take into consideration.

The construction between the growing media and the roof structure varies but typically includes a drainage layer a root barrier and a waterproof membrane.
