12 Demonstration area 3 kk months and 2 years after establishment

13 3. Meadow Aim: Establishing abundant biodiversity supporting, low maintainance meadow Establishment Cropping the soil Fertilizing Seeding of meadow plant species

14 4. Maintainance 5 treatments of the grass No restoration Mineral fertilizer and lime Compost granule 0,3 l/m2 Compost granule 0,6 l/m2 Ecolan ash fertilizer

15 5. Green roof materials Growth substrate containing glass wool and compost soil Growth substrate boxes 30 degree angle facing south and north Vegetation 4 cm sedum grass mat

16 Green roof growth substrate 1/5 glass wool 2/5 Envor Biotech compost soil 2/5 Mineral soil from compost soil production process

17 Observations: Some vegation on the north side South side vegetation suffered from drought

18 Demos were introduced to public at the annual Lepaa exhibitions between The exhibitoins gather around visitors annually.
