Effects of recycled materials added to the substrate on nursery trees

Transplant can be a shock for plants, especially when they are moved from the nursery, where the environmental conditions are very favourable, to urbanised areas, where resources and maintenance are scarce. Moreover, some characteristics of urban soils, such as alkaline pH and compaction, make it difficult for trees to adapt. Recycled organic material (compost) added as mulch to trees plantings is effective in contrasting compaction in urban soils.
