Porous ceramic granules (PCGs) present an interconnected pores architecture, which mimics the spatial arrangement of the pore spaces and of the solid particles, mineral and/or organic, in the soil. More than 2/3 of the volumes of the ceramic granules used as soil improvers are pores of different sizes – macro, micro and nanopores. Around one half of these pores are capillary pores, which retain and slowly release water and mineral nutrients. The other half of the pores are non-capillary pores, retaining gases and supporting soil aeration. This PCGs porous structure, related to the efficiency as soil improver, is highly compaction-resistant, making PCGs an effective soil conditioner for cultivated plants that support high traffic, such as turf and ornamental garden plants. This paper reviews the use of porous ceramic granules as inorganic soil improver for horticultural plants.
