Title: “Compost-based growing media for ornamental plant production” This work suggested the use composts obtained by olive mill (CS), green wastes (CV) or mixed green and urban sludge (CM), as substrates components for ornamental pot plant production. After the physical-chemical analyses, the growing media, obtained by mixing each compost in 30-50-70 % v/v, were used for the cultivation of Aloe vera (L.) Burm., Euphorbia x lomi Rauh, Rosmarinus officinalis L., Rhamnus alaternus L. and Hibiscus rosa-sinensis L.. The results showed a response highly dependent either on the plant species and the type and concentration of compost. The best compost for the plant growth was the green one at 50% concentration while the olive mill compost resulted not suitable for rosemary growth and may be used at 30% maximum on Euphorbia. Only on aloe, a very resistant species, both green and olive mill compost at 70% are recommended (peat-free substrates). It is even possible to use the compost CM at 50% maximum concentration for the production of rosemary, Rhamnus and Hibiscus plants. The use of compost allows to recycle organic materials and substitute peat in growing media with economic and environmental benefits.

Abstract
Title: “Compost-based growing media for ornamental plant production” This work suggested the use composts obtained by olive mill (CS), green wastes (CV) or mixed green and urban sludge (CM), as substrates components for ornamental pot plant production. After the physical-chemical analyses, the growing media, obtained by mixing each compost in 30-50-70 % v/v, were used for the cultivation of Aloe vera (L.) Burm., Euphorbia x lomi Rauh, Rosmarinus officinalis L., Rhamnus alaternus L. and Hibiscus rosa-sinensis L.. The results showed a response highly dependent either on the plant species and the type and concentration of compost. The best compost for the plant growth was the green one at 50% concentration while the olive mill compost resulted not suitable for rosemary growth and may be used at 30% maximum on Euphorbia. Only on aloe, a very resistant species, both green and olive mill compost at 70% are recommended (peat-free substrates). It is even possible to use the compost CM at 50% maximum concentration for the production of rosemary, Rhamnus and Hibiscus plants. The use of compost allows to recycle organic materials and substitute peat in growing media with economic and environmental benefits.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
