Plant production in hydroponics and soilless culture is rapidly expanding throughout the world, raising a great interest in the scientific community. This book covers both theoretical and practical aspects of hydroponics (growing plants without the use of soil), including the properties of the various soilless media and how these properties affect plant performance in relation to basic horticultural operations, such as irrigation and fertilization. The authors also discuss recycled, no-discharge systems including salinity and nutrition management and pathogen eradication.
