Abstract:
Soilless culture methods offer unique benefits such as capabilities to control water availability, pH, and nutrient concentrations in the root zone. At the same time, there are higher risks because of the smaller root system and low buffering capacity for water and nutrients and because of the increased risk of exposure to extreme ambient temperatures. This chapter exemplifies nutritional issues of substrate-grown plants and discusses differences between fertilization/nutrition of soil-grown plants and of soilless-grown ones. It focuses on the pH effects on plant root functions and on availability of specific nutrients. It presents the nutritional requirements of soilless-grown crops and illustrates the impacts of the NH4/NO3 ratio in the irrigation water on rhizosphere-pH and on the development of soilless-grown plants. It also discusses the integrated effect of irrigation frequency and nutrient availability on crop growth. Following this, it presents an account of the crop responses to changes in the electrical conductivity of the root-zone solution and to the ionic composition of the water, in soilless culture. Furthermore, it describes the mode of fertilisation and the potential nutrient sources and discusses possible interactions among various fertilizers, and between the roots, the solution, and the substrate, including the effects of the medium. © 2008 Elsevier B.V.
