“…Additionally, the addition of 14-25% volume of compost to these peat-based media obviously favored plant growth, especially of more-salt sensitive plants like Salvia. This was further reported by Lamanna et al (1991) for most of the ten studied ornmental plants grown in all mixtures of compost and peat as well as reducing peat volume to 25% compost by volume which was considered as a standard substrate having better plant quality than singular peat or compost.…”

Composting has been considerably recognized as a viable management method for solid organic wastes aimed at recycling of its end-product as a potting substrate for ornamental plants. Pelargonium and Salvia as salt-sensitive plants were grown in the mixture of compost (75, 50, 25% by volume) and additives (Hygromull, Cocofiber and SPS-standard soil type 73 with 70% peat and 30% clay). Since plants may suffer from a high salt content, thus in a further experiment compost was added as a partial substitute for peat. The results of the first pot experiment reveal that the large percentage of compost in the substrate had negative effects on plant growth and nutrient uptake (N, P, K and Na). Both yield formation and nutrient uptake significantly increased and almost gained levels of those in the control in the second pot experiment when plants were grown in peat-based substrates. Especially, the growth of Salvia was significantly improved. Consequently, the compost-based media (> 50% volume of compost) cannot be recommended for salt sensitive ornamental plants, while less than 25% of compost incorporated into peat creates peat-based substrates which reasonably enhanced growth of Pelargonium and Salvia.

“…Transplanting to soil was carried out after 0 (without culture in elongation media), 10 and 30 days in pots with soil mixture: 2 parts peat humus to 1 part perlite (Lamanna et al, 1991) to facilitate water uptake and aeration. The plants were placed under a plastic sheet and were protected from direct sun light until they were well established.…”

In order to optimize shoot regeneration in Kalanchoe¨blossfeldiana, leaf and internode explants of seven cultivars including one inter-specific were studied. The effects of various combinations of a-naphthalene acetic acid (NAA) (0, 0.57 M) and thidiazuron (TDZ) (0, 0.45, 4.5, 22.5, 67.5 lM) on MS medium were examined. In all cultivars shoot regeneration frequency and number of shoots per explant were enhanced by increasing TDZ concentration. Supplementing the media with NAA did not improve shoot regeneration. Maximum regeneration frequency and optimum concentration of TDZ for shoot regeneration depended significantly on the cultivar. Internode explants, but not leaf explants, of some cultivars, were able to produce adventitious shoots without treatment with growth regulator.

“…Expanded clay is obtained by treating clay powder at about 700 C. Stable aggregates are formed, and, depending on the used clay material, they have variable values with regard to CEC, pH and bulk density (Table 4.3). Expanded clay can be used in mixtures with organic materials in the amounts of about 10-35% by volume, to which it provides more aeration and drainage (Lamanna et al 1990). Expanded clays with pH values above 7.0 are not suitable for use in soilless systems.…”

Hydroponics is a method to grow crops without soil, and as such, these systems are added to aquaculture components to create aquaponics systems. Thus, together with the recirculating aquaculture system (RAS), hydroponic production forms a key part of the aqua-agricultural system of aquaponics. Many different existing hydroponic technologies can be applied when designing aquaponics systems. This depends on the environmental and financial circumstances, the type of crop that is cultivated and the available space. This chapter provides an overview of different hydroponic types, including substrates, nutrients and nutrient solutions, and disinfection methods of the recirculating nutrient solutions.
