Ashcroft, 2006 ). However, plant densities and arrangements in hydroponics are different from field production ( Resh, 2004 ), and sizing the hydroponic sub-system may depend on plant type, density, and arrangement and their effect on water requirements

Aquaponics incorporates hydroponics (soilless plant production) and aquaculture (fish production) into a closed-loop, recirculating system ( Rakocy et al., 2006 ). Waste from the fish production provides the primary nutrients for the crop plants

Current recommendations for sufficiency of nutrients in soil-less media for container grown nursery crops have been based on weak acid extraction and pour through sampling of media. Since the concentration of nutrients found in pour through samples are similar to those available in the media solution, sufficiency levels as determined by hydroponics studies have also been considered to be applicable to plants grown in a solid medium such as pine bark. Many variables, however, may affect nutrient availability in a solid medium which are not the same as those in a well-stirred hydroponics system. Objectives of this experiment were to compare growth and nutrient uptake patterns of Euonymous kiautschovica `Manhattan' and Prunus persica `Jefferson' grown in a pine bark/sand medium or a hydroponics system. Quantitative growth characteristics, depletion rates of nutrients in solution, concentration of ions in pour through samples, and tissue levels of N, P, K, Ca, and Mg will be reported.

Hydroponics is the method of growing plants under soilless conditions with nutrients, water, and an inert medium ( Savvas, 2003 ). Systems can be circulating, in which the nutrient solution is recirculated and nutrient levels are manipulated, or
