Abstract: A soilless system for high density plant growth includes a greenhouse structure; at least one elongate support member arranged substantially vertically in the greenhouse structure, the support member having a body having a flow channel defined therein; and a plurality of vertically spaced apart receptacles angularly disposed to the vertical axis of the body to receive a plant therein, the receptacles being in fluid communication with the flow channel; a fluid supply system in fluid communication with the flow channel to supply a fluid stream to the flow channel; and a fluid collection system to collect residual fluid that has flowed through the flow channel.

Abstract: A soilless plant cultivating container includes an elongate body of generally wave shaped form and having a flow channel defined therethrough; and a receptacle defined in a sidewall of the body in fluid communication with the flow channel to receive and support a plant therein.

Abstract: The invention provides the activation, refining and stabilization of oil shale. The stabilization may be performed by recirculative extraction, the activation by electromagnetic irradiation, steam, or by an inorganic base, and the refining by ion beam irradiation. The thus processed oil shale may be used to adsorb organic and inorganic contaminants from a variety of materials include materials of vegetable origin.

Abstract: The invention provides a process for preparing a soil improving and fertilising composition from fertiliser and crosslinked copolymer, the process including imparting an electrical charge to at least one of said copolymer and the fertiliser and bringing said copolymer and fertiliser into intimate contact with each other. The fertiliser and crosslinked copolymer are believed to be mechanically fused to form the composition. The invention extends to a composition and to an agricultural or horticultural method using the composition.
