Excerpt from Growing Plants Without Soil for Experimental Use In contrast, our objective has been to produce Vigorous, healthy, uniform plant material in regulated environments for experimental purposes. This publication is intended for those with some knowledge of plants who want to grow one or more species for experimental purposes, for demonstra tions in schools, or for science projects where limited facilities are available. Techniques and equipment are described that are used at the Metabolism and Radiation Research Laboratory, Fargo, N. Dak., to raise crop and weed species in the absence of soil for experiments in which pesti cides and their metabolites are applied to plants or plant parts, often in radioactive form. Some of the techniques have been adapted specifically for use with radioactive tracers, where consideration must be given to the absorptive properties of the containers and their disposability or ease of decontamination.
