Different rates of herbicides and plant growth regulators (PGRs) will be applied to container-grown plants produced in various soilless substrates. Using a nutrient recovery system, the effluent and/or substrate at various depths will be collected and analyzed to determine the rate of leaching. In addition, applied radio-labeled herbicides will be analyzed to determine efficacy in these alternative substrates, especially in the root zone.
