Trichloroethylene (TCE) was widely used as an industrial solvent and degreasing agent for most of the twentieth century. It is now a widespread groundwater contaminant. Phytoremediation may be a cost-effective cleanup method for TCEii contaminated so

Hydroponics/Soilless Media
High root zone pH reduces nutrient availability and high alkalinity water is strongly buffered around an alkaline pH. Soilless media can be altered to improve nutrient availability. This study was conducted to optimize the composition of soilless med

For studies of root growth and morphology, an ideal containerized plant culture system should provide: 1) adequate nutrients, water and oxygen; 2) appropriate mechanical impedance to root elongation; 3) adequate depth to prevent root binding; and 4)

Why Soil Columns? In the field of plant research it is often desirable to grow plants under controlled conditions to minimize environmental variability from one treatment to the next. The desired control can be achieved by growing plants in container

Phytoremediation
Potential factors impacting tree and fruit concentrations include the above ground variables of tree type, tree age/size, irrigation patterns, time of season and number of fruit and the below ground variables of TCE groundwater concentration, depth t

Power loss is a common failure in controlled environments. The duration of power loss can be several days – and even weeks – in space environments. Long-duration power loss and the resulting darkness can cause plants to die unless remedial measur

Plant metabolism and growth are reduced in low temperature. As metabolism slows, energy requirements are reduced and less light is needed. The temperature should be maintained above the chilling temperature for the plant, which is species dependent.

We have sought to optimize conditions for crop yield for many years, but optimal conditions will not always be cost effective. More importantly, environmental control systems routinely fail, and we need to learn how to gracefully recover from these f
