COMPARING COPPER UPTAKE BETWEEN GARLIC AND DILL

Ground soil in the urban farming areas is naturally unfertilized and may have absorbed toxins due to industrial environmental factors. Decontaminating soil manually is very expensive, however, there is a method for removing harmful chemicals using plants. This process is called phytoremediation. Within the experiment described here, we have explored the uptake of copper by two spice plants, garlic and dill.  This experiment had two goals.  The first was to compare the copper uptake and plant growth of garlic and dill in soils with various concentrations of copper added.  The second was to compare the copper uptake and plant growth of garlic and dill  between fertilized and local soils with various concentrations of copper added. The hypothesis is that garlic will absorb more copper than the dill. Garlic and dill were planted, watered, monitored and after six weeks, were harvested.  The shoots were removed, measured, and examined, and two samples of each pot of soil were collected. One set of soil samples were sent out for analysis by an external lab. The other set was digested in the lab and analyzed by another method. The results will be presented and compared to previous work.
