Due to the ever-growing human population, the demand for higher crop production burdens farmers to mass produce. In order to produce a high yield, crops require several non-mineral, macronutrients and micronutrients in the soil to flourish. In this study, the micronutrients that are the subject of interest are copper and iron. The recommended levels for these micronutrients in soil range from 29-50 ppm iron and 1-3 ppm copper. Utilizing flame atomic absorption spectrometry (FAAS), the quantity of these essential micronutrients were determined from a variety of fields on the Willis family farm in southern Georgia. The soil was digested using concentrated hydrochloric acid and a series of dilutions were performed followed by FAAS analysis. Results were compared to literature values for soils in Georgia.
