In this work sixteen plants locally grown in the sandy soil of central Saudi Arabia in Al-Qassim region have been investigated for their iron (Fe) content using computerized Shimadzu AA 620 spectrophotometer. This particular soil being devoid of minerals both macro- and micronutrients receives them from the added preparations of different types of chemicals. It was found that all 16 plants investigated in this work contained substantial amounts of Fe as is reflected by the healthy growth of the plants and by the actual amounts of Fe being determined for each of these plants. Sabanikh (Spinacia oleracea), carrot leaves (Duacus carota) and Basal (Allium cepa) contained 1000, 860 and 710 ppm respectively. The relatively low Fe content of pumpkin (Cucurbita spp < /em>) of 120 ppm may be due to the high content of carbohydrates in the plant.
