Calcium, (Ca) trace element (Mn, Cu, Fe, Zn) and moisture contents of different varieties of cereals and pulses are reported. The nutrient densities (mg/100 calories) of Ca and the 4 trace elements also are calculated. Cereal concentration of Ca, Mn, Fe, Cu, and Zn were approximately 45-287, 0.6-3, 9-4, 0.3-0.7, and 1.6-3 mg/100 g dry matter, while the respective nutrient densities ranged from about 13-82, 0.2-0.9, 1.2-2.6, 0.1-0.2, and 0.5-0.9 mg/100 calories. Legume concentration of Ca, Mn, Fe, Cu, and Zn equalled approximately 110-281, 0.9-1.8, 6,8-13, 0.6-1.8, and 2-4 mg/100 g dry matter, respectively, while the nutrient densities ranged from about 32-78, 0.2-0.5, 2.0-3.8, 0.15-0.24, and 0.5-1.2 mg/100 calories. While these cereals and legumes are relatively good sources of these trace elements, the availability of the elements is affected by the presence of high phytic acid and fiber levels. (wz)
