Languages of publication
Plant mineral elements play a special role in the maintenance of good health. Nigeria is rich in natural wealth and there is an ample scope to explore mineral constituents from the plant kingdom. Teak is an exotic tree in Nigeria but easily grows on almost all soil types in the country. This research aimed at comparatively investigating the macro nutrient status of both withered brown leaf and green leaf of teak from Onigambari plantation. The result of the analysis shows that Green T. grandis leaves contains Sodium 0.488/48.8%,Calcium 0.162/16.2%, Magnesium 0.034/3.4%, Potassium 0.065/6.5% and phosphorus 0.0006/0.06% respectively while the withered brown leaves contains Sodium 0.488/48.8%, Calcium 0.174/17.4%, Magnesium 0.034/3.4%, Potassium 0.046/4.6% and phosphorus 0.005/0.5% respectively. Also the trace elements contents of Green T. grandis leaves contains Iron 0.41/41%, Copper 0.067/6.7%, Manganese 0.010/1%, Zinc 0.005/0.5%, Lead 0.004/0.4%, Chromium 0.002/0.2%, Cadmium 0.00002/0.002% respectively. While the Withered brown T. grandis contains Iron 0.53/53%, Copper 0.064/6.4%, Manganese 0.014/1.4%, Zinc 0.006/0.6%, Lead 0.003/0.3%, Chromium 0.003/0.3%, Cadmium 0.0001/0.01% respectively. The result of this analysis shows that withered T. grandis leaves is a good source of iron, however both Green and withered T. grandis leaves are good sources of Na, Ca, Fe and Cu. The result also shows that both samples are non toxic due to the low amount of lead.
