Mar. 15, 1924 Elemental Composition of the Corn Plant 847 pulverized for chemical analysis. In the preparation of material the husks were placed with the leaves and the tassel with the stem. The cobs of the five plants were ground together and the analysis made of this mixture, so that the variation in the composition of these organs

But also, toxic elements can also be found in plants, primarily through uptake from the soil, water, and fertilizer. Such an analysis is usually conducted by ICP, which requires acid digestion. This report describes X-ray fluorescence spectrometry as a suitable alternative method to determine nutrient and trace element content in plant material.

The essential mineral elements are: . Nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, chlorine, iron, manganese, zinc, copper, molybdenum, and nickel. In addition to the essential mineral elements are the beneficial elements, elements which promote plant growth in many plant species but are not absolutely necessary for completion of the plant life cycle, or fail to meet ...
