Figure 8.1. The Periodic Table of Elements. Shaded areas identify the essential elements
Two ways to classify the essential elements 1. Classified by whether it is used in large or small amounts (Macronutrients or micronutrients) 2. Classified by its function in the plant What the element does in the plant)

Macronutrients and micronutrients a. Macronutrients are elements that are used in relatively large amounts(%or g/kg) B. Micronutrients are elements that are used in relatively small amounts(u g/g or mg/kg) The concentration of macronutrients in plant tissue is often more than 1000x greater than the concentration of micronutrients
