Much of the information on this website describes diseases but this section is devoted to problems associated with either excess levels of nutrients in the soil which leads to toxicity, or a lack of nutrient within the soil which leads to deficiencies within plants.

Mineral deficiency symptoms also depend on the mobility of the nutrient within the plant. If a nutrient can move freely from one part of a plant to another, then symptoms of the deficiency will appear first in older organs. Young, growing tissues have more “drawing power” than old tissues for nutrients in short supply.
