Whitish or yellowish leaf discoloration caused by lack of Chlorophyll. Often caused by nutrient deficiency
Chlorosis

Complete fertilizer
Applying fertilizer by drilling holes in the soil within the root zone
Drill-hole method of fertilization
Imaginary line defined by the branch spread of a single plant or group of plants
drip line
17 minerals essential to the growth and development of trees. These minerals are essential because plants cannot complete their life cycle without them.
Essential elements

Fertilizer analysis
Injury to a plant resulting from excess fertilizer salts in the surrounding soil
Fertilizer burn
Laboratory analysis of the mineral content of foliage
Foliar analysis

Implant
Method of putting a liquid fertilizer or pesticide directly into the soil or a plant tissue.
Injection

Inorganic
Applying liquid formulations of fertilizer by injection into the root zone on the tree
Liquid injection fertilization
Essential element that is required by plants and relatively large quantities
Macro nutrient
Essential element that is required by plants and relatively small quantities
Micronutrient
