Flashcards in AC-Ch. 5 Tree Nutrition & Ferilization Deck (23)
Whitish or yellowish leaf discoloration caused by lack of Chlorophyll. Often caused by nutrient deficiency
Fertilizer containing the three primary elements: nitrogen, phosphorus, and potassium.
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
17 minerals essential to the growth and development of trees. These minerals are essential because plants cannot complete their life cycle without them.
Percentage of primary elements in a fertilizer
Injury to a plant resulting from excess fertilizer salts in the surrounding soil
Laboratory analysis of the mineral content of foliage
Device, capsule, or pellets inserted into the trees xylem system to treat or prevent diseases, disorders, or pest problems. Requires a relatively large diameter and deep hole in the trunk
Method of putting a liquid fertilizer or pesticide directly into the soil or a plant tissue.
Not containing carbon.
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
Essential element that is required by plants and relatively small quantities
In chemistry, a substance containing carbon. In an applied Arboricultural context, a substance, especially a fertilizer or pesticide, of animal or vegetable origin
Philosophy of basing fertilization recommendations on plant needs, which are primarily determined by soil or tissue testing.
Mineral element required in moderate amounts by plants
Fertilizer that is at least 50% water insoluble nitrogen. Rate of release may vary depending on soil moisture and temperature
Analysis of soil to determine pH, mineral composition, structure, and other characteristics.
Placement of fertilizer or other material below the soil surface
Conversion of a soild or liquid into a gas or vapor
Nitrogen fertilizer in a form that is not readily soluble in water
Water-insoluble nitrogen (WIN)
