Flashcards in AC-Ch. 5 Tree Nutrition & Ferilization Deck (23)
1

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

Chlorosis

2

Fertilizer containing the three primary elements: nitrogen, phosphorus, and potassium.

Complete fertilizer

3

Applying fertilizer by drilling holes in the soil within the root zone

Drill-hole method of fertilization

4

Imaginary line defined by the branch spread of a single plant or group of plants

drip line

5

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

6

Percentage of primary elements in a fertilizer

Fertilizer analysis

7

Injury to a plant resulting from excess fertilizer salts in the surrounding soil

Fertilizer burn

8

Laboratory analysis of the mineral content of foliage

Foliar analysis

9

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

Implant

10

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

Injection

11

Not containing carbon.

Inorganic

12

Applying liquid formulations of fertilizer by injection into the root zone on the tree

Liquid injection fertilization

13

Essential element that is required by plants and relatively large quantities

Macro nutrient

14

Essential element that is required by plants and relatively small quantities

Micronutrient

15

In chemistry, a substance containing carbon. In an applied Arboricultural context, a substance, especially a fertilizer or pesticide, of animal or vegetable origin

Organic

16

Philosophy of basing fertilization recommendations on plant needs, which are primarily determined by soil or tissue testing.

Prescription fertilization

17

Mineral element required in moderate amounts by plants

Secondary nutrient

18

Fertilizer that is at least 50% water insoluble nitrogen. Rate of release may vary depending on soil moisture and temperature

Slow-release fertilizer

19

Analysis of soil to determine pH, mineral composition, structure, and other characteristics.

Soil analysis

20

Placement of fertilizer or other material below the soil surface

Subsurface application

21

Conversion of a soild or liquid into a gas or vapor

Volatilization

22

Nitrogen fertilizer in a form that is not readily soluble in water

Water-insoluble nitrogen (WIN)

23

Chemical compound that keeps plant nutrients soluble and available for plant absorption over a broad range of pH. Usually iron

Chelate
