Recognizing the importance of plant and soil science

Recognizing the Importance of Plant and Soil Science


Objectives

Objectives

  • Identify the various roles of plants in everyday life;

  • Identify the various segments of plant and soil science; and

  • Identify important types of plants and their uses.


Roles of plants in e veryday life

Roles of Plants in Everyday Life

  • Why do we need plants?

    • Food

    • Food Chain

    • Oxygen

  • Let’s list the most important uses of plants


Roles of plants in everyday life

Roles of Plants in Everyday Life

  • Edible Plants

    • Whole plants

    • Portions of plants

  • The most important – can you guess?

    • Grains

      • Wheat, rice, corn, barley

  • About 88% of the world’s total caloric intake comes from plant food sources

  • About 80% of the world’s protein intake comes from plant food sources

  • Some plants are used to make beverages


Roles of plants in everyday life1

Roles of Plants in Everyday Life

  • Industrial Uses

    • Wood

      • What is it use for?

    • Fiber

      • What is it use for?

    • Chemicals

      • What is it use for?

    • Rubber

      • What is it use for?


Roles of plants in everyday life2

Roles of Plants in Everyday Life

  • Medicinal uses

    • Plants have played a very important role in developing medicines

  • Scientists are still studying plants to understand the chemical compounds found within them

  • Some believe that some of our most deadly diseases will be cured by an undiscovered plant compound


Roles of plants in everyday life3

Roles of Plants in Everyday Life

  • Oils

    • Many plants store oils as food in the seed or plant itself

  • Some oils are used to make or produce food for humans

  • Others are used in industry

  • What are some oil producing plants?


Segments of plant and soil science

Segments of Plant and Soil Science

  • What makes up the top layer of the earth’s crust?

    • Soil

  • What is soil science?

    • Study of structure, composition, fertility, use, and protection of soil.

  • What is plant science?

    • Study of structure, functions, growth, and protection of plants

    • Can be divided into 3 categories


Segments of plant and soil science1

Segments of Plant and Soil Science

  • 3 categories of Plant Science

    • Field Crops

    • Forestry

    • Horticulture Crops


Segments of plant and soil science2

Segments of Plant and Soil Science

  • Field Crops

    • Plants (other than fruits and veggies) grown in large fields and are used for agricultural purposes

      • oil, fiber, grain, etc…

    • Corn and wheat are often grown for their seed but other parts of the plant can be used

    • Agronomyspecializes in field crops and their relations with the soil


Segments of plant and soil science3

Segments of Plant and Soil Science

  • Forestry

    • Science of growing trees and producing wood products

      • What are some wood products?

    • Tree Farms are cultured forests that are carefully planned


Segments of plant and soil science4

Segments of Plant and Soil Science

  • Horticulture Crops

    • Grown for food, comfort, and beauty

    • Two major areas of horticulture are

      • Ornamental Horticulture

      • Food Crop Horticulture


Segments of plant and soil science5

Segments of Plant and Soil Science

  • Ornamental Horticulture

    • Plants used for their beauty

    • Floriculture

      • Use of plants for the flowers and foliage

        • Foliage is the stems and leaves


Segments of plant and soil science6

Segments of Plant and Soil Science

  • Ornamental Horticulture

    • Landscape Horticulture

      • Growing and using plants to make outdoor environment more appealing

      • Shrubs, flowering plants, lawn areas


Segments of plant and soil science7

Segments of Plant and Soil Science

  • Ornamental Horticulture

    • Interiorscaping

      • Plants inside buildings to create an attractive indoor environment


Segments of plant and soil science8

Segments of Plant and Soil Science

  • Food Crop Horticulture

    • Growing plants for food

    • Includes orchards and gardens


Food crop horticulture

Food Crop Horticulture

  • Food Crop Horticulture

    • Olericulture

      • Science of producing vegetable crops

    • Pomology

      • Science of producing fruit and nuts


Today s assignment need a separate sheet of paper

Today’s Assignment(Need a separate sheet of paper)

  • For each area of plant science, list 5 crops that are grown.

    • Field crops, Floriculture, Landscape, Interiorscape, Olericulture, Pomology, Forestry.

  • Circle the plant in each section that you would be most interested in learning about.

  • Choose 2 areas of plant science that interest you and write a paragraph about each one explaining why you are interested, what kind of crops do you want to grow, etc…


Types of plants and their uses

Types of Plants and Their Uses

  • Very few wild plants play an important role in everyday life

  • Plant Domestication is removing plants from their native environment and growing them under controlled conditions


Types of plants and their uses1

Types of Plants and Their Uses

  • Seven categories of important domesticated plants in North America

    • They are all field and horticulture crops


Types of plants and their uses2

Types of Plants and Their Uses

  • Grain Crops

    • Plants grown for an edible seed

      • Does not include nuts

    • Cereal Grains is the seed of grass-type plants grown for food and animal feed


Types of plants and their uses3

Types of Plants and Their Uses

  • Sugar Crops

    • Source of sucrose

      • Sucrose is a carbohydrate that provides energy

    • Major sugar crops

      • Sugar beets

      • Sugar cane

    • Can you think of other sources of sugar?


Types of plants and their uses4

Types of Plants and Their Uses

  • Oil Crops

    • Grown for the vegetable oil in their seeds and fruits

    • Major oil crops for the U.S. are:

      • Soybeans

      • Cotton

      • Canola

      • Corn


Types of plants and their uses5

Types of Plants and Their Uses

  • Fiber Crops

    • Grown for the fiber harvested from their fruit, stems, or leaves

    • What are fibers?

      • Threadlike structures used to manufacture cloth, paper, and other things

    • What is the major fiber crop?

      • Cotton

      • Others include flax, hemp, jute, and ramie


Types of plants and their uses6

Types of Plants and Their Uses

  • Vegetable, Fruit, and Nut Crops

    • Primarily grown for food


Types of plants and their uses7

Types of Plants and Their Uses

  • Forage Crops

    • Forage: leaves and stems of plants used for animal feed

    • Primarily grasses or legumes

      • Grasses are non-woody plants that have parallel veins in their leaves

      • Legumes are broad-leaf plants that have the potential to fix nitrogen from air in the soil

    • Forages can be grazed or harvested and stored for later feeding


Types of plants and their uses8

Types of Plants and Their Uses

  • Ornamental and Turf Crops

    • Ornamental Crops: flowers, shrubs, vines, and other plants grown for beauty and appeal

    • Turf Crops: provide a pleasing look and protect the soil

      • Usually grasses

      • What are they protecting the soil from?


Types of plants and their uses9

Types of Plants and Their Uses

  • Other crops

    • These just don’t fit in any other group

    • Beverages

      • Coffee, tea, use your imagination

      • Herbs, spices, or medicine
