HORT 100: Plants, Landscapes, and the Environment  


What is Reservoir?



Mini-Exam 1 Study Guide

Introduction to systems

Key Objectives

 Define a system and systems thinking

 Define systems technology

 Read and interpret systems diagrams

 Create and evaluate accuracy of diagrams

 Define sustainability and its three components

 List possible metrics of sustainability and identify opportunities to use  them to assess sustainability of plant and landscape systems Definitions

Reservoir: measure the amount of something in

 Ex: cm, liters, gallons

Flux: the input or output in rates

 Ex: liters/second, drops/minute

Open system: open flow throughout the system; no obstructions Closed system: a system that does not flow openly; has an obstruction or  end

Closed system w/ a feedback loop: similar to a closed system but the  resources are recycled to be used again  


What is Flux?



Balancing (negative) feedback loop: hold a system to an equilibrium state  and make it more stable

Reinforcing (positive) feedback loop: tend to move a system away from  equilibrium and make it more unstable

Sustainability: "Meeting needs of the present without compromising ability of future generations to meet their own needs" -United Nations; a goal and a  spectrum; varies based on resources and differing views

 Systems thinking is essential for addressing societal challenges like  energy, food, climate change, poverty, etc.  

Metrics of sustainability in a landscape system

 Economy

o Job security

o Innovation  

o Capital Investments

 Society

o Quality of life

o Equality

o Well-being

 Environment

o Biodiversity

o Climate change

o Efficient resource use

Introduction to Horticultural Plant and Landscape Systems


What is Sustainability?



Key Objectives

 Define Agronomy and Horticulture; know differences and similarities  Know different divisions of Horticulture

 Discuss Horticultural systems in Nebraska and their relationship to  broader systems Don't forget about the age old question of what is the meaning of adaptation in science?

 List job opportunities in the industry and how they contribute to the  system of jobs in US

Definitions

Horticulture: a combination art, science, business including the production of  fruits, nuts, vegetables, and flowers, and landscape management Agronomy: study of soil management and crop production We also discuss several other topics like luc wille

 Includes Horticulture systems

 Spatial Scale

o Food, fiber, fuel

o Grain

o Forage

o Oil

o Pulse

o Sugar

Olericulture: vegetable production

Vegetable (Botanical definition): vegetative part of the plant Vegetable (Horticultural definition): crops, eaten cooked or raw, as part of the main meal  

Turfgrass Science: Precision, evidence-based management to conserve  resources; golf courses, sporting fields, lawn care

Floriculture: garden/bedding plants, cut and potted flowers Ornamental horticulture: Botanical gardens are often educational and  interactive

Landscape Architecture and environmental horticulture (nurseries): fill urban  landscapes

Arboriculture: care and study of urban area treesWe also discuss several other topics like eng 1460 u of m

 Gardens can be multi-acre farms or in backyards

Art

 Floral design

 Landscape design/architecture  

Science

 Breeding new cultivars of flowers and edible crops

 Pest management  If you want to learn more check out clemson rosetta stone

o Pesticide development

 Nutrient management

o Fertilizer amount research

 Post-harvest physiology

o Storage temp, packing conditions

Business

 Job market opportunities

o Research and development

o Entrepreneurship

o Marketing, sales, distribution

o Education and extension  

o Landscape and golf course design  

o Greenhouse, nursery, farms, golf courses

Seven Divisions of Horticulture

1. Pomology: Fruit and nut cultivation

2. Olericulture: Vegetable Cultivation

3. Turfgrass: Care of grasses on lawns, sporting fields, and golf courses 4. Floriculture: Care of garden, bedding, cut and potted flowers  5. Ornamental: Botanical gardens, conservation

6. Arboriculture: Care of urban trees  

7. Landscape Architecture: Urban landscapes, nurseries  

 Locally grown produce is about quality and relationships

 In 1893 the Supreme Court decided that tomatoes were a vegetable for tax purposes

 Definitions vary based on tradition and location

Members of the Brassicaceae family include:

 Cabbage Don't forget about the age old question of Caregiver in room with child, how does the child interact with them?
We also discuss several other topics like openstax tutor

 Broccoli

 Brussels sprouts

 Radishes

 Kale

 Cauliflower

Members of the Cucurbitaceae family include:

 Cucumbers

 Melons

o Watermelon

o Pumpkins  

 Turfgrass Science uses tools to calculate water usage and storage to  become more sustainable

 Ornamental Horticulture is often used to preserve and conserve  genetics of rare species to avoid extinction

 Landscapes are designed for aesthetics and ecology

 Arborists provide tree removal, pruning, and training services

Horticulture system values extend beyond plant and landscape systems  Health system

 Housing system  

 Job market
