Environmental Initiatives I Flashcards
What is the challenging relationship that exists between agriculture and the environment?
ITs exists because agriculture co exists with the environment and depends on limited natural resources like soil water and wildlife to produce food
What can using resources do to the environment?
Degrade quality and result in environmental issues
What are environmental initiatives?
To improves their practices and reduce negative impacts on the environment
Who can adopt environmental initiates and why?
Individual or business
-they do thrive because they are stewards of the land and they manage the land and directly depend on its health for their livelihood
What are some things that can degrade resources?
Human activities like:
-urbanization
-Industry
0Agriculture
What is soil health a reflection of?
The ability of the soil to support living members of the e ecosystem by providing resources and services
Why is soil a non-renewable resource?
Soil building processes are slow
-degraded soil can’t be replenished within the time period of a human lifespan
How does erosion occur?
Because water does not infiltrate the dense soil and instead flows ver the soil surface
Why is erosion bad?
Reduces seed germination and plant cover because the soil crust is difficult to penetrate
What is erosion?
A natural process that breaks down landforms and removes oil nutrients and damages its structures
What are the 3 types of erosion that can occur?
Water
Wind
Tillage
How does water erosion occur?
When the force of water suspends soil nd carries it away
How does wind erosion occur?
When high speed wind disturbs loose soil, commonly on unprotected dry land
How does tillage erosion occur?
Whe tollage loosens the soil on hills and gravity causes the soil to roll down the slopw
What environmental problems can erosion lead to?
Water quality is degraded when soil and nutrients are carried into aquatic environments
Soils are less health because the loss of nutrients and soil structure degrades the life supporting properties of soil
What is organic matter?
Is the top layer of soil that includes decomposing plant and animal matter
What is the purpose of organic matter?
Enhances soil properties like structure, ability to hold nutrients and support of soil organisms that can suppress insects and disease
What environmental problems can occur when you have a lack of organic matter?
Poor soil Structure develops because organic matter is no longer gluing soil particles together to form stable clumps that allow air and water exchange
Loose soil is prone to rearranging densely to form a thick crust that limits water penetration
What is soil compaction?
Pressess soil particles together and reduces the size of the spaces between soil particles.
Why are large spaces necessary for soil?
To allow water to infiltrate and for air exchange
When is soil compaction more likely to occur?
When there is traffic over a field, high soil moisture and heavy equipment
What is the best management strategy for soil?
Rebuilding soil is a slow process so the best management strategy is to protect it
-adopting practices that will enhance and protect soil quality on their farm
What are the 4 main best practice initiatives to manage soil use?
Cover crop and leave plant residue
Growth living windbreaks
Spread Manure
Establish permanent traffic patterns
