Flashcards in Soil/Plant Nutrition Cont'd Deck (23):
This is a complex mixture of particles, composed of inorganic and organic constituents.
This is an aggregate of two or more minerals.
This process releases mineral nutrients and creates a substance more amenable for life.
Heat, ice and pressure are factors of what type of weathering.
This type of weathering creates smaller particles and releases nutrients into soil.
This type of weathering is a result of of a variety of organisms aiding in soil production.
This soil is soft in consistency and fosters tooth growth.
This horizon of soil is considered to be "top soil", it is made up of humus and broken down rocks.
This horizon of soil is made up of less organic matter and is mostly rock.
This horizon of soil is made up of partially broken down rock.
What are the 3 major soil particles?
This is the dissolution and removal of inorganic ions as water moved through soil.
This process is the replacement of mineral cations by H+ ions.
This is a symbiotic relationship in which both participants benefit.
This is a narrow region of soil that is directly influenced by root secretions and associated soil microorganisms.
These form mutualistic relationships with roots and play a major role in plant nutrition.
These are the mutualistic associations of roots and fungi.
This type of mycorrhizae grow on the root surface.
This type of mycorrhizae grow into the root cortex.
These are specialized structures for nutrient transfer.
These grow attached to other plants but NOT SOIL and are NOT PARASITES.
These grow attached to other plants and obtain their source of nutrients from the host.
