part 1
What is soil texture?
Soil texture (such as loam, sandy loam or clay) refers to the proportion of sand, silt and clay sized particles that make up the mineral fraction of the soil.
what is
A type of soil that is made up of large particles
What is the difference between light and heavy soils? Light soils are high in sand?
light soil refers to a soil high in sand relative to clay, while heavy soils are made up largely of clay.
Define-
Decomposition
Decomposition or rot is the process by which dead organic substances are broken down into simpler organic or inorganic matter such as carbon dioxide, water, simple sugars and mineral salts.
What do earthworms do in soil?
feed primarily on organic material in soils, eating fresh and decaying material from plant roots, including crops like corn and soybeans
What are the three layers form the soil profile?
Most soils have three major horizons -- the surface horizon (A), the subsoil (B), and the substratum (C).
what is
Even mixture of sand, silt , and clay with moderate water
Define soil structure
the way individual particles of sand, silt, and clay are assembled.
Define-
Biological properties
The ability of a biomaterial to perform its desired function with an appropriate host response in a specific application
What is CEC?
Cation exchange capacity
What is a common reason why soil maps are used?
They are commonly used for various purposes, including agricultural planning, land management, and environmental assessments.
what is
A type of soil made up of large particles of sand and the pore spaces allow for aeration .
What is the structure of platy soil?
The units are flat and plate-like
Define-
Pore formation
We define pore-forming proteins as proteins that are initially produced.
How is soil PH measured?
using both water and calcium chloride.
What is soil erosion?
Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate.
How much water can your soil hold?
Soil can hold 400-600 water per meter of soil dept
What is the structure of Prismatic soil
The individual units are bounded by flat or slightly rounded vertical faces.
What do plants absorb in carbon recycling?
carbon dioxide
What is Soil PH
an indication of the acidity or alkalinity of soil
What is organic matter?
large source of carbon-based compounds found within natural and engineered, terrestrial, and aquatic environments.
How does a 'sandy' soil feel like to touch?
feels gritty
eparates almost entirely into discrete units that are loosely packed, roughly spherical, and mostly between 1 and 2 mm in diameter
What do Microorganisms do?
contribute to digestion, produce vitamin K, promote development of the immune system, and detoxify harmful chemicals
What is organic matter
Organic matter, organic material, or natural organic matter refers to the large source of carbon-based compounds found within natural and engineered, terrestrial, and aquatic environments.
