Soil Water
An ideal soil contains pore space with this % of water.
What is 25%?
This soil order is the most ideal for farming.
What is a mollisol?
Soils texture only refers to these 3 particles.
What is sand, silt, and clay?
An ideal soil has this % of air filled pore space.
What is 25%?
Alkaline soils are commonly found in this type of climate.
What are deserts, dry, arid, low rainfall climates?
These large soil pores are responsible for rapid water movement in saturated soils, where water movement is influenced by gravitational energy.
What are macropores?
This soil order is commonly found in dry, desert regions.
What are aridisols?
This soil particle has the most surface area due to its microscopic size.
What is clay?
These soil colors indicate poor aeration and reduced oxygen.
What is grey and blue?
The presence of these ions is responsible for soil acidity.
This is where groundwater meets soil.
What is the water table?
This soil order is commonly found in wetlands.
What are histosols?
This type of soil is a blend of sand, silt, and clay particles. (Though not in equal proportions)
What is loam?
These types of plants (ex. pitcher plants) are adapted to anaerobic or poor airflow soil conditions.
What are hydrophytes or hydrophytic plants?
Most plant nutrients are available within this pH range.
What is 5.5 to 6.5?
When water reaches the soil surface, it meets a fork in the road, where it can make one of these 2 choices.
What is infiltrate or become surface runoff?
This soil order is known for its shrink-swell characteristics.
What are vertisols?
This soil is approximately 10% sand and 70% silt.
What is a silt loam?
Subsurface soil temperatures are warmer then surfaces soil temperatures during this time of year.
What is winter?
These types of soils are characterized by their extremely high sodium (Na) content which results in poor water infiltration, low osmotic potential, and hard white layers in the soil surface.
What are sodic soils?
This energy force is responsible for slow water movement in micropores and relies mostly on cohesion and adhesion for water movement.
What is matric energy?
This soil order is the "youngest" or least developed. Usually found in floodplains.
What are entisols?
This soil is 65% sand and 30% clay.
What is a sandy clay loam?
This physical process cools soil surfaces.
What is evaporation?
This element becomes extremely soluble at low pH and can reach toxic levels for plants in acidic soils, resulting in nutrient deficiencies and stunted root growth.
What is aluminum (Al)?
