Misc. Soil
This soil fraction causes soils to be dark brown or black in color.
What is organic matter (OM)?
Wetlands typically have this type of soil order.
What are histosols?
Humid/Tropical regions typically have this type of soil pH.
What is acidic?
This soil order is the most ideal for farming.
What are mollisols?
This type of tillage uses heavy machinery and results in soil compaction over time.
What is conventional tillage?
This fungi acts as an extension of plant roots, aiding in nutrient uptake.
What is mycorrhizae?
These types of plants are usually found in wetlands.
What are hydrophytes or hydrophilic plants?
The presence of these ions is responsible for soil acidity.
What are H+ or hydrogen ions?
This soil order is commonly found in dry, desert regions.
These are crops grown during the off season, primarily to improve soil health and slow erosion.
What are cover crops?
These are the 5 soil forming factors.
1. Parent Material
2. Climate
3. Living Organisms
4. Topography
5. Time
?
These are 2 benefits of wetlands.
What is
Species habitat
Water filtration
Flood reduction
Shoreline protection
Recreational Activities
Natural Products
Scenic Beauty
?
Soil pH can be raised by this slow process.
What is liming?
This soil order is known for its shrink-swell characteristics.
What are vertisols?
Planting marigolds in between vegetable crops is one example of this type of planting method.
What is companion planting?
Water moves in this direction in response to capillary movement/action.
What is all directions?
These types of wetlands may be created to treat wastewater in urban areas.
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 soil order is the "youngest" or least developed. Usually found in floodplains.
What are entisols?
This type of tillage leaves at least 30% of crop residues on the soil surface after harvest.
What is conservation tillage?
This is how plants respond to water stress.
What is closing stomata and cease transpiration?
This is one reason why wetlands are drained.
What is farming
engineering/construction
?
This is how plant roots obtain nutrients from the soil.
What is cation exchange? (Plant roots exchange H+ ions for nutrients)
This soil order is found in acidic forest regions, for example the Mvskoke homelands.
What are spodosols?
This is how new fields were traditionally prepared by Mvskoke men.
What is trees were girdled and their slow death and decomposition fertilized the soil?
