N-P-K
N-P-K is an acronym for these 3 essential plant nutrients.
What is Nitrogen, Phosphorus, and Potassium?
Soil texture only refers to these 3 particles.
What is sand, silt, and clay?
What is the rhizosphere?
This soil order is most ideal for farming.
What are mollisols?
An ideal soil for farming has this % of OM.
What is 5%?
This is one sign of Nitrogen (N) deficiency in plants.
What is yellowing of older leaves?
This soil particle has the most surface area due to its microscopic size.
What is clay?
This fungi forms a symbiotic relationship with plant roots, and helps plants efficiently obtain nutrients.
What is mycorrhizae?
This soil order is found in dry, desert regions.
What are aridisols?
All living (or once living) organisms contain this element.
What is carbon (C)?
This is the role of potassium (K) in plants.
What is stress tolerance?
This soil particle is the largest in size, but has the least amount of surface area.
What is sand?
Mushroom fungi are essential for the breakdown of this type of plant tissue.
What is woody tissues?
This soil order is commonly found in wetlands.
What are histosols?
This is OM in an advanced decomposition state.
What is humus?
This is the role of phosphorus (P) in plants.
What is maturation?(ex. flowering, fruiting, seed development)
This type of soil is a blend of sand, silt, and clay particles. (Though not always in equal proportions)
What is loam?
This is the ideal temperature range for microbial activity.
What is 68oF - 100oF?
This soil order is known for its shrink-swell characteristics.
What are vertisols?
This practice creates partially stabilized, useful organic decay products outside of the soil.
What is composting?
This plant family is known for its ability to provide biological N to soils.
This soil is approximately 40% sand and 20% clay.
What is loam?
This soil organism can cause damage by piercing plant roots and leaving wounds exposed to pests.
What are parasitic nematodes?
This soil order is the "youngest" or least developed. It is usually found in floodplains.
What are entisols?
What are grass clippings, hay, wood chips, manure, plant food scraps, pine needles, etc?
