True
False
List the soil particles in order from largest to smallest grain size: sand, clay, gravel & silt
(a)
Sand will feel smooth and sticky when conducting a soil texture test
True
False
Clay soils have good permeability compared to sandy soils
True
False
Place the soil Textures in order from best to worst regarding soil permeability characteristics: gravel, clay, silt, sand
(a)
What is soil structure?
structure refers to how quickly water filters through the soil
structure refers to the size of the particles in the soil
structure is a measurement of the ability for soil to hold water
structure refers to the arrangement of soil
How do organic matter and minerals affect the water holding capacity of a soil?
mineral matter acts like a sponge to hold water in the soil
organic matter add parent material to profile
organic matter acts like a sponge to hold water in the soil
organic matter allows water to drink quickly from the soil
organic matter adds to soil porosity
True
False
Organic matter can consist of which of the following substances?
Rock particles
decaying plant parts
soil minerals
Water
Temperature and rainfall influence the amount of organic matter found in the soil
True
False
In soil, an increase in the number of pores will reduce soil permeability
True
False
Which soil type provides for the best soil permeability?
Sandy
solid bedrock
Clay
silt
Why is soil permeability important for plant growth?
it prevents water from entering the root Zone
that fertilizes the plant through osmosis
it allows water to filter through the soil preventing flooding
