PLS 2 Chapter #4 Soil Texture Quizizz

What does soil texture refer to?

• The organic matter content in the soil

• The proportion of sand, silt, and clay particles

• The pH level of the soil

• The color of the soil

Which type of soil is high in sand relative to clay?

• Loam soil

• Clay soil

• Heavy soil

• Light soil

Why is soil texture important?

• It affects the soil's temperature

• It influences water holding capacity, water movement, and soil fertility

• It determines the soil's pH level

• It determines the soil's color

Which soil type is well aerated but does not hold much water?

• Sand

• Clay

• Silt

• Loam

What is a characteristic of clay soils?

• High water holding capacity

• Low nutrient supply

• Low susceptibility to compaction

• High infiltration rate

What is a uniform soil profile?

• Same texture throughout the soil profile

• Texture decreases with depth

• Abrupt texture change between topsoil and subsoil

• Texture gradually increases down the soil profile

How do you determine soil texture using the ribbon method?

• By observing the soil's color

• By measuring the soil's pH

• By weighing the soil sample

• By forming a flat ribbon with wetted soil and measuring its length

What is the length of the ribbon for sandy soil?

• <15 mm

• 15–25 mm

• 25 mm

• 40–50 mm

Which soil type has a moderate to high plant available water and is moderately to highly susceptible to mechanical compaction?

• Sandy loam

• Loam

• Clay loam

• Clay

What is the characteristic of heavy clay soil?

• High susceptibility to mechanical compaction

• Low plant available water

• Root growth not restricted

• High infiltration rate
