Multiple Choice

Water Holding Capacity is an important soil property in soil because:

1

It is measure of the portion of water in the soil that is available to plants

2

It is measure of all the water in a soil profile

3

It is measure of water in the soil that is moved down by gravity

4

It is measure of soil water after a heavy rain or full irrigation run

45

Multiple Choice

1

Soils high in sand

2

Soils high in loam

3

Soils high in silt

4

Soils high in clay

1

True

2

False

58

Multiple Choice

Why is soil texture important?

1

It determines how fast water drains through soil

2

It determines how much water a soil can hold and make available to plants

3

Both written responses

4

Neither written responses

Multiple Choice

Loam

1

When rubbed between the thumb and fingers, approximately equal influence of sand, silt and clay is felt. makes a weak ribbon (less than 2.5 cm long)

2

Silt is the dominant particle in silt loam, which feels quite smooth or floury when rubbed between the thumb and fingers. Weak ribbon (less than 2.5 cm)

3

Clay dominates, it is smooth when dry and slick/ sticky when wet. Silt and sand are usually present in noticeable amounts, but are over shadowed by clay. Medium ribbon (2.5 to 5 cm long)

4

Varies from very fine loam to very coarse, Feels quite sandy or gritty, but contains some silt and a small amount of clay. The amount of silt and clay is sufficient to hold the soil together when moist. Weak ribbon (less than 2.5 cm long)

5

Noticeable amounts of both silt and clay are present Makes a medium ribbon (2.5 to 5 cm long)
