How is bulk density calculated?
By dividing the dry weight of soil by its volume
By multiplying the dry weight of soil by its volume
By adding the dry weight of soil to its volume
By subtracting the dry weight of soil from its volume
What effect does cultivation have on bulk density?
Increases bulk density
Decreases bulk density
Has no effect on bulk density
Only affects bulk density in sandy soils
What does bulk density reflect about the soil?
Soil color
Soil's ability to function for structural support, water and solute movement, and soil aeration
Soil temperature
Soil pH level
What is one of the uses of bulk density measurements?
To determine soil color
To express soil physical, chemical, and biological measurements
To measure soil temperature
To calculate soil pH
What can high bulk density lead to in terms of soil erosion?
Reduced soil erosion
Increased soil erosion
No effect on soil erosion
Only affects soil erosion in sandy soils
What is the effect of freeze/thaw cycles on soil bulk density?
Significantly increases bulk density
Significantly decreases bulk density
Has very little effect on bulk density
Only affects bulk density in clay soils
What is the effect of soil depth on bulk density?
Decreases bulk density
Increases bulk density
Has no effect on bulk density
Only affects bulk density in sandy soils
Which soil texture has an ideal bulk density for plant growth of less than 1.40 g/cm³?
Sandy

Which conservation practice results in bulk density favorable to soil function?
Consistently plowing to the same depth
Using heavy equipment for building site preparation
Cover crop
Allowing equipment traffic on wet soil
What is one long-term solution to bulk density and soil compaction problems on cropland?
Consistently plowing to the same depth
Using heavy equipment for building site preparation
Using cover crops, crop residues, perennial sod, and/or reduced tillage
Allowing equipment traffic on wet soil
