Computing bulk density of swelling soils
Soil Technology, 1989Summary A procedure for computing bulk density of a soil with swelling clays at any moisture content between saturation and shrinkage limit is presented. The method is simple and involves only one sampling at any field moisture content above the soil's shrinkage limit.

Grassland management effects on soil bulk density
Transactions of the Kansas Academy of Science, 2004Abstract Various grassland management regimes have been and are being utilized in northeastern Kansas, all of which could impact soil properties. Differences in one such property, soil bulk density, could indicate differences in soil quality. Five regimes of privately managed grasslands (cool-season: hay or grazed, warm season: hay, grazed or ...

Bulk Density Sampler for Deep Soil Profiles
Soil Science Society of America Journal, 1975Abstract A bulk density sampler, adapted from a conventional commercial type, was constructed and used to obtain soil samples at more than 50 sampling sites from depths to 30 m. This sampler increased the speed with which samples were taken because it was readily added to or detached from the drilling unit between sequences of ...

Soil Bulk Density Estimation Methods: A Review
Pedosphere, 2018Abstract Measurement of soil bulk density is important for understanding the physical, chemical, and biological properties of soil. Accurate and rapid soil bulk density measurement techniques play a significant role in agricultural experimental research.

Use of Soil Cores in Determining Bulk Density
Soil Science Society of America Journal, 1971Abstract The bulk density of soil samples obtained with a hydraulic soil coring machine, for both core segments and clods, was compared to the bulk density of soil samples obtained with a Uhland sampler and natural clods taken from a soil pit. Subsurface, upper B, and lower B horizon samples were compared.

A STUDY OF BULK DENSITY AND WATER IN A SWELLING SOIL
Soil Science, 1964In this examination of the character of the contraction of an undistrubed field soil, models for three-dimensional and undimensional contraction were set up from which changes in bulk density with moisture content could be predicted and the predictions compared with measured values.

SOIL BULK DENSITY ESTIMATION FOR TILLAGE SYSTEMS AND SOIL TEXTURES
Transactions of the ASAE, 1998Soil bulk density ( .b) is a physical property related to many phenomena, such as plant root development and solute transport in soils. In this study, a comprehensive data search of literature from 1980 to 1997 was made to examine .b as influenced by soil organic matter (OM), soil texture, primary tillage and secondary tillage practices and tillage ...

Bulk Density of Soils in Relation to Soil Physical and Chemical Properties
Soil Science Society of America Journal, 1991Abstract Soil scientists and engineers commonly require bulk density ( D b ) data as parameter input of simulation models predicting a wide range of soil processes. Field methods exist to measure D b

Organic Matter as a Measure of Bulk Density of Soil
Nature, 1966THE compactness of a soil is known to be related to its content of water and air, and to the temperature and the supply of nutrients1,2. Although a rough estimate of compactness is sometimes obtained with penetrometers, bulk density provides a more correct overall picture of the physical conditions of a soil.
