Determination of bulk density of soil clod by saturation

Geoderma, 1971
Abstract A method for the bulk density determination on soil clod is described. Clods are oven-dried, weighed and equilibrated over water saturated sand columns. Total volume of the clod is computed from the volume of its components - solid, and air. Air volume is calculated from the increase in weight of the dry clod on saturation.

Use of Soil Cores in Determining Bulk Density

Soil Science Society of America Journal, 1971
Abstract 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, 1964
In 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, 1998
Soil 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 ...

Organic Matter as a Measure of Bulk Density of Soil

Nature, 1966
THE 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.

Bulk Density of Soils in Relation to Soil Physical and Chemical Properties

Soil Science Society of America Journal, 1991
Abstract 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

BULK DENSITY EQUATIONS FOR SOUTHERN ALASKA SOILS

Canadian Journal of Soil Science, 1989
A close relationship between organic-carbon content and bulk density was utilized to develop equations for predicting the bulk densities of inorganic soils around the Gulf of Alaska; for example[Formula: see text]where Db is the bulk density (Mg m−3) of fine-earth and OC is the organic carbon content (g kg−1).
