Soil Bulk Density Estimation Methods: A Review

Pedosphere, 2018
Abstract 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.

Computing bulk density of swelling soils

Soil Technology, 1989
Summary 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.

Synthesizing Bulk Density for Soils with Abundant Rock Fragments

Soil Science Society of America Journal, 1994
Abstract Bulk density is a fundamental soil property that is difficult to determine for gravelly to extremely gravelly soils because results vary significantly with sample volume. For such coarse soils, the representative volume (for whole‐soil bulk density) should be large, but guidelines for selecting an appropriate sample volume do

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 ...

Developing pedotransfer functions for predicting soil bulk density in Campania

Geoderma, 2022
Oven-dry soil bulk density (BD) is a key soil parameter in biophysical models. Yet, its direct determination for large-scale modeling applications is limited by excessive efforts required for labor-demanding, time-consuming, expensive field campaigns and laboratory-based measurements.

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).

Measurement of Soil Bulk Density and Moisture

Transactions of the ASAE, 1987
ABSTRACT BULK density and moisture content of soil influence the soil conditions created by tillage, vehicle trafficability, soil compaction caused by vehicles, water infiltration and drainage, and crop growth. Measurement and description of soil conditions are necessary for correct management decisions to create soil conditions that will maximize ...

Influence of Soil Bulk Density on Matric Potential

Soil Science Society of America Journal, 1962
Abstract Unsaturated soil samples were compressed at three different moisture contents and temperatures to evaluate these interrelations with soil moisture matric potential. It was found that in all cases increasing bulk density, at constant moisture content and temperature, resulted in an increase in soil moisture matric potential ...

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.
