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.

Soil Technology, 1990
Abstract We offer comment on a recent paper by SHARMA which provides an empirical analysis of clod bulk density calculations in swelling soils. We provide an alternative theoretical analysis which is less data demanding yet capable of giving considerable insight into other soil physical process such as compaction.

Synthesizing Bulk Density for Soils with Abundant Rock Fragments
Soil Science Society of America Journal, 1994Abstract 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

Measurement of Soil Bulk Density and Moisture
Transactions of the ASAE, 1987ABSTRACT 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 ...

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 ...

Influence of Soil Bulk Density on Matric Potential
Soil Science Society of America Journal, 1962Abstract 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 ...
