Tests on Effect of Gravity and Soil Density on Soil Cone Index
Advanced Materials Research, 2013The cone index is one of the important indicators that can describe the comprehensive physical characteristics of lunar regolith. Its closely related to the sink and sideslip of lunar rover and also has widely used in prediction the trafficability, adhesion property, tractive performance of lunar rover.

Soil electromagnetic parameters as functions of frequency, soil density, and soil moisture
Proceedings of the IEEE, 1974Measurements are made to determine the conductivity and dielectric constants of a gray clay loam and a reddish-brown clay loam. The measurements are made as a function of soil density (from 1.2 g/cm3to 1.8 g/cm3), soil moisture (from 0 percent to 20 percent of the dry soil weight), and excitation frequency (from 30 MHz to 4 GHz), using standard ...

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 Densities of California Soils in Relation to Other Soil Properties
Soil Science Society of America Journal, 1980Abstract Analyses of 721 samples from inorganic horizons of upland and alluvial soils in seven orders were utilized to develop equations for predicting soil bulk density at 1/3‐bar water content. The minimum standard errors of estimate (0.14 g cm −3 , r

[Impact of Biochar on Soil Bulk Density and Aggregates of Lou Soil].
Huan jing ke xue= Huanjing kexue, 2019The effect of biochar on the bulk density and aggregate stability of Lou soil was evaluated and compared after biochar was applied for 2 years and 5 years through a field-positioning experiment. Five biochar amounts were applied in this study, as follows:0 t·hm-2 (B0), 20 t·hm-2 (B20), 40 t·hm-2 (B40), 60 t·hm-2 (B60), and 80 t·hm-2 (B80).

Determination and Use of Soil Bulk Density in Relation to Soil Compaction
1994Summary Bulk density and some related terms which quantify soil compactness are defined and discussed. Methods for measuring bulk density are considered in two groups. Direct methods involve the measurement of sample mass and volume, while indirect methods are based on the effect of soil on nuclear radiation.
