Soil bulk density is a good indicator of problems of root penetration, soil aeration, and water infiltration. Knowledge of soil water content is important to understand crop water use, leaching of chemicals, and soil trafficability. The purpose of this presentation is to detail, step by step, how to measure soil bulk density and how to successfully use newer soil moisture sensors. Soil bulk density measurement is needed to convert soil properties from a mass to a volume basis, and is a useful indicator of soil compaction. Soil water content affects the level of soil compaction which is indicated by its bulk density. Numerous soil moisture sensors have been introduced, but often require site-specific calibration. Various methods are discussed, illustrated, and compared.
