Phase-based soil moisture sensing using radars and passive backscatter tags
Soil moisture sensing is important to optimize water usage in agriculture and fire prevention. In agriculture, it enables smart irrigation systems to use water efficiently, reduce wastage, and enhance crop yields. For fire prevention, accurate soil moisture data improves estimates of fuel moisture …

Nondestructive investigation of soil moisture level using optical system
Soils are one of the essential resources consisting of unconsolidated mineral or organic material on the surface of the Earth; it plays an important role in the growth of land plants. Soil testing is an effort to assess the soil constituents and moisture level; this information is useful to …

High-resolution soil moisture mapping by a proximal ground penetrating radar: A numerical, laboratory and field evaluation
Soil moisture is an important state variable acting in many environmental, hydrologic and climatic processes. There is thus a pressing scientific demand for revealing the soil moisture dynamics in the biosphere at various temporal and spatial scales. Despite the huge development of remote sensing …

Application of thermocouple psychrometers to field measurements of soil moisture potential.
… thermocouple psychrometer has made possible the measurement of soil moisture potentials to values as low as -80 bars. The applicability of this type of psychrometer to "in situ" measurements of moisture potential at a Sonoran desert field site is investigated. An evaluation is made of the effect …

Cosmic-ray neutron sensing for soil moisture measurements in cropped fields
… sensing (CRS) approach to measure field-scale soil moisture in cropped fields. Primary cosmic rays penetrate the top atmosphere and interact with atmospheric particles. Such interaction results on a cascade of high-energy neutrons, which continue traveling through the atmospheric column. …

Evaluation of the laboratory resilient modulus test using a New Mexico subgrade soil
… of resilient modulus for an A-6 subgrade soil at varying moisture conditions (± 2-3% relative to optimum). Specimens of 2.8 inch and 4 inch diameters are reconstituted using modified proctor compaction. Resilient modulus values are determined using internal and external deformation …
