THE EFFECTS OF WATER CONTENT VARIATION ON ADHESION FACTOR OF PILE FOUNDATION IN EXPANSIVE SOIL [PDF]
, 2013 Seasonal change causes variations in soil moisture content. On expansive soil, this condition influences soil moisture content in the active zone, which is approximately in five meters depth.

Monitoring the Soil Water Content Using Time Domain Reflectometry in a Clay Loam and an Organic Soil
Journal of Agricultural Sciences, 2002 n the present study, Time Domain Reflectometry TDR and tensiometers were used to follow changes in soil water content and soil water pressure head over time in soil containers filled with a clay loam soil and an organic soil.

Advanced Materials Technologies, EarlyView.This paper presents an agar medium with a phosphorescent grid pattern that measures the stress distribution generated by growing plant roots. Using phosphorescence, the system optically separates the grid pattern from the root and extracts the grid deformation.

How shallow and how many points of measurements are sufficient to estimate the deep profile mean soil water content of a hillslope in the Loess Plateau? [PDF]
, 2018 Soil water content (SWC) measurements for deep soil profiles involve large and expensive expenditures of time and labor. However, understanding of soil water dynamics for deep soil profiles is very important for soil and water resource management and ...

The critical soil water content and its relation to soil water dynamics [PDF]
Scientia Agricola, 1997 Using an edaphic model that describes the extraction of soil water by plant roots, the occurrence of depletion zones dose to plant roots is demonstrated. These depletion zones affect the root water potential that is needed to maintain a certain transpiration rate.

Advanced Materials Technologies, EarlyView.In this study, we propose a biodegradable wireless soil urea sensor for precision agriculture. The sensor's electromagnetic response varies depending on the urea concentration, allowing the measurement of relative soil urea concentrations by analyzing the time‐transient electromagnetic response.

Conformable Ferrimagnetic Tattoo Electrodes for Plant Electrophysiology
Advanced Materials Technologies, EarlyView.The newly developed ferrimagnetic tattoo electrode is capable of measuring plant electrophysiological activity outside the Faraday cage. Its ability to adhere without damaging the plant tissue allows long‐term recordings. This premise opens new avenues for in‐field monitoring of plant health through electrophysiology.

Fusion of multi soil data for the delineation of management zones for variable rate irrigation [PDF]
, 2013 Up until now, there have been no multi-sensor approaches used to estimate available water content (AWC) in order to determine variable rate irrigation. This has been a major problem for growers adopting precision farming technologies.
