Jul 26, 2024 · Gravimetric soil moisture detection involves collecting a soil sample, weighing the moist soil, drying it in an oven at 105°C for 24-48 hours, re-weighing the dried sample, and calculating the percentage of water lost based on the initial moist sample weight. This method is one way of estimating soil moisture.

Soil moisture detection is the ability to locate and measure subsurface moisture content so we can learn what it has to tell us. There are several methodologies that can be used.
Anywhere soil moisture is detected, something valuable, often essential, can be learned. For example, soil moisture in the vicinity of underground utility pipes can tell us where drinking water is leaking so that repairs can be made. In fact, for the water industry, soil moisture detection (by satellite) is far more efficient than traditional acous...
Detection and analysis of soil moisture can provide vital information with the potential to save lives, water, energy, money, crew resources, and the environment. In the example of leaking utility pipes, water, money, and energy (and the resulting carbon emissions) all must be expended again to replace what was lost. Leaking wastewater pipes can se...
In all of these situations, moisture detection and analysis in soil can help detect any number of threats so that action can be taken to safeguard lives, property, business, and the environment. Please visit ASTERRA’s Solutions Pageto learn about new advances in soil moisture detection using satellites and algorithmic analysis.
Moisture in soil could refer to two different things: water content (the amount or percentage of water in soil) or water potential (the energy state of water in soil). One is an extensive variable, and the other is an intensive variable (learn about these variables here). A search using the term “soil moisture sensor” will turn up both ...
Nowadays, the measurement makes use of sensors, and the calibration has been done by factory calibration for soil moisture sensors that typically gives accuracy of ± 3% for typical soils (Cobos and Chamber 2010), such as in 10HS soil moisture sensor (Spelman et al. 2013; Domínguez-Niño et al. 2019) and SMT100 soil water content sensor (Bogena et al. 2017) so that the users can determine the ...

Most people look at soil moisture only in terms of one variable: soil water content. But two types of variables are required to describe the state of water in the soil: water content, which is the amount of water, and water potential, which is the energy state of the water. Soil water content is an extensive variable. It changes with size and ...
Sep 20, 2022 · Soil Moisture Using Remote Sensing The advantage of remote sensing is that it can gauge moisture over much larger areas than conventional methods. Additionally, satellite technology makes it possible to generate high-resolution soil moisture maps , which allow modeling crop yields in individual areas of the field and improving overall production efficiency.

Aug 4, 2014 · The use of the “plant-available soil water content, PAWC” concept to identify the soil moisture is preferred since it provides a somewhat clearer identification of the soil volume (i.e., the rooting zone) where soil moisture is effective from both the monitoring and modeling purposes. This soil volume is connected to the evapotranspiration processes and can be assumed as the uppermost soil ...
