Abstract: The soil complex dielectric permittivity (CDP) is a fundamental physical quantity utilized in microwave remote sensing to estimate soil moisture. Although several four-parameter (soil ...

Smart farming use cases, particularly battery-powered and in remote locations, require low-power devices and secure wireless ...

This study assessed a novel passive L-band UAS-mounted sensor to map near-surface soil moisture in a natural landscape using three flights conducted over 1 year to capture seasonal changes in soil ...

Because we do not have spatially continuous moisture measurements, we divide the profile into discrete depths around the soil moisture sensors in each soil layer as described by the following equation ...

Sensors are designed to provide a soil profile, gleaning information about organic matter, moisture and acidity. The technology also has potential for an artificial intelligence application ...

Suprem Das, an associate professor in K-State’s Department of Industrial and Manufacturing Systems Engineering, said advancing soil sensors ... farmers could adjust water, nitrogen and ...

At a global scale, this process — called transpiration — is a key component of the terrestrial water cycle. When soil is moist enough, transpiration is controlled by net radiation. By contrast ...
