Biodegradable Wireless Soil Urea Sensor Using Metamaterial Perfect Absorber for Distributed Deployment in Precision Agriculture

open access: yesAdvanced 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.

THE EFFECTS OF GYTTJA ON SOIL PROPERTIES IN NICKELCONTAMINATED SOILS

open access: yesApplied Ecology and Environmental Research, 2019
In this study, the effects of gyttja on some soil properties in two different nickel-contaminated soils (Inceptisol and Entisol) were investigated. This study was conducted with the application of three levels of gyttja (0, 5 and 10%) in two different soils (Inceptisol and Entisol) contaminated with Ni at three levels of concentration (0, 40 and 80 mg ...

Mechanical properties of tree roots for soil reinforcement models

open access: yes, 2001
Evidence from forestry has shown that part of the forest floor bearing capacity is delivered by tree roots. The beneficial effect however varies and diminishes with increasing number of vehicle passes. Roots potential for reinforcing the soil is known to

The optimization of going management on UK racecourses using controlled water applications [PDF]

open access: yes, 2006
Non-uniform surface rating (going) on a racecourse increases the potential for risk of injury to competing horses and their riders. Variability in soil type and strength are the primary cause of inconsistent going.

Echinoderm‐Inspired Autonomy for Soft‐Legged Robots

open access: yesAdvanced Robotics Research, EarlyView.
Inspired by echinoderms, a modular soft robot achieves autonomous phototaxis without a central controller or explicit communication. Each limb independently adapts its actuation timing through local sensing and short‐term memory. Coordination emerges purely from physical interactions, demonstrating resilience to changes in morphology, environment, and ...
