Combined sensor of dielectric constant and visible and near infrared spectroscopy to measure soil compaction using artificial neural networks [PDF]
, 2014 Soil compaction is a widely spread problem in agricultural soils that has negative agronomic and environmental impacts. The former may lead to poor crop growth and yield, whereas the latter may lead to poor hydraulic properties of soils, and high risk to

Advanced Materials, EarlyView.Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics
Advanced Materials, EarlyView.“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Near infrared spectroscopy for soil bulk density assessment
, 2009 P>Soil bulk density values are needed to convert organic carbon content to mass of organic carbon per unit area. However, field sampling and measurement of soil bulk density are labour-intensive, costly and tedious. Near-infrared reflectance spectroscopy

Ratiometric Mycotoxin Detection in Living Plants With Dual‐Emissive Nanosensors
Advanced Materials, EarlyView.A minimally invasive microneedle patch integrates carbon dot‐embedded metal–organic frameworks as nanosensors to detect a key fungal toxin in living plants. The nanosensor produces a ratiometric fluorescence signal that enables early, non‐destructive diagnosis of fungal infection before visible symptoms, offering a new biomaterials‐based strategy for ...

The effects of tyre systems on the depth and severity of compaction [PDF]
, 2006 High value crops such as peas for the frozen vegetable market have to be harvested at the optimum point for quality, regardless of field conditions. Six wheeled pea harvesters with a gross weight of 27 t, giving a wheel load of 4.5 t are required to move

, 2022 Processes responsible for natural recovery of compacted forest soils are poorly understood, making estimating their recovery problematic. Bulk density was measured over 7 years at nine boreal forest sites in Alberta, Canada, where harvest-only and three ...

Influence of Carbon Nanoparticles on Electrically Induced Wear of Grease‐Lubricated Steels
Advanced Materials Interfaces, EarlyView.When an electric current enters a pair of rubbing surfaces, enormous damage takes place. In this research, how such damage occurs in the presence of protective grease and the mitigation with added carbon nanoparticles, were investigated. It was discovered that those particles regulate transport and interfacial electrical stability of the grease ...

Influence of bulk density on soil resistance and yield of tobacco
, 2011 Influence of soil compaction on the growth and development of flue-cured tobacco was investigated at the experimental station of the Tobacco institute Zagreb. Research was carried out in model trials, in Mitscherlich's pots. Three soil compaction levels (1.2, 1.4 and 1.6 gcm-3) were randomized according to the block method with four replications.

Predicting soil bulk density for incomplete databases
Geoderma, 2014 Abstract Soil bulk density (ρb) is important because of its direct effect on soil properties (e.g., porosity, soil moisture availability) and crop yield. Additionally, ρb measurements are needed to express soil organic carbon (SOC) and other nutrient stocks on an area basis (kg ha− 1).
