The study explores the partial root zone drying method, an irrigation strategy aimed at improving water use efficiency. We imaged the root–soil interaction using non-destructive techniques consisting of soil and plant current stimulation. The study found that imaging the processes in time was effective in identifying spatial patterns associated with irrigation and root water uptake. The results will be useful for developing more efficient root detection methods in natural soil conditions.

Reversal polarity is observed in rock glacier seismic refraction tomography. We collected several datasets observing this phenomenon in Switzerland and Italy. This phase change may be linked to interferences due to the presence of a thin low-velocity layer. Our results are confirmed by the modelling and analysis of synthetic seismograms to demonstrate that the presence of a low-velocity layer produces a polarity reversal on the seismic gather.

Soil compaction resulting from inappropriate agricultural practices affects soil ecological functions, decreasing the water-use efficiency of plants. Recent developments contributed to innovative sensing approaches aimed at safeguarding soil health. Here, we explored how the most used geophysical methods detect soil compaction. Results, validated with traditional characterization methods, show the pros & cons of both non-invasive techniques and their ability to characterize compacted areas.

Our paper concerns the use of a dense network of low-cost seismic accelerometers in populated areas to achieve rapid and reliable estimation of exposure maps in Trentino (northeast Italy). These additional data, in conjunction with the automatic monitoring procedure, allow us to obtain dense measurements which only rely on actual recorded data, avoiding the use of ground motion prediction equations. This leads to a more reliable picture of the actual ground shaking.

Pseudo-relict rock glaciers look visually relict but contain patches of permafrost. They are poorly known in terms of permafrost content, spatial distribution and frequency. Here we use spring-water temperature for a preliminary estimate of the permafrost presence in the rock glaciers of a 795 km2 catchment in the Italian Alps. The results show that ~50 % of rock glaciers classified as relict might be pseudo-relict and might contain ~30 % of the ice stored in the rock glaciers in the study area.

Bentonite buffer surrounding the waste canister is a critical part of the multi-barrier system for high-level radioactive waste geological repositories that undergo heating from heat-emitting waste and hydration from the host rock. Thus, extensive research was conducted to study the alteration of bentonite due to heating and hydration under high temperatures (200 °C); this work provides valuable data for model validation.

In the last decades, geochemical investigations at the springs of rock glaciers have been used to estimate their drainage processes, and the frozen layer is typically considered to act as an aquiclude or aquitard. In this work, we evaluated the hydraulic behavior of a mountain permafrost site by executing a geophysical monitoring experiment. Several hundred liters of salt water have been injected into the subsurface, and geoelectrical measurements have been performed to define the water flow.

A new combination of temperature, water pressure and cross-borehole electrical resistivity data is used to investigate ice/water contents in an ice-rich rock glacier. The landform is close to 0°C and has locally heterogeneous characteristics, ice/water contents and temperatures. The techniques presented continuously monitor temporal and spatial phase changes to a depth of 12 m and provide the basis for a better understanding of accelerating rock glacier movements and future water availability.

The Ice Memory project aims to extract, analyze, and store ice cores from worldwide retreating glaciers. One of the selected sites is the last remaining ice body in the Apennines, the Calderone Glacier. To assess the most suitable drilling position, geophysical surveys were performed. Reliable ground penetrating radar measurements have been positively combined with a geophysical technique rarely applied in glacier environments, the Frequency Domain Electro-Magnetic prospection.

This study presents the development and validation of a novel acquisition system for measuring finely resolved depth profiles of soil and snow temperature at multiple locations. Results indicate that the system reliably captures the dynamics in snow thickness, as well as soil freezing and thawing depth, enabling advances in understanding the intensity and timing in surface processes and their impact on subsurface thermohydrological regimes.

This paper has developed a tractable approach for characterizing watershed heterogeneity and its relationship with key functions such as ecosystem sensitivity to droughts and nitrogen export. We have applied clustering methods to classify hillslopes into
watershed zonesthat have distinct distributions of bedrock-to-canopy properties as well as key functions. This is a powerful approach for guiding watershed experiments and sampling as well as informing hydrological and biogeochemical models.

The novel hybrid predictive modeling (HPM) approach uses a long short-term memory recurrent neural network to estimate evapotranspiration (ET) and ecosystem respiration (Reco) with only meteorological and remote-sensing inputs. We developed four use cases to demonstrate the applicability of HPM. The results indicate HPM is capable of providing ET and Reco estimations in challenging mountainous systems and enhances our understanding of watershed dynamics at sparsely monitored watersheds.

We develop a hybrid model to estimate the spatial distribution of the thickness of the soil layer, which also provides estimations of soil transport and soil production rates. We apply this model to two examples of hillslopes in the East River watershed in Colorado and validate the model. The results show that the north-facing (NF) hillslope has a deeper soil layer than the south-facing (SF) hillslope and that the hybrid model provides better accuracy than a machine-learning model.

We propose a new strategy called distributed temperature profiling (DTP) for improving the estimation of soil thermal properties through the use of an unprecedented number of laterally and vertically distributed temperature measurements. We tested a DTP system prototype by moving it sequentially across a discontinuous permafrost environment. The DTP enabled high-resolution identification of near-surface permafrost location and covariability with topography, vegetation, and soil properties.

Soil organics carbon (SOC) and its influence on terrestrial ecosystem feedbacks to global warming in permafrost regions are particularly important for the prediction of future climate variation. Our study proposes a new surface–subsurface, joint deterministic–stochastic hydrological–thermal–geophysical inversion approach and documents the benefit of including multiple types of data to estimate the vertical profile of SOC content and its influence on hydrological–thermal dynamics.

Snow has a profound impact on permafrost and ecosystem functioning in the Arctic tundra. This paper aims to characterize the variability of end-of-winter snow depth and its relationship to topography in ice-wedge polygon tundra of Arctic Alaska. In addition, we develop a Bayesian geostatistical method to integrate multiscale observational platforms (a snow probe, ground penetrating radar, unmanned aerial system and airborne lidar) for estimating snow depth in high resolution over a large area.

Quantifying water and heat fluxes in the shallow subsurface is particularly important due to their strong control on recharge, evaporation and biogeochemical processes. This study developed and tested a new inversion scheme to estimate subsurface hydro-thermal parameters by joint using different hydrological, thermal and geophysical data. It is especially useful for the increasing number of studies that are taking advantage of autonomously collected measurements to explore ecosystem dynamics.

The paper presents an integrated approach to monitoring root water uptake and link this information to the plant transpiration measured by sap flow and eddy covariance. The monitoring of soil conditions is achieved using 3-D electrical resistivity tomography. This ensemble of data can be used jointly to model the soil-plant interactions and identify the extent and efficiency of the root zone in front of existing irrigation schemes. A case study is presented regarding an orange orchard in Sicily.

This study focuses on the potential of catch crops as monocultures or mixtures to improve the soil water management and reduction of soil N leaching losses. All catch crop treatments preserved soil water for the main crop and their potential can be optimized by selecting suitable species and mixture compositions. Mixtures can compensate for the individual weaknesses of monocultures in N cycling by minimizing leaching losses and maximizing the N transfer to the main crop.

Unravelling relationships between plant rhizosheath, root exudation and soil C dynamic may bring interesting perspectives in breeding for sustainable agriculture. Using four pearl millet lines with contrasting rhizosheaths, we found that δ13C and F14C of root-adhering soil differed from those of bulk and control soil, indicating C exudation in the rhizosphere. This C exudation varied according to the genotype, and conceptual modelling performed with data showed a genotypic effect on the RPE.

Since the 20th century, human beings have released a large amount of reactive nitrogen by excessive application of nitrogen fertilizer, which resulted in enhanced greenhouse effect. It is not clear how the ecosystem nitrogen cycle evolves during global warming. In this study, we collected global data and used meta-analysis to reveal the response of nitrogen cycle to climate warming. The results show that the future climate warming can accelerate the process of ecosystem nitrogen cycle.

The central Mongolian forest steppe underlies a recent decline of forested area. We analysed the site and soil properties in the Khangai Mountains to identify differences between disturbed forest areas with and without regrowth of trees. More silty soils were found under areas with tree regrowth and more sandy soils under areas without tree regrowth. Due to the continental, semi-arid climate, soil properties which increase the amount of available water are decisive for tree regrowth in Mongolia.

tree against hunger, enset (Ensete ventricosum) is an important multipurpose crop for the farming systems of the densely populated Gamo highlands in Ethiopia. Its high productivity and tolerance to droughts are major assets. Nevertheless, enset production is severely threatened by a wilting disease. This observational study aims to assess soil and leaf nutrients in enset gardens at different altitudes to see if fertility management can be linked to disease prevalence.

Long-term studies on the impact of land use change and crop selection on soil organic carbon (SOC) stocks in sub-Saharan Africa are scarce. Accordingly, this study analysed the impact of converting natural grasslands to a range of low-input production systems in a tropical savannah on SOC stocks. Apart from the cultivation of legume tree and/or shrub species, all land management techniques were detrimental. Grazed grasslands in particular had almost 50 % less SOC than natural grasslands.

Phosphorus (P) seems to be a limiting factor for forest nutrition. At many German forest sites, trees show a deficiency in P nutrition. However, total soil P is an inadequate predictor to explain this malnutrition. We examined if soil properties such as pH, SOC, and soil texture may be used to predict certain P pools in large forest soil inventories. Models using soil properties and P pools with different bioavailability are not yet adequate to explain the P nutrition status in tree foliage.

We investigated how the composition of bone char (BC) particles altered in soil and affected the soil P speciation by fractionation and X-ray absorption near-edge structure spectroscopy. Bone char particles (BC from pyrolysis of bone chips and BCplus, a BC enriched with S compounds) were collected at the end of incubation-leaching and ryegrass cultivation trials.

For this study we systematically investigated the molecular pattern of leaf waxes in litter and topsoils along a European transect to assess their potential for palaeoenvironmental reconstruction. Our results show that leaf wax patterns depend on the type of vegetation. The vegetation signal is not only found in the litter; it can also be preserved to some degree in the topsoil.

Investigation of a Dutch sandy profile demonstrated that buried soils provide beneficial growth conditions for plant roots in terms of nutrients. The intense exploitation of deep parts of the soil profile, including subsoil and soil parent material, by roots of the modern vegetation is often underestimated by traditional approaches. Potential consequences of deep rooting for terrestrial carbon stocks, located to a relevant part in buried soils, remain largely unknown and require further studies.

Zinc (Zn) deficiency is widespread in all types of soils of world including acid soils affecting crop production and nutritional quality of edible plant parts. The present study was carried out to assess the effects of lime and farmyard manure addition to two acid soils of India on soil properties, extractable zinc by different extractants, dry matter yield, Zn concentration and uptake by maize. Increased level of lime application led to enhancement of soil pH and reduction in extractable Zn in

Switchgrass is a deep-rooted perennial grass bioenergy crop that can sequester soil C. Although switchgrass ecotypes vary in root biomass and architecture, little is known about their effect on soil microbial communities throughout the soil profile. By examining labeled root-C uptake in the microbial community, we found that ecotypes supported different microbial communities. The more fungal community associated with the upland ecotype could promote C sequestration by enhancing soil aggregation.

Different tree species affect interrill erosion, but a higher tree species richness does not mitigate soil losses in young subtropical forest stands. Different tree morphologies and tree traits (e.g. crown cover or tree height) have to be considered when assessing erosion in forest ecosystems. If a leaf litter cover is not present, the remaining soil surface cover by stones and biological soil crusts is the most important driver for soil erosion control.

The "local adaptation" component of integrated soil fertility management operates at field and farm scale. At field scale, the application of implements other than improved germplasm, fertilizer, and organic inputs can enhance the agronomic efficiency (AE) of fertilizer. Examples include the application of lime, secondary and micronutrients, water harvesting, and soil tillage practices. At farm scale, targeting fertilizer within variable farms is shown to significantly affect AE of fertilizer.

This paper aims to test a new physically oriented approach to viticulture zoning at the farm scale which is strongly rooted in hydropedology and aims to achieve a better use of environmental features with respect to plant requirement and wine production. The physics of our approach are defined by the use of soil-plant-atmosphere simulation models which apply physically based equations to describe the soil hydrological processes and solve soil-plant water status.

In this study we show how soil water repellency (SWR) is linked to the quantity and quality of SWR markers in soils mainly derived from vegetation. To predict the SWR of topsoils, we find the strongest relationship with ester-bound alcohols, and for subsoils with root-derived ω-hydroxy fatty acids and α,ω-dicarboxylic acids. From this we conclude that, overall, roots influence SWR more strongly than leaves and subsequently SWR markers derived from roots predict SWR better.

Terroir chemical and biological footprinting and geospatial technologies are promising for the management of terroir units, particularly remote and proxy data in conjunction with spatial statistics. In practice, the managed zones will be updatable and the effects of viticultural and/or soil management practices might be easier to control. The prospect of facilitated terroir spatial monitoring makes it possible to address the issue of terroir sustainability.

The available soil water (ASW) is a major contributor to the viticulture "terroir". Electrical resistivity tomography (ERT) allows for measurements of soil water accurately and with low disturbance. This work reviews the use of ERT to spatialise soil water and ASW. A case example is also presented: differences in water uptake (as evaluated by fraction of transpirable soil water variations) depending on grapevine water status (as measured by leaf water potential) are evidenced and mapped.

Since seeds are the principle means by which plants move across the landscape, the final fate of seeds plays a fundamental role in the origin, maintenance, functioning and dynamics of plant communities. In arid and semiarid patchy ecosystems, where seeds are scattered into a heterogeneous environment and intense rainfalls occur, the transport of seeds by runoff to new sites represents an opportunity for seeds to reach more favourable sites for seed germination and seedling survival.

This study covers both aspects of understanding of soil system and soil contamination after 14 years of fertilizer application and residual effects of the fertilization 8 years after cessation of fertilizer treatment. Although many grassland fertilizer experiments have been performed worldwide, information about residual effects of fertilizer applications on grassland ecosystem functioning is still rare. This study reports the importance of monitoring of the long-term impact of fertilization.

Short summary
The use of non-invasive geophysical imaging of root system processes is of increasing interest to study soil–plant interactions. The experiment focused on the behaviour of grapevine plants during a controlled infiltration experiment. The combination of the mise-à-la-masse (MALM) method, a variation of the classical electrical tomography map (ERT), for which the current is transmitted directly into the stem, holds the promise of being able to image root distribution.
