“…In that respect, ground-penetrating radar (GPR) and electromagnetic induction (EMI) are non-invasive geophysical techniques which can be used to characterize the shallow subsurface properties at the field scale with high temporal and spatial resolutions (André et al, 2012;Cockx et al, 2007;Huisman et al, 2003;Jonard et al, 2011;Lambot et al, 2008;Slob et al, 2010). EMI is sensitive to soil electrical conductivity, which is mainly affected by soil water content (SWC), clay content, and salinity (Corwin and Lesch, 2005;Friedman, 2005), while GPR is sensitive to both soil electrical conductivity and dielectric permittivity, the latter primarily depending on SWC (Topp et al, 1980).…”

Tillage practices influence physical, chemical, and biological soil properties, which also affect soil quality and consequently plant growth. In this study, the main objective was to evaluate the effects of different tillage practices on soil physical properties such as soil water content (SWC) by using geophysical methods, namely, ground-penetrating radar (GPR) and electromagnetic induction (EMI). Additional measurements such as soil sampling, capacitance probe, and soil penetrometer data were acquired as ground truths. The study was performed for three contrasting tillage practices, i.e., conventional tillage (CT), deep loosening tillage (DL), and reduced tillage (RT), applied on different plots of an agricultural field. The data showed that tillage influences soil resistance in shallow soil layers (deeper tillage decreases soil resistance), which could be partly seen in on-ground GPR data. In addition, reference SWC measurements (capacitance probes and soil sampling) were in fairly good agreement with the water content estimates from off-ground GPR. We also observed a tillage effect on shallow surface SWC, while deeper SWC seems to be unaffected by tillage. Mean surface SWC was significantly lower for CT compared to DL and RT, which was partly explained by lower pore connectivity between the topsoil and the deeper layers after conventional tillage. Moreover, the variance of the SWC within the conventional tillage plots was larger than within the other plots. This larger SWC variability could be explained by a greater soil heterogeneity induced by the plowing process. Overall, this study confirms the potential of GPR and EMI for the determination of soil physical properties at the field scale and for the assessment of agricultural management practices.

“…Pioneering research by Bramley and Hamilton (2004) and Bramley (2005) not only highlighted the magnitude and extent of the spatial variability of yield in some Australian vineyards (of between 4.5 and 7.3 ha) but also emphasized the significant influence of soils in driving yield differences. The need to assess spatial variations in soil properties has driven the development and application of direct (so-called "proximal") geophysical sensing, particularly for measuring soil apparent electrical conductivity by means of either electrical resistivity surveys and/or electro-magnetic induction scans (EMI) (Lamb et al, 2005;Morari et al, 2009;Taylor et al, 2009;Trought and Bramley, 2011;Fulton et al, 2011;André et al, 2012;Martini et al, 2013; al., 2013; Priori et al, 2013a, b;Rossi et al, 2013;Brillante et al, 2014). Moreover, the need to assess spatial variation in grapevine biomass and canopy properties, or to map terroir units or to identify vines, has driven the development, acquisition and processing of remote-sensing data.…”

“…Sensing results are often limited to qualitative information and geophysical sensing results are ambiguous, making reliable quantification of sensing information still a major challenge (Werban et al, 2013). Indeed, geophysical surveys have mainly resulted in delineating within-field zones (Lamb et al, 2005;Taylor et al, 2009;Costantini et al, 2010;André et al, 2012;Martini et al, 2013;Priori et al, 2013a, b), rather than predicting soil properties, such as clay content (Rodríguez-Pérez et al, 2011;Andrenelli et al, 2013), extractable Na + and Mg 2+ contents (Rodríguez-Pérez et al, 2011), or soil moisture (Brillante et al, 2014). Apparent electrical conductivity (ECa) values are "affected by various soil properties in a complex manner and it is difficult to discriminate the weight that each soil parameter has on the final apparent measured ECa" (Martini et al, 2013) so that the Pearson's correlation coefficient is often not significantly high between ECa and soil parameters such as clay content or gravimetric water content.…”

Abstract. Notions of terroir and their conceptualization through agro-environmental sciences have become popular in many parts of world. Originally developed for wine, terroir now encompasses many other crops including fruits, vegetables, cheese, olive oil, coffee, cacao and other crops, linking the uniqueness and quality of both beverages and foods to the environment where they are produced, giving the consumer a sense of place. Climate, geology, geomorphology and soil are the main environmental factors which make up the terroir effect on different scales. Often considered immutable culturally, the natural components of terroir are actually a set of processes, which together create a delicate equilibrium and regulation of its effect on products in both space and time. Due to both a greater need to better understand regional-to-site variations in crop production and the growth in spatial analytic technologies, the study of terroir has shifted from a largely descriptive regional science to a more applied, technical research field. Furthermore, the explosion of spatial data availability and sensing technologies has made the within-field scale of study more valuable to the individual grower. The result has been greater adoption of these technologies but also issues associated with both the spatial and temporal scales required for practical applications, as well as the relevant approaches for data synthesis. Moreover, as soil microbial communities are known to be of vital importance for terrestrial processes by driving the major soil geochemical cycles and supporting healthy plant growth, an intensive investigation of the microbial organization and their function is also required. Our objective is to present an overview of existing data and modelling approaches for terroir functional modelling, footprinting and zoning on local and regional scales. This review will focus on two main areas of recent terroir research: (1) using new tools to unravel the biogeochemical cycles of both macro-and micronutrients, the biological and chemical signatures of terroirs (i.e. the metagenomic approach and regional fingerprinting); (2) terroir zoning on different scales: mapping terroirs and using remoteand proxy-sensing technologies to monitor soil quality and manage the crop system for better food quality.

“…Several research reports have shown that resistivity could be used to map permanent soil properties at farm scale (André et al 2012;Buvat et al 2014). In some cases, soil texture can dominate the resistivity pattern overshadowing soil structure and water-related properties (Banton et al 1997).…”

The sustainable management of human activities, from production to waste disposal and the cycling of finite resources, is one of the great challenges of research for the coming decades, stemming from societal needs and the growing awareness of environmental mechanisms.Research on geophysical methods provides an interdisciplinary approach to such challenges by addressing the need for techniques to assist in designing and monitoring strategies for sustainability in agriculture and other environment-related sciences.In the past few decades, technological advances have produced new tools or have improved existing techniques for near-surface geophysical investigation in a robust, cost-effective, and noninvasive way. Experimental results have proved that soil physical properties thus detected and mapped can be used as a proxy of physical, chemical, and biological features relevant for the appropriate management of soils, based on their behavior, spatial variability, and time dynamics.This chapter reviews principles of the techniques and reports selected research results on environmental and agronomic research.
