“…Most of the commercially available CE systems like [149], [150] are targeted towards bio-molecule detection costing $1000s and are limited to lab setting. However, recent advances have been made in the development of economical field-applicable CE systems for nutrient/inorganic ion monitoring in soil samples [151], [152].…”

Development and deployment of sensing technologies is one of the main steps in achieving sustainability in crop production through precision agriculture. Key sensing methodologies developed for monitoring soil moisture and nutrients with recent advances in the sensing devices reported in literature using those techniques are overviewed in this article. The soil moisture determination has been divided into four main sections describing soil moisture measurement metrics and laboratory-based testing, followed by in-situ, remote and proximal sensing techniques. The application, advantages and limitations for each of the mentioned technologies are discussed. The nutrient monitoring methods are reviewed beginning with laboratory-based methods, ion-selective membrane based sensors, bio-sensors, spectroscopy-based methods, and capillary electrophoresis-based systems for inorganic ion detection. Attention has been given to the core principle of detection while reporting recent sensors developed using the mentioned concepts. The latest works reported on the different sensing methodologies point towards the trend of developing low-cost, easy to use, field-deployable or portable sensing systems aimed towards improving technology adoption in crop production leading to efficient site-specific soil and crop management which in turn will bring us closer to reaching sustainability in the practice of agriculture.

“…Increased frequency of analyte measurement enabled by automated sensors can be coupled with HTS‐enabled gene expression to identify active taxa. Several innovative sensing technologies have recently been used for nitrate quantification in soil: microfluidics coupled with electrophoretic microchips that do not require soil solution extraction (Xu et al, 2017); Fourier transform infrared spectroscopy (Rogovska et al, 2019); and laser‐induced graphene electrodes capable of recovering more than 95% of nitrate and ammonium added to soil slurries (Garland et al, 2018). Although studies describing these three sensing technologies used point measurements, these sensors could be used with microfluidics adapted for continuous or semi‐continuous monitoring of multiple N species.…”

Roughly half of all nitrogen (N) added to soils is not incorporated by crops and is lost to the environment, but our ability to reduce N loss from soils is hampered by an inadequate grasp of microbial processes affecting N retention and mobility. High-throughput sequencing (HTS) of microbial DNA is enabling fundamental insights into N cycling microorganisms and their metabolisms. This commentary describes six emerging technologies that could be combined with HTS to enable real-time collection of metadata on N transformations, intermediates, and products to link soil properties, microbial processes, and the fate of N. These technologies include microdialysis and microfluidics, automated sensing, microfabrication of model soils, parallel quantification of N functional genes, sorting active cells, and stable isotope probing. Use of integrated technologies applied initially under controlled conditions at small scales can lead to identification of soil conditions and field-scale management practices that promote better N conservation and delivery to agricultural crops.

“…Methodologies enabling early and accurate detection of plant stress due to pathogens and pests provide a way for optimal deployment of countermeasures for reducing of losses in yield. Our group has been pursuing agriculture sensor design for soil [5][6][7][8][9][10][11][12][13][14][15][16][17] and plant health [18][19][20][21][22][23][24][25][26], modeling for soil moisture/nutrients and plant growth dynamics [27,28], and decision-making for irrigation and fertilization for over a decade [27,29].…”

Reducing agricultural losses is an effective way to sustainably increase agricultural output efficiency to meet our present and future needs for food, fiber, fodder, and fuel. Our ever-improving understanding of the ways in which plants respond to stress, biotic and abiotic, has led to the development of innovative sensing technologies for detecting crop stresses/stressors and deploying efficient measures. This article aims to present the current state of the methodologies applied in the field of agriculture towards the detection of biotic stress in crops. Key sensing methodologies for plant pathogen (or phytopathogen), as well as herbivorous insects/pests are presented, where the working principles are described, and key recent works discussed. The detection methods overviewed for phytopathogen-related stress identification include nucleic acid-based methods, immunological methods, imaging-based techniques, spectroscopic methods, phytohormone biosensing methods, monitoring methods for plant volatiles, and active remote sensing technologies. Whereas the pest-related sensing techniques include machine-vision-based methods, pest acoustic-emission sensors, and volatile organic compound-based stress monitoring methods. Additionally, Comparisons have been made between different sensing techniques as well as recently reported works, where the strengths and limitations are identified. Finally, the prospective future directions for monitoring biotic stress in crops are discussed.
