Abstract	Adoption of no-till (NT) is low in the Lower and Middle Brazos River Watershed of Texas, leaving soil vulnerable to erosion, exacerbating flooding, and contributing to high nutrient and sediment levels in surface waters. To investigate the impact of NT on soil structure and hydraulic function in the region, we measured saturated hydraulic conductivity, organic carbon, bulk density, slaking index of soil aggregates (inversely related to aggregate stability), and soil structure in farm fields under three management systems: conventional tillage (CT), NT, and perennial grass (PG). Soil structure was measured using a novel method for 3D scanning of soil surface horizons – multistripe laser triangulation. Slaking index was measured using a recently developed smartphone application. Exploratory factor analysis combined with a semi-supervised cluster analysis showed that, in general, CT and PG fields were classified into different clusters from one another. Three fields managed with NT for 21, 21, and 7 years were classified in the same cluster as PG fields, while the remaining fields (managed with NT for 21, 21, 18, and 3 years) were classified with CT fields. Organic carbon was significantly higher in NT compared to CT fields. Conventional fields had significantly lower hydraulic conductivity than PG fields and hydraulic conductivity was 1.3 cm h⁻¹ higher in NT than CT fields. Soil structure measured from 10–30 cm depth was significantly improved in NT compared to CT. Improvements in organic carbon and soil hydraulic function are meaningful indicators of improved physical soil health that can be used to promote NT adoption. Improvements in organic carbon and soil hydraulic function also provide ecosystem services to off-site stakeholders who are impacted by erosion and sedimentation resulting from soil tillage. The two novel measurements (a metric derived from scanning of soil structure and slaking index from a smartphone application) were particularly sensitive to management system.

Abstract	The concept of soil health is appropriately receiving increased attention from governments, producers, corporations, and other stakeholders because of the many functions of soil that support ecosystem services and farm profitability. With this interest, there is growing need to verify and monitor changes in soil health that result from how agricultural soil is managed. There are many indicators of soil health and, although this benefits the scientific community, it complicates interpretation across studies. The North American Project to Evaluate Soil Health Measurements (NAPESHM) assessed over 30 available measurements on 124 long-term agricultural research sites with replicated soil health treatments and created new pedotransfer functions. This analysis draws on findings from NAPESHM to identify a minimum suite of effective indicators of soil health for the North American Continent. The criteria for a minimum suite of effective indicators are that they (1) primarily reflect soil health rather than inherent soil properties or fertility, (2) are responsive to agricultural management practices that exemplify soil health principles, (3) are conducive to measuring soil health at scale in terms of cost and availability, and (4) are not redundant with regard to linking different soil functions to ecosystem services. Many indicators were determined effective for use in soil health studies and based on this analysis, soil organic C concentration, aggregate stability, and 24 h C mineralization potential were selected for the minimum suite of indicators. Using this minimum suite, as few as three laboratory measurements can be made to assess and track improvement in soil functioning as a result of soil management changes. These indicators may be supplemented with new pedotransfer functions to also estimate changes in available water holding capacity. This minimal suite of soil health measurements is recommended for scaling up soil health assessments across North America, and possibly beyond.

Abstract	Plants remove carbon dioxide from the atmosphere through photosynthesis. Because agriculture's productivity is based on this process, a combination of technologies to reduce emissions and enhance soil carbon storage can allow this sector to achieve net negative emissions while maintaining high productivity. Unfortunately, current row-crop agricultural practice generates about 5% of greenhouse gas emissions in the United States and European Union. To reduce these emissions, significant effort has been focused on changing farm management practices to maximize soil carbon. In contrast, the potential to reduce emissions has largely been neglected. Through a combination of innovations in digital agriculture, crop and microbial genetics, and electrification, we estimate that a 71% (1,744 kg CO

Abstract	An in situ penetrometer system that can measure profile soil properties rapidly, cost-effectively, and at high vertical resolution would benefit the soil science and agriculture communities. A visible and near infrared (VisNIR) integrated multi-sensing penetrometer system was developed to automatically measure in situ soil VisNIR reflectance spectra, penetration resistance, and insertion depth along a soil profile. The system was tested in 11 agricultural fields in Nebraska, Illinois, Iowa, and South Dakota of the U.S. An independent soil VisNIR spectral library was used to build calibration models for soil property prediction. External Parameter Orthogonalization (EPO) was used to correct for the field intactness of in situ VisNIR spectra. The results showed that EPO was effective in correcting for the spectral disparity between in situ and dry-ground VisNIR spectra. The EPO correction showed an improvement of prediction accuracy of soil total carbon (R2 and RMSE improved from 0.29 and 3.06 % to 0.5 and 0.79 %, respectively) and total nitrogen (R2 and RMSE improved from 0.51 and 0.36 % to 0.62 and 0.06 %, respectively). The system also predicted soil bulk density with an RMSE of 0.12 g cm−3 and R2 of 0.80. It is concluded that the VisNIR multi-sensing penetrometer, along with the use of external soil spectral libraries and the spectral correction algorithm EPO, can lead to a rapid, robust and cost-effective system for in situ high resolution vertical soil sensing.

Abstract	Visible and near‐infrared reflectance spectroscopy (VisNIR, 350–2500 nm) is a proximal sensing technique for rapid and nondestructive soil analysis in the laboratory or field. It can be used to estimate multiple soil properties simultaneously and is usually cheaper than conventional soil analysis methods. In addition to many soil constituents (such as clay minerals, organic matter, water, and carbonates) with which VisNIR light energy directly interacts, this method can also estimate soil properties that are related to these directly measured properties, such as cation exchange capacity (CEC), pH, and salinity. Samples are usually air dried, ground, and sieved (passing 2‐mm screens) before being scanned by a VisNIR instrument. Multivariate statistical modeling techniques (such as partial least squares regression) are commonly used to build VisNIR models from a training set. The VisNIR models estimate target soil properties from VisNIR data. The performance of the VisNIR model needs to be objectively evaluated with an independent test set. Visible and near‐infrared reflectance spectroscopy has been mainly used in the research domain, with a lot of ongoing efforts to further develop and refine this method for routine soil analysis.

Abstract	The measurement of aggregate stability is widely used for establishing quantified soil condition ratings. These ratings can inform managers and scientists on effective soil management practices and identify regions where poor soil conditions are jeopardizing the environment and soil productivity. However, many current methods for quantifying soil conditions are complicated and time‐consuming, and require specialized equipment, especially the measure of aggregate stability. SLAKES is a smartphone application created by the University of Sydney, Australia, that quantifies aggregate stability through a simple experiment. The experiment requires three pea‐sized soil peds, a petri dish of water, and a smartphone running the SLAKES application. The application takes 10 min to produce an on‐screen measurement of aggregate stability and a downloadable text file of the ped dissolution over time. SLAKES, along with the Cornell Wet Aggregate Stability Test, was used on seven conventional tillage, seven no‐till, and eight perennial grass fields to determine whether the application showed sensitivity to different management practices. All 22 sites were on Vertisols (Typic Haplusterts). The SLAKES results showed higher significant separation of means (p < .0001) between each management type than the Cornell method, which was only able to differentiate between conventional tillage and perennial grass management at a lower significance (p = .06). SLAKES proved to be a legitimate method for quantifying aggregate stability based on slaking. With this simplified aggregate stability measurement method, rating and quantifying soil health is viable for anyone with a portable electronic device and is much less tedious than traditional lab‐based methods.

Abstract	The focus of this paper is the relationship between soil health and global food security. We discuss the role of climate change on food security and the role of farmer profitability in promoting soil health. Specific objectives were to (a) consider the role that U.S. agricultural production plays in global food security, (b) consider key mechanisms by which soil health impacts U.S. agricultural production, and (c) offer a comprehensive strategy to scale adoption of soil health systems. Based on the Food and Agriculture Organization's (FAO) Food Price Index, U.S. commodity exports influence global food prices, linking U.S. crop production to food security. Soil health affects food security through crop yield, crop yield resilience, and farmer profitability. Results relating soil health and crop yield are complicated by biophysical complexity, lack of standardized research practices, and the scale of research trials. Studies of the relationship between yield resilience and soil health are similarly inconclusive. Despite mixed research results, interviews with 100 U.S. farmers found over half reported increased crop yield due to soil health management systems, and most reported more resilient yields. Partial budget analysis of production information from 100 interviews found using soil health management systems increased net farm income (in 2020 U.S. dollars) by US$127.61 ha–¹ ($51.66 acre–¹) for maize (Zea mays L.) and $110.84 ha–¹ ($44.87 acre–¹) for soybean [Glycine max (L.) Merr.]. We detail a path to increase adoption of soil health systems so healthy soils can serve as the foundation for producing food, mitigating climate change, and increasing farmer profitability.
