Abstract The North American Project to Evaluate Soil Health Measurements was initiated with the objective identify widely applicable soil health measurements for evaluation of agricultural management practices intended improve health. More than 20 indicators were chosen assessment across 120 long‐term research sites spanning from north‐central Canada southern Mexico. being evaluated include common standard measures soil, but also newer techniques visible and near‐infrared reflectance...
Soil organic carbon (SOC) is closely tied to soil health. However, additional biological indicators may also provide insight about C dynamics and microbial activity. We used SOC the other (potential mineralization, permanganate oxidizable C, water extractable β-glucosidase enzyme activity) from North American Project Evaluate Health Measurements examine continental-scale drivers of these indicators, relationships among effects health practices on indicator values. All had greater values at...
Aggregate stability is a commonly used indicator of soil health because improvements in aggregate are related to reduced erodibility and improved soil–water dynamics. During the past 80 90 years, numerous methods have been developed assess stability. Limited comparisons among resulted varied magnitudes response management practices influences inherent properties climate. It not clear whether selection specific method creates any advantage investigator. This study assessed four measuring...
Abstract Currently accepted pedotransfer functions show negligible effect of management‐induced changes to soil organic carbon (SOC) on plant available water holding capacity (θ AWHC ), while some studies the ability substantially increase θ through management. The Soil Health Institute's North America Project Evaluate Measurements measured content at field using intact cores across 124 long‐term research sites that contained increases in SOC as a result management treatments such reduced...
Phospholipid fatty acid analysis (PLFA) provides an easy to use and robust measure of changing soil microbial condition. The method data on both the quantity composition community- critical knowledge because community is important component health. However, it challenging for new researchers know how process data, interpret results, its effectiveness in evaluating health management. We set out address these challenges using North American Project Evaluate Soil Health Measurements PLFA...
Abstract Farmers, scientists, and other soil health stakeholders require interpretable indicators of hydraulic function. Determining which to use has been difficult because measurement disconformity, spatial temporal variability, recently established treatments, the effect site characteristics on management practice differences. The North American Project Evaluate Soil Health Measurements includes 124 sites uniformly sampled across a range practices in America 2019. We compare recommend...
Potential carbon mineralization (Cmin) is a commonly used indicator of soil health, with greater Cmin values interpreted as healthier soil. While are typically in agricultural soils managed minimal physical disturbance, the mechanisms driving increases remain poorly understood. This study assessed bacterial and archaeal community structure potential microbial drivers maintained under various degrees disturbance. mineralization, 16S rRNA sequences, characterization data were collected part...
Core Ideas An ESRI Story Map (a web application based on maps) was developed and tested for teaching topography. Student evaluations of the were positive. Maps can be an effective learning tool. Environmental Systems Research Institute (ESRI) are applications maps other multimedia, which effectively used in soil science education. The purpose this study to develop “Soil Forming Factors: Topography” introductory courses assess performance newly story map using ESRI's “five principles...
Abstract Various soil health indicators that measure a chemically defined fraction of nitrogen (N) or process related to N cycling have been proposed quantify the potential supply crops, key function. We evaluated five (total N, autoclavable citrate extractable water‐extractable organic potentially mineralizable and ‐acetyl‐β‐ D ‐glucosaminidase activity) at 124 sites with long‐term experiments across North America evaluating variety managements. found 59%–81% variation in was among sites,...
Abstract Spatial and temporal changes in land cover have direct impacts on the hydrological cycle stream quality. Techniques for accurately efficiently mapping these are evolving quickly, it is important to evaluate how useful techniques address environmental impact of riparian buffer areas. The objectives this study were to: (1) determine classes distribution areas streams; (2) examine discrepancies within existing data from National Land Cover Database (NLCD) using high-resolution imagery...
The performance of seven sediment transport equations for bedload is compared using almost 2,600 more than 8,000 measurements from a recent compilation. Named tested include the Meyer-Peter Muller, Barry, Pagosa good condition, Wilcock, Parker (both calibrated and uncalibrated), Recking, that Elhakeem Imran. purpose tests was to evaluate several empirical semiempirical formulae single calibration point relative three uncalibrated equations. were included because they either have procedure...
Sensor technology can be a reliable and inexpensive means of gathering soils data for soil health assessment at the farm scale. This study demonstrates use color system readings from Nix ProTM sensor (Nix Ltd., Hamilton, ON, Canada) to predict organic carbon (SOC) as well total nitrogen (TN) in variable, glacial till 147 ha Cornell University Willsboro Research Farm, located Upstate New York, USA. Regression analysis was conducted using natural log SOC (lnSOC) TN (lnTN) dependent variables,...
National Atmospheric Deposition Program (NADP) databases are important for quantifying and mapping the contribution of atmospheric deposition to soil provisioning ecosystem services. These provide information about potassium (K+) which is an essential element component many fertilizing materials. flows (wet, dry, total) serve as one input K+ soils; however, varies spatially across United States (U.S.). This study ranked estimated value services due within contiguous U.S. by state region...
Conversion of native grasslands to agricultural sites has resulted in remarkable changes soil carbon at depth, but its impact on diagnostic horizons is unknown. This study was conducted radiocarbon date the organic (SOC) and quantify pedogenic carbonates Russian Chernozem depth three sites: a grassland field (not cultivated for least 300 years), an adjacent 50-year continuous fallow V.V. Alekhin Central-Chernozem Biosphere State Reserve Kursk region Russia (UNESCO—MAB Reserve), cropland...
Atmospheric resources are very important for assessing ecosystem services at different administrative levels (e.g., state, region, etc.). Quantification of atmospheric calcium (Ca2+) deposition on the total basis provides incomplete information about flows (both “natural” and “human-derived”), therefore lacking a systems approach to guide sustainable management which support many services. This study assessed value wet, dry, in contiguous United States (U.S.) by spatial aggregation region)...
The infiltration rate (IR) of water is a key soil property related to hydrological processes, health, and ecosystem services. However, detailed measurements IR in the field and/or laboratory are labor-intensive expensive perform. Soil judging provides rapid inexpensive method estimate classes based on texture, organic carbon/matter, structure. objectives this study were classify compare texture for A horizon across 147 ha Cornell University Willsboro Research Farm using Survey Geographic...
Ecosystem services (ES) often rely on biogeochemical cycles, but values associated with abiotic are ignored or underestimated. from atmospheric magnesium (Mg2+) deposition flows (wet, dry, and total), which can be considered a source of naturally-occurring fertilizer liming material, have not been included in economic valuations ecosystem services. Market-based valuation these service partially address this negative externality. This study assessed the value wet, total contiguous United...
Lithospheric-derived resources such as soil texture and coarse fragments are key physical properties that contribute to ecosystem services (ES), which can be valued based on "soil" or "mineral" stocks. Soil survey data provides an inexpensive alternative detailed field measurements often labor-intensive, time-consuming, costly obtain. However, both contain heterogeneous information with a certain level of variability uncertainty in data. This study compares the potential using from Survey...
