Autoclaved-citrate extractable soil protein (ACE protein, hereafter referred as "soil protein") is a novel biological health indicator that can indirectly capture soil's capacity to supply nitrogen (N) but relatively expensive assess. To explore cost saving options, dataset of 4,171 samples with texture, total carbon (C) and N, carbon-to-nitrogen ratio (C/N), permanganate-oxidizable (POXC), pH, magnesium (Mg) iron (Fe), was used develop three pedotransfer functions for protein. These included full random forest (RF) model utilizing all variables, reduced RF multiple linear regression employing subset the variables. Models were validated using US North American Project Evaluate Soil Health Measurements contained 1,406 samples. The root mean square error (RMSE) by 41.7 53.4% compared models, respectively. Total C more important variable in than N. Additionally, POXC, sand, clay, Mg Fe found be model. sensitive management at 36 57 long-term experiments. able replicate 92% those significant effects on new function improve prediction traditional techniques reduce comprehensive assessment.

Abstract Greater awareness of the role soil management in achieving global production goals and mitigating emerging environmental challenges has focused spotlight on health assessment interpretation. The site‐specific characteristics long been recognized through small‐scale experimental studies, protocol evaluation (SHAPE) tool was developed to facilitate cross‐site comparisons provide regionally relevant interpretation by accounting for factors. Specifically, SHAPE version 1.0 account primary climate‐edaphic factors including long‐term climate means (temperature precipitation) edaphic (soil texture suborder). Version 1.0S further incorporates a spatially explicit, heteroskedastic approach into Bayesian linear regression model refine peer‐group scoring curves benchmark values based proximity. This captures regional variability improves relevance interpretability scores values.

Soil health is an important concept in promoting sustainable agriculture and food security, yet the absence of universally accepted benchmarks limits its utility assessing soil function. This study explored use Conservation Reserve Program (CRP) soils as a potential benchmark to quantify gap (SHG) Faribault County, Minnesota. Using Management Assessment Framework (SMAF), we evaluated physical, chemical, biological, nutrient indicators derive combined overall score that was used SHG (i.e., minus test soil) between CRP corn-based agricultural production (AP). Three paired farms were assessed, each consisting tall grass prairie established 2001 adjacent long-term AP. The results showed higher SMAF scores soils, with mean 0.09. Land had strong influence on scores, largely driven by biological such organic carbon, microbial biomass β-glucosidase activity. However, demonstrated limited applicability systems, potentially under-representing their status due SMAF’s emphasis lack ecosystem-specific factors pH.

Abstract Soil health assessments aim to quantify soil status using indicators linked ecosystem services such as yield, nutrient cycling, water or carbon storage. Many are related biological processes, which can be challenging interpret because they sensitive not only management, but also nonmanagement variables inherent properties, topography, and climate. Existing studies address this challenge by grouping similar soils taxonomy, geography, a combination of these other for assessment. We investigated whether based on multiple quantitative topsoil properties could an alternative taxonomic geographic groups. used unsupervised classification algorithm, k ‐means, cluster publicly available climate data Minnesota. Clustering into eight conceptual groups (“clusters”) 10 was determined the optimal algorithm output. evaluated ability our clusters methods explain variance in indicators. found Major Land Resource Area (MLRA) performed best, explaining much more than groupings five The distinguish zones variation at field scale, MLRAs account broader scale landscape factors. approach we describe is flexible applied different locations scales produce associated maps support test sampling interpretation scale.

Abstract Aggregate stability is a critical physical indicator of soil health. However, multiple methods are used for measuring aggregate stability, making it difficult to compare results and limiting universal interpretations in health assessment frameworks like Soil Health Assessment Protocol Evaluation. We cross‐correlated three common water‐stable (WSA CASH , WSA ARS SLAKES ) using dataset nearly 1400 samples developed pedotransfer functions random forest models evaluate method performance. found that the can be reasonably cross correlated through because they use similar processes estimating strength. Conversely, not transferable. suggest most established best reference analysis frameworks. Interpretation consistency will lead more robust comparisons as key indicator.
