“…The SOM acts as a negatively charge site which attracts cations, resulting in a strong correlation between CEC and SOM. Others (Grigera et al, 2006;Veum et al, 2021) showed that EC was also related to SOM. Soil pH and Al concentration, relating negatively to each other, had limited associations with soil biological and biochemical properties.…”

“…The chemical reactions among nutrients, contaminants, toxic elements, soil organic matter (SOM), and composition of soil solution affect soil, water, air, and food quality (Ohno and Hettiarichchi, 2018). Soil chemical properties are mostly used to measure soil fertility and health compared to physical and biological properties due to their rapid measurement, applicability to field conditions, accessible to producers, dynamic nature, and ability to capture a wide range of soil functions (Brejda et al, 2000;Veum et al, 2021). Differences in inherent characteristics of soils can result in variations in soil health that influence crop yields and environmental quality (Veum et al, 2021).…”

“…Chemical soil health indicators used for nutrient availability to crop production and environmental protection are typically represented by pH, electrical conductivity (EC), cation exchange capacity (CEC), and extractable P, K, and Al concentrations (Maddonni et al, 1999;Veum et al, 2021). Soil pH can affect nutrient availability to plants due to dissolution of nutrients at various pH levels (Maddonni et al, 1999;Veum et al, 2021). While acidic cations, such Al, Fe, and NH 4 , are available mostly at low pH to crops, basic cations, such as Ca, Mg, K, and Na, are available primarily at high pH.…”

“…While acidic cations, such Al, Fe, and NH 4 , are available mostly at low pH to crops, basic cations, such as Ca, Mg, K, and Na, are available primarily at high pH. As a result, most of the nutrients are available at neutral pH (6.5-7.0) where there are no toxic effects of elements to plants (Maddonni et al, 1999;Veum et al, 2021). The EC indicates soil salinity level that also affects crop production, as some crops are tolerant to high salinity level, but others are not (Jung et al, 2005).…”

“…For evaluating soil chemical properties as potential soil health indictors, it is necessary to examine if these properties are related to other soil properties and crop yields (Maddonni et al, 1999;Ohno and Hettiarichchi, 2018;Veum et al, 2021). Soil chemical properties can be related to each other and to other soil properties.…”

Soil chemical properties have often been related to some other soil properties and crop yields, but extensive evaluation of the relationships of soil chemical properties with other properties and long-term crop yields under dryland cropping systems is lacking. We related six soil chemical properties (pH, electrical conductivity [EC], cation exchange capacity [CEC], and inorganic P [IP], K, and Al concentrations) with 62 other soil physical, chemical, biological, and biochemical properties and crop yields at two long-term (14- and 36-year old) dryland farming sites in the northern Great Plain, United States. Treatments were rotations of no-tillage and conventional tillage spring wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), pea (Pisum sativum L.), and fallow with or without N fertilization. Soil samples collected to a depth of 0–15 cm in April 2019 were analyzed for soil properties and long-term crop yields were determined. Soil chemical properties were mostly correlated to each other at the short-term than at the long-term site. Based on the principal component analysis, EC, CEC, and IP, and K concentrations were associated with most of the physical, chemical, biological, and biochemical properties at both sites. The CEC, IP, and K concentrations were related to mean crop yields across years at individual or combined sites, but other chemical properties were not related to yields. We conclude that CEC, IP, and K concentrations may be used as potential chemical indicators of soil health that were related to most soil properties and crop yields under dryland cropping systems in the semiarid region.

The soil health concept has evolved over the past several decades, recognizing that the response of dynamic soil properties to management is dependent on site‐specific factors. The Soil Health Assessment Protocol and Evaluation (SHAPE) tool provides scores and benchmark values by forming soil peer groups based on site‐specific, climate‐edaphic characteristics. Data for model development were compiled from the Cornell Soil Health Laboratory and the Kellogg Soil Survey Laboratory databases. The SHAPEv1.0 interpretation curves produce scores between 0% and 100% for measured laboratory values that reflect the quantile within a population conditional cumulative distribution function along with measures of uncertainty. The original SHAPE tool was developed for soil organic carbon and has been expanded to include two wet aggregate stability methods, permanganate oxidizable organic carbon, autoclaved citrate extractable protein, and 4‐day microbial respiration. In addition, SHAPE provides site‐specific benchmark values at user‐defined percentiles within a given soil peer group. The difference between the actual measured value and the selected benchmark value represents the soil health opportunity gap. Case studies in Missouri and Texas show that the SHAPE scoring curves are sensitive to land‐use and management practices across multiple soil types and provide a regionally relevant interpretation of key soil health indicators.
