“…This explanation is also supported by the positive relationship between SOM and available micronutrients (Figure 4) (Ray et al, 2021). However, we found that orchards treated with engineering measures had the lowest available Fe and Mn, probably due to the lower SOM content (H. Liu et al, 2021;Wang et al, 2018).…”

Both biological and engineering measures have proven to be effective soil and water conservation practices for eroded environments, whereas how the soil quality varies with them remains unclear. In this study, we measured soil properties in the 0-to-100-cm soil layer of eroded orchards in southern China after 17-yr of application of different conservation measures. The purpose of the experiment was to examine the effect of biological (grass planting, intercropping) and engineering measures (terrace) on the soil quality of eroded orchards. We selected an orchard plot with traditional clean-tillage as control. In comparison, soil pH, organic carbon, total phosphorus, microbial carbon, available potassium, and available microelements contents increased significantly in orchards with biological measures, and the improvements were more dramatic in orchards planting grass in strips. However, biological measures significantly reduced the mean weight diameter of aggregates. Engineering measures significantly increased the soil pH of orchards but decreased the contents of available iron and available manganese. The soil quality index (SQI)

“…In this study, the concentration of trace metals (Fe, Mn, and Zn) increased with elevation, which is consistent with the temperature-plant physiology hypothesis that plants maintain higher nutrient concentrations in their tissues to maintain metabolic capacity and avoid damage caused by low and high temperatures (Figures 1 and 2). Wang et al (2018) observed the same phenomenon in the elevational distribution patterns of trace elements in plant-soil systems. At higher elevations, micronutrient concentrations were higher in roots of trees and shrubs to maintain physiological and ecological processes in colder environments (Wang et al, 2018), and the concentration of macroelements (N, K, Ca, Mg, S, and P) decreased significantly with elevation (Figures 1 and 2).…”

This finding was consistent with the temperature-biogeochemistry hypothesis: Soil biological activity was reduced under low-temperature stress, resulting in slow decomposition of soil organic matter, limited mineral nutrient supply, and reduced absorption of elements by roots ( Wright et al., 2004 ; Zhao et al., 2018b ).…”

Root chemical traits play a critical role in plant resource use strategies and ecosystem nutrient cycling; however, the chemical diversity of multiple elements of fine root and community chemical assembly belowground are poorly understood. Here, we measured 13 elements (C, N, K, Ca, Mg, S, P, Al, Fe, Na, Mn, Zn, and Cu) in the fine roots of 204 plant species along elevational transect from 540 to 2357 m of Changbai Mountain, China to explore the variation, diversity, and community assembly of root chemical traits. At the species level, the concentrations of macronutrients (N, K, Ca, Mg, S, and P) decreased, whereas the trace metals (Fe, Mn, and Zn) increased with elevation. Root chemical traits at the community level systematically shifted along elevational gradients showing a pattern similar to that at the species level, which were mainly influenced by climate and soil rather than species diversity. In general, the interactions of climate and soil were the main drivers of root chemical assembly for woody layers, whereas soil factors played significant role for root chemical assembly for herb layer. The chemical assembly of rock-derived element P was mainly driven by soil factors. Meanwhile, root chemical diversities were mainly regulated by species diversity, the interactions of climate and soil, and soil factors in the tree, shrub, and herb layers, respectively. A better understanding of plant root chemical diversity and community chemical assembly will help to reveal the role of chemical traits in ecosystem functioning.

“…In order to understand how micronutrients drive PSF, detailed information on plant responses to micronutrients alone and in combination is needed. For example, Wang et al (2018b) demonstrated a close link between concentrations of plant nutrients in soils and plant tissues on an elevational gradient, finding that soil was a stronger determinant of plant magnesium, calcium, manganese and zinc than elevation, while potassium and iron were decoupled. Further, litter decomposition in a range of forests was found to be tightly correlated with micronutrient concentration.…”

Plant-soil feedback: incorporating untested influential drivers and reconciling terminology

Background Plants condition the soil in which they grow, thereby altering the performance of subsequent plants growing in this soil. This phenomenon, known as plant-soil feedback (PSF), has garnered increasing interest. Experiments are moving from single species soil pairings in the glasshouse to community-level field trials. Consequently, our knowledge of the role PSF plays in shaping ecosystem functions has advanced. However, knowledge gaps remain. Scope Here, we explore intrinsic and extrinsic abiotic and biotic drivers of PSF such as maternal effects, plant functional traits, self-DNA, plant-plant competition, herbivory, interactions between soil organisms, temperature, drought, flooding, greenhouse gases, (micro)nutrients, plant-litter-soil feedback and priority effects. These drivers have begun to feature in experiments, thereby increasing our mechanistic understanding of PSF. Nonetheless, many of these topics have received insufficient coverage to determine general principles across larger temporal and spatial scales. Further, conflicting terminology has excluded PSF studies from reviews and meta-analyses. We review terms such as soil sickness, Janzen-Connell hypothesis, soil-related invasive species work, soil legacies, allelopathy and soil-related succession that overlap with PSF but are generally not named as such. Conclusion Holistic experimental designs that consider the continual reciprocal feedback between the extrinsic environment, plants and soil, as well as the unification of terminologies are necessary if we are to realise the full potential of PSF for understanding and steering ecosystem processes. Here, we compile outstanding questions related to PSF research that emphasis the aforementioned topics and suggest ways to incorporate them into future research in order to advance plant-soil ecology.
