“…Unlike our results in Mollisol, erosion resulted in significant increase of loess soils C limitation in plots with crops (Figure 2d). On the one hand, the loess soils are more susceptible to erosion due to their loose texture and poor soil structural stability compared with Mollisol (Chen et al, 2023) and thus had greater C loss (−186.7 mg m −2 ) than Mollisol (−110.2 mg m −2 ) (Figure S4), which may result in greater C limitation in loess soils. On the other hand, the loess soils had fewer nutrients than Mollisol (Tables 2 and 3) and thus smaller aboveground biomasses in loess soils than those in Mollisol (Figure S3).…”

Soil microbial metabolism plays important role in supporting soil services and functionalities, but is usually restricted by the availability of soil nutrients. Although soil microbial metabolism limitation (SMML) has been widely addressed regarding to various driving factors, its response to erosion was not examined, but is urgently needed given the important influence of erosion on global environments. To understand how erosion affects SMML and whether erosion's effect varies with tillage practices and soil types, we conducted a simulated erosion experiment to compare the eroded and non‐eroded plots with contrast soils (Mollisol vs. loess soils) and managements (conventional tillage vs. no‐tillage in plots with vs. without crops). We measured soil extracellular enzymatic activities and quantified SMML with extracellular enzymatic stoichiometry models. In both soils, the microbes were limited by carbon (C) and phosphorous (P), but not by nitrogen, and that the microbial C and P limitations were greater in Mollisol than loess soils. For the Mollisol, erosion significantly increased the relative C limitation, whereas the presence of crops eliminated this increase. For the loess soils, erosion enhanced the relative C limitation regardless of crop presence and tillage management. Erosion consistently increased microbial P limitation in plots with crops, with greater effect under no‐tillage (+2.9%) than conventional tillage (+0.7%) conditions regardless of soil types (P < 0.05). In plots without crops, microbial P limitation was increased by erosion under no‐tillage (+2.1%) but was decreased under conventional tillage (‐5.6%) (P < 0.05). Additionally, conventional tillage exacerbated microbial C limitation but alleviated microbial P limitation. These results indicated that erosion shifted microbial C and P limitations depending on soil types, tillage practices and the presence of plant, highlighting the importance of considering all these factors when assessing soil microbial metabolic limitation at various spatial scales.This article is protected by copyright.

“…According to the meteorological data from 1971 to 2018, the mean annual temperature is 0°C and the mean annual precipitation is 546 mm, however, approximately 67% of the precipitation falls as rainfall between June to August, while 15% falls as snow between November to February (H. Q. Li et al, 2021). The major soil is known as Isohumosols in Chinese Soil Taxonomy and Udic Argiborol in United States Department of Agriculture system, developed from lacustrine and fluvial sand beds that formed during the Quaternary period (S. Q. Chen et al, 2023; P. Z. Zhu et al, 2023). Currently, summer cropland is the dominant land use type in the study watershed, accounting for 78.9% of the total watershed area (Wang et al, 2023).…”

“…As one of the four major black soil regions of the world, the black soil region of northeast China covers an area of 1.09 × 10 6 km 2 (S. Q. Chen et al, 2023). Due to its flat terrain, high soil fertility, and superior soil quality, despite this region only being 8.2% of China's land area, its grain production accounts for approximately 20% of China's grain production (Xie et al, 2019).…”

Soil infiltration properties (SIPs) are crucial soil hydraulic parameters for hydrological and erosion models as they regulate the movement of water and nutrients within the soil. Tillage practice can significantly impact the hydrological and erosional processes of sloping farmland by changing SIPs through altering soil structure. Nevertheless, knowledge regarding the effects of short‐term conservation tillage on SIPs is unclear, which greatly limits the management of soil and water resources of sloping farmland. This study aimed to clarify the potential impact and underlying mechanisms of short‐term implementation of conservation tillage on SIPs under three typical tillage management types: conventional downslope tillage (DT), conservation contour tillage (CT), and no‐tillage (NT) in the black soil region of Northeast China. SIPs of initial infiltration rate (IIR), steady infiltration (SIR), and hydraulic conductivity (Ks) were determined by a field disc infiltration experiment under pressure heads (h) of −3, −1.5, and 0 cm. The results revealed that short‐term implementation of conservation tillage management degraded SIPs, with a significant difference observed between DT and NT. In comparison to DT, the mean SIPs of IIR, SIR, and Ks of CT decreased by 27.5%, 31.2%, and 28.6%, and the corresponding reduced values of NT were 54.1%, 65.0%, and 65.5%, respectively. SIPs were significantly correlated with soil texture, bulk density (BD), capillary porosity (CP), total porosity (TP), field capacity (FC), saturated water content (SSWC), and organic matter content (SOM). Among these influencing factors, the variations in SIPs among different tillage management and soil layers were primarily influenced by differences in clay and gravel contents, FC, and SSWC and SSWC played the most critical role. These results highlight the substantial impacts and clarify the mechanisms of short‐term conservation tillage on SIPs, which is helpful for understanding the potential effect of short‐term conservation tillage management on hydrology and erosional processes, thereby improving the sustainable utilization of arable land.

“…Recognize the quality of eroded soils is essential since the erosive phenomenon represents a serious problem for food sustainability, mainly because the soil is a finite resource. In turn, the deterioration of soil quality, through loss of fertility and erosion, can limit self-sufficiency, security and food sovereignty [22][23][24].…”

Soil Quality Assessment in Response to Water Erosion and Mining Activity

Erosion significantly decreases the depth of a soil, the nutrients available for plants, the organic matter and, consequently, the productivity of the edaphic environment. Due to the above considerations, the objective of this study was to evaluate, through various properties, the quality of two eroded soils, one eroded by water and the other by mining activity, amended with biosolids. The quality for both soils was estimated through the selection of a minimum set of data by means of principal component analysis (PCA) and the subsequent realization of correlations, multiple regressions and finally calculations of normalized values (Vn) of those properties considered as indicators of soil quality. According to the results, inorganic nitrogen (NI) and respiratory activity (RA) were the properties selected as indicators to assess quality. For soil eroded by water and by mining activity, NI presented a low and very low quality, respectively (class 4 and 5 of quality according to the calculation of Vn). The quality of RA in soil eroded by mining extraction was very high (quality class 1 according to Vn), and thus it can be considered an ideal indicator for the evaluation of soil quality due to its sensitivity to anthropogenic changes (mining) in soil.
