Abstract:
... Ecological risks can vary dramatically depending on abiotic factors, such as soil properties and the background values of elements. This study developed a framework for an integrated risk assessment system to derive soil quality criteria (SQC) for heavy metals (HMs) applicable to different soil types and to assess ecological risks at a multi-regional scale. Through the construction of normalizatio ...

Abstract:
... Heavy metals (HMs) from smelters pose severe challenges to the environmental soil quality of surrounding farmlands, and threaten human health through the food chain. This study explored the environmental effects of smelting activities on farmland soil, and additionally assessed the enrichment, transfer and health risk of HMs in soil-wheat systems. Multiple characterization results were combined to ...

Abstract:
... Understanding how natural disasters affect soil quality and how it recovers is essential to improve soil management. We studied the effects of the 2010 Nanping landslides (China) on soil quality. We conducted an observational study using three levels of disturbance (‘destroyed’, ‘recovering’, and ‘undisturbed’). The ‘destroyed’ areas were sampled immediately after the landslide and the others were ...

Abstract:
... Crataegus and Berberis shrublands are natively distributed in Asia, Europe, North America and Africa. Despite the widespread distribution of these two species, the effect of pure and mixed canopy composition of these species on bioindicators of soil quality has received little attention. In the current research, the effect of pure [Crataegus (PC) and Berberis (PB)] and mixed [Crataegus and Berberi ...

Abstract:
... Microplastic contamination poses a significant threat to agroecosystem functioning, provoking a move away from the use of conventional oil-based plastics in agriculture, to biodegradable alternatives that may be degraded over a shorter timescale. The impact of these bioplastics on plant and soil health, however, has received relatively little attention. Here, we investigated the effect of soil loa ...
... The ultimate purpose of phytoextraction is not only to remove heavy metals from soil but also to improve soil quality. Here, we evaluated how the joint effect of Streptomyces pactum (strain Act12) and inorganic (Hoagland's solution) and organic (humic acid and peat) nutrients affected the phytoextraction practice of cadmium (Cd) and zinc (Zn) by potherb mustard, and the microbial community composi ...

Abstract:
... Soil organic matter (SOM) is a critical component of the soil system and a sensitive indicator of soil quality. We aimed to investigate the response of SOM pools to different land uses and management in irrigated croplands of the semi-arid region of northeast Brazil. Four sites irrigated under long-term (29 years) land uses were selected: banana (B1 and B2); elephant grass (EG) - perennial systems ...

Abstract:
... Reasonable irrigation and fertilization practices can not only improve soil quality, but also increase crop yield, and water-fertilizer use efficiency. However, it is still unclear that the micro-irrigation and fertilization mode is conducive to improving the soil comprehensive environment, the mango yield and water-fertilizer use efficiency in the dry-hot region. The effects of regulated deficit ...

Abstract:
... The global food system is highly dependent on grains, the production of which requires annual biomass turnover, which reduces soil health and undermines sustainability. Investments in diverse perennial grain-producing crops that produce abundant biomass while enhancing ecosystem services are needed to sustain global food production and growing biomass demands. ...

Abstract:
... Renovating pastures to increase forage species diversity is a burgeoning practice among producers. Over a century of grassland and small-plot research suggests that increasing plant diversity can lead to improved pasture productivity, resilience, and soil health. However, it remains hard to decipher how these benefits translate to grazed production systems given the limited experimentation in real ...

The mass production and application of graphene have gradually expanded from academic research to industrial applications, which will inevitably lead to graphene entering the soil actively and passively. Therefore, the relationship between graphene and the pedosphere has attracted a lot of attention in the last decade. The most important question is whether graphene will harm soil health.

Abstract:
... Among its many functions, soil represents the active natural medium for plant growth. Different soils have various structural characteristics, that correspond to their qualitative parameters in terms of physical, chemical, and biological fertility. Because of their extremely slow formation processes, soils are also a non-renewable resource, easily subject to degradative processes. Among their mine ...
