Special Issue Information

Dear Colleagues,

Soil health can be regarded as soil’s ability to perform diversified services and functions, including sustainability in plants’ production along with environmental improvements or/and maintenance. Common farming techniques in agriculture, such as the application of pesticides or fertilizers and monocropping practices, can depreciate soil over time, leading to a series of challenges that require the use of more inputs, which further contribute to climate change. Understanding the vital role of soil, especially with changing environments, has been attracting the scientific community’s growing attention and has been the target of relevant research. Sustainable methods (crop rotation, no-until or low-until practice, cover cropping, and sustainable pest management techniques) connected with regenerative farming systems (use of compost, adding animals to the farm system) can improve the soil environment, concurrently enhancing crop quality.

Considering that not all of the challenges have been addressed by multiple literature reports pertinent to the current topics, there are still many concerns that need to be discussed. In this respect, a deeper understanding is of crucial importance regarding how to manipulate farming practice and the soil’s physical (bulk density, water-holding capacity, soil aggregate stability), chemical (pH, organic carbon and nutrient status), and biological (microbial diversity and composition, soil enzymes, respiration, etc.) indicators, with the aim to build healthier ecosystems.

This Special Issue focuses on the development and assessment of multiple methods which relate to the functional soil processes/practices used to evaluate soil health status. For this reason, we welcome highly interdisciplinary quality articles from different research fields including agriculture, biology, chemistry, physics, and engineering that focus on innovative methods and their interactions that lead to high yield performances.

Soil quality, characterized by its physical, chemical, and biological properties, is closely linked to soil management. Reducing soil disturbance can limit soil degradation; however, tillage is still considered essential, particularly on poorly drained soils. This study aimed to identify the optimal tillage practices for winter wheat crops following long-term no tillage practice and crop rotation (2020–2023). Additionally, it highlights the considerable advantages of particular tillage practices in emphasizing their role in enhancing soil health and sustainable agriculture. The experiment followed a randomized complete block design with three replications and two tillage practices: no tillage (NT) and conventional tillage (CT). The research was carried out on a cambic chernozem soil type. The results revealed that physical properties such as bulk density (BD) can increase or decrease under NT, while soil water content (SWC) increased under the same system. The status of water-stable aggregates (WSAs) also improved in NT (88.41%) due to the incorporation of cover crop or plant residues in the 0–10 cm depth. Notably, the highest SWC value at harvest was obtained in the 0–10 cm soil depth, under NT, reaching 24.47%. Grain yields over four years of research were also influenced by tillage systems, resulting in mean yields of 6070 kg/ha for CT and 4285.25 kg/ha for the NT system. The Pearson correlation coefficient was calculated for the soil physical properties considered in pairs. Between BD and water-stable aggregates (WSAs), there was a moderate positive correlation (r = 0.458**) and statistical significance, but no linear correlation between BD and SWC (r = 0.089), and between WSAs and SWC (r = 0.026). Generally, using NT, which reduces soil disturbance and maintains residues on the surface, could contribute to land sustainability and climate mitigation in north-east Romania. Full article

Soil health is essential for sustainable agriculture, influencing ecosystem health and orchard productivity of plum orchards. Global challenges such as climate change and soil contamination threaten to affect fertility and food security, requiring sustainable practices. The study assessed the effect of different orchard management practices on soil quality and nutrient distribution in Prunus domestica L. orchard located on the Moldavian Plateau in northeastern Romania under temperate humid subtropical climate conditions. Two systems were analyzed: conventional (herbicide-based) and conservative (cover crop-based). Soil samples (0–20 cm and 20–40 cm) were analyzed for soil organic carbon (SOC), total nitrogen (Nt), available phosphorus (P), and potassium (K). Results showed that conservative management improved soil health by increasing SOC nutrient cycling, mainly through organic matter inputs. Compared to 2022, the effectiveness of phosphorus in the conservative management system significantly increased (by 6%) in 2023, while potassium content decreased (by 30%), suggesting potential nutrient competition or insufficient replenishment under organic practices. SOC levels remained stable, supporting long-term carbon inputs. Conventional management maintained phosphorus and potassium but showed lower SOC levels and higher risks of soil fertility depletion. Strong correlations between SOC and nutrient indicators emphasize the critical role of organic inputs in nutrient mobilization. The findings indicate that cover crops are essential for sustainable soil management by enhancing carbon sequestration and nutrient cycling, thereby supporting the long-term sustainability of agricultural systems.

Soil degradation is a critical challenge to global agricultural sustainability, driven by intensive land use, unsustainable farming practices, and climate change. Conventional soil monitoring techniques often rely on invasive sampling methods, which can be labor-intensive, disruptive, and limited in spatial coverage. In contrast, non-invasive geophysical techniques, particularly ground-penetrating radar, have gained attention as tools for assessing soil properties. However, an assessment of ground-penetrating radar’s applications in agricultural soil research—particularly for detecting soil structural changes related to degradation—remains undetermined. To address this issue, a systematic literature review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. A search was conducted across Scopus and Web of Science databases, as well as relevant review articles and study reference lists, up to 31 December 2024. This process resulted in 86 potentially relevant studies, of which 24 met the eligibility criteria and were included in the final review. The analysis revealed that the ground-penetrating radar allows the detection of structural changes associated with tillage practices and heavy machinery traffic in agricultural lands, namely topsoil disintegration and soil compaction, both of which are important indicators of soil degradation. These variations are reflected in changes in electrical permittivity and reflectivity, particularly above the tillage horizon. These shifts are associated with lower soil water content, increased soil homogeneity, and heightened wave reflectivity at the upper boundary of compacted soil. The latter is linked to density contrasts and waterlogging above this layer. Additionally, ground-penetrating radar has demonstrated its potential in mapping alterations in electrical permittivity related to preferential water flow pathways, detecting shifts in soil organic carbon distribution, identifying disruptions in root systems due to tillage, and assessing soil conditions potentially affected by excessive fertilization in iron oxide-rich soils. Future research should focus on refining methodologies to improve the ground-penetrating radar’s ability to quantify soil degradation processes with greater accuracy. In particular, there is a need for standardized experimental protocols to evaluate the effects of monocultures on soil fertility, assess the impact of excessive fertilization effects on soil acidity, and integrate ground-penetrating radar with complementary geophysical and remote sensing techniques for a holistic approach to soil health monitoring.
