From Soil Threats to Soil Health: Prevention or Remediation
(Wiley, 2026-05-14) Suleymanov, Azamat; Cornu, Sophie; Coblinski, João Augusto; Montagne, David; Hessel, Rudi; Cousin, Isabelle; Bispo, Antonio; Saby, Nicolas P. A.
While soil threats and soil health are two interrelated, sometimes confused, concepts, we demonstrated here that a clear separa-tion between these two concepts associated to a mapping of both soil threats and soil health is necessary. Soil threats are com-monly defined as processes that may degrade the soil properties, functions or services, while soil health describes the state of thesoil at a given moment in time. As a consequence, an unhealthy soil is a soil which is degraded compared to a reference. Mappingsoil threats or soil health results then in different but complementary views of the situation. Mapping soil threats informs ac-tions to prevent soil degradation, while mapping soil health indicates the capacity of soils to provide functions and places whereremediation is needed. In this study, we demonstrated the differences between these concepts by comparing projection mapsfor 2050 of soil threats and soil health by considering soil compaction and loss of soil organic carbon (SOC) as soil threats andbulk density and SOC stock as basic soil properties to evaluate both soil threat and soil health in terms of the above-mentionedtwo soil descriptors. These maps were produced by digital soil mapping, taking into account changes in climate and land use inthe European Union (EU). Soil threats were mapped using soil property change between 1980 and 2050 as indicators, that is, adecrease in SOC stocks for SOC loss and increase in soil bulk density for compaction. For soil health assessment, as referencesare needed, we defined soil areas that could be considered as homogeneous by combining soil, climate and land use informationand defined for each area a threshold for soil health based on a quantiles approach. As a result, the obtained soil threat and healthmaps were very different, as healthy soils can be under threat but not have crossed the threshold yet, while unhealthy soils maynot be under threat anymore if no more degradation occurs. These results demonstrate that reading a map requires a good priorunderstanding of the meaning of the indicators used in order to be able to interpret it in terms of threat or health and to be ableto select appropriate metrics, which will not be the same in both cases. Indeed, while soil health maps identify degraded areaswhere the soil lost part or all its capacity to provide functions and that need remediation, soil threat maps offer vital informationabout potential vulnerabilities and areas requiring intervention or management strategies.
Harnessing Indigenous Rhizosphere Bacteria to Improve Plant Growth and Soil Microbial Activity in the Cultivation of Lactuca sativa L. Under Drought Stress Conditions
(Springer Nature, 2026) Woźniak, Małgorzata; Siebielec, Sylwia; Nowak, Artur; Siebielec, Grzegorz; Jaroszuk - Ściseł, Jolanta
Purpose. The application of plant growth promoting rhizobacteria (PGPR) is considered to have the potential to improve plant development in water-stressed agroecosystems. The current study was designed to screen PGPR for a broad spectrum of functional traits that that can enhance plant growth and soil microbial activity under drought stress conditions. Methods. This study characterised selected indigenous bacterial strains isolated from the rhizosphere of Lactuca sativa, focusing on their ability to enhance nutrient bioavailability, phytostimulation and produce biofilms and exopolysaccharides. The isolates’ functional potential was validated under controlled conditions by evaluating plant biomass and soil enzymatic activity under two treatments: moderate drought stress and well-watered control. Results. Using the biological GEN III test, the strains tested were found to be metabolically diverse. Furthermore, the results indicate that all strains solubilize phosphate, fix nitrogen and synthesize indole-3-acetic acid (IAA) - like compounds. Most of them were active producers of siderophores and 1-aminocyclopropane-1-carboxylate (ACC) deaminase. Out of 15 strains, 3 were strong biofilm producers, while all strains were extracellular polymeric substances (EPS) producers. The results of the pot experiment showed that decreasing irrigation significantly reduced the total biomass of lettuce by 36.2%. Lettuce plants inoculated with Bacillus spp. and Variovorax spp. strains exhibited a significant increase in dry weight, by 63.9% and 59.9%, respectively, under drought conditions compared to non-inoculated plants. Moreover, soils inoculated with the Bacillus spp. and Variovorax spp. strains showed higher dehydrogenase and phosphatase activities compared to the non-inoculated control; however, these differences were not statistically significant. Conclusions. Screening of the indigenous isolates revealed unique microbial traits with potential technological applications, including phosphate solubilization, biofilm and EPS production, nitrogen fixation, IAA synthesis, ACC deaminase activity, siderophore production, and high metabolic activity. Meanwhile, newly identified strains were found to enhance the development of butterhead lettuce under both optimal and reduced water availability.
Between host and parasite: The microbiome of Varroa destructor and its relationship with honey bees
(Elsevier, 2026) Marzec-Grządziel, Anna; Borsuk, Grzegorz
The study of the microbiome of the mite Varroa destructor is crucial for understanding parasite-host interactions and their potential health implications for honey bees (Apis mellifera). The aim of this research was to characterize the microbial diversity of Varroa destructor populations collected from the body surface of honey bees and compare it with microbiome of Apis mellifera. DNA isolation was performed using standard methods, followed by next-generation sequencing (NGS) of the V3-V4 region of the 16S rRNA gene. The obtained bioinformatic data underwent taxonomic analysis, enabling the identification of dominant bacterial genera present in the Varroa and Apis mellifera microbiome. Results revealed significant microbial diversity, with dominance primarily by bacteria belonging to the families Acetobacteraceae, Morganellaceae, and Segniliparaceae. The identified bacteria may play a critical role in the pathogenicity of Varroa destructor, directly or indirectly affecting the health and condition of bees. These findings provide new insights into potential therapeutic and preventive targets for protecting bee colonies against the detrimental effects of Varroa mites.
Straw Retention Enables the Yield and Quality Benefits of Reduced Tillage in Winter Wheat and Spring Barley: A Long-Term Study
(MDPI, 2026) Sinkevičienė, Aušra; Bogužas, Vaclovas; Steponavičienė, Vaida; Sinkevičius, Alfredas; Marcinkevičienė, Aušra; Wyzińska, Marta; Berbeć, Adam Kleofas; Kimbirauskienė, Rasa
Agronomic practices can modify cereal grain chemical composition and processing performance. Long-term evidence linking agricultural management with functionality-related quality remains limited, especially in terms of combined tillage x crop residue management strategy. We evaluated the effects of long-term tillage simplifications and straw management on productivity and processing-relevant traits of winter wheat and spring barley in a split-plot field experiment (Lithuania). Straw was either removed (S0) or chopped and retained (S1), and six tillage systems were compared (conventional ploughing (CP), shallow ploughing (SP), shallow cultivation (SOW), stubble over winter, no-till with cover crops (NTC), and no-till without cover crops (NT)). The yield and starch content of winter wheat and spring barley groats increased with the addition of straw and the application of SOW, NTC, and NT systems. The hectolitre mass of winter wheat and spring barley grains increased with the addition and removal of straw using SP technology. The protein content and wet gluten content of winter wheat and spring barley grains decreased, while the starch content increased, with the addition and removal of straw using SC technology. In wheat, protein content showed weak separation among treatments, while wet gluten and Zeleny sedimentation displayed mostly directional trends (wet gluten–sedimentation correlation: r = 0.844 under S0 and r = 0.984 under S1). In terms of the tillage systems, it can be stated that in most cases, SP and NT increased grain yield and improved quality indicators, while SC and NTC technologies showed opposite results. Soil-function assessment (CEI, 10–25 cm) indicated substantially higher integrated soil functioning under conservation agriculture (e.g., SOW/NTC/NT: 5.28–5.70) than under conventional systems (CP: 3.23). The results support framing sustainable soil management for cereal functionality as a system package: residue retention enables the productivity benefits of reduced-tillage systems while maintaining key quality proxies.
Impact of Nitrogen and Sulphur Fertilisation on Phosphorus and Silicon Content and Uptake by Biomass of Spring Wheat
(MDPI, 2026) Klikocka, Hanna; Podleśna, Anna; Podleśny, Janusz
Nitrogen and sulphur are among the most important plant nutrients (along with C, H, and O) and the main elements comprising the organic substance of plants. In this study, it is assumed that light soils (Cambisols) do not naturally meet the nitrogen and sulphur needs of spring wheat and, consequently, impact the phosphorus and silicon content in the plant biomass. Therefore, to determine the effect of N and S on the content and uptake of these elements at specific growth stages (BBCH 30–31: in leaves, BBCH 55–59: in whole plants, BBCH 89–90: in grain and straw), a three-year field experiment was conducted using different doses of nitrogen (0, 40, 80, and 120 kg ha−1) and sulphur (0, 50 kg ha−1). The results show that fertilisation with N and S had a significant effect on increasing the content and uptake of P and Si by phytomass in the phenostages studied. In general, as the N fertilisation dose increased, the yields of phytomass and grain increased. A beneficial effect of S on increases in green weight, straw, and spring wheat grain was found. A significant effect of N and S fertilisation on the growth of the Si:P ratio in individual parts of plants in the studied stages was also observed. A significant positive correlation between P and Si content was proven, indicating that the two elements do not act antagonistically towards each other. In contrast, a negative correlation was observed between the P content in plants and their Si uptake. Si is taken up more strongly by plants under conditions of N and S fertilisation, as evidenced by the increase in the Si:P ratio and the fact that plants accumulated on average 3.5 times more Si than P. The highest Si content was found in the green parts of plants in the BBCH 30–31 and BBCH 55–59 stages, while in BBCH 89–92, straw had nearly half that amount and grain contained a thousand times less silicon.
