Models and Methods for Evaluating the Soil-Based Ecosystem Services of Agricultural Soils-A Global Systematic Review
(MDPI, 2026-05-29) Pindral, Sylwia; Wnuk, Agnieszka; Coblinski, João Augusto; Niedźwiecki, Jacek; Smreczak, Bożena
Soil-based ecosystem services (SESs) are various benefits provided by soils to society or the environment, and their assessment supports sustainable agricultural soil management aimed at preventing further soil degradation. Individual SES evaluation procedures need a set of adequate indicators to support countries in monitoring the status of soil health. Among them, soil organic carbon (SOC) is indicated as one of the main, widely accepted and practicable attributes reflecting the proper functioning of soils. This paper aimed to present the recent state-of-the-art on SOC’s role in modelling and mapping individual SESs. Therefore, the PRISMA method was applied to select 138 research articles. The results showed that SOC data has been applied in evaluations of provisioning, regulating and supporting SESs. Based on our findings, we recommend paying special attention to SOC monitoring systems at different scales and database preparations following the primary modelling rule, garbage in—garbage out, enhancing the reliability of various models and their applicability across different scales. The proper selection of input data and assessment methods is crucial for accurately evaluating ecosystem services while minimising the risk of misinterpretation or ineffective policy and management decisions. Despite the existence of many types of models for the evaluation of SESs, we want to highlight that for the preservation of consistency and harmonisation, the proper modelling framework should be kept. In our studies, we highlighted that a comprehensive modelling workflow that integrates DSM-derived SOC data, scale-aware validation and uncertainty propagation into SESs is crucial to achieve reproducible, high-quality modelling approaches. Future research should focus on a systematic review of the usability of SES indicators, refining methodologies and expanding their use in national-scale assessments to support sustainable decision making.
Optimization of supercritical CO₂ extraction of Petasites hybridus rootstocks using Box–Behnken design: Yield modeling, chemical profiling, and evaluation of COX-2 inhibitory activity
(Elsevier, 2026-05-01) Kulinowski, Łukasz; Pecio, Łukasz; Luca, Simon Vlad; Kurach, Łukasz; Pawlak, Bernard; Florkowski, Grzegorz; Budzyńska, Barbara; Skalicka-Woźniak, Krystyna
Petasites hybridus extracts are valued for their antimigraine and anti-inflammatory properties but require pyrrolizidine alkaloids-free and compositionally consistent extraction methods. Supercritical CO₂ extraction offers an alternative to organic solvents, yet its performance for butterbur has not been systematically optimized or linked to chemical and biological outcomes. This study aimed to optimize extraction conditions using Box–Behnken design and evaluate extraction yield, sesquiterpenoid content, pyrrolizidine alkaloids levels, and cyclooxygenase-2 (COX-2) inhibitory activity across the investigated extraction conditions. Fifteen extracts were prepared across a three-factor Design of Experiments (DOE). Sesquiterpenoids and pyrrolizidine alkaloids were quantified using UPLC-PDA-MS/MS. COX-2 inhibition was assessed using a fluorometric screening assay. Data were modelled using response surface methodology and multivariate regression analysis. Extraction yield responded to temperature and CO₂ consumption, while sesquiterpenoid composition remained stable. Supercritical CO₂ extraction with the dried plant material yielded pyrrolizidine alkaloids-poor extracts (15–91 µg/g), whereas PAs content increased > 100-fold after hydrating the same plant material to a 40% moisture content and continuing the process. COX-2 inhibition was moderate (49–65% relative to the positive control, Celecoxib), reproducible, and insensitive to extraction parameters or individual metabolite levels. Overall, supercritical CO₂ extraction provides a scalable method for producing compositionally stable P. hybridus extracts with low pyrrolizidine alkaloids content. While extraction yield can be efficiently optimized, the biological activity appeared to be matrix-driven. Future enhancement of anti-inflammatory potency will require fractionation or co-solvent strategies rather than modifications of operating supercritical CO₂ extraction conditions.
Does Crop–Livestock Integration Enhance Economic Resilience in Organic Farming? Evidence from Polish FADN During the 2020–2022 Multi-Crisis Period
(MDPI, 2026) Madej, Andrzej; Berbeć, Adam Kleofas
Agriculture, as a production sector, is exposed to external shocks. The instability of agricultural markets, changes in prices of inputs, dropping crop prices, or changes in climate patterns put their economic resilience to the test. Agroecological diversification of production is widely cited as a key adaptive strategy to increase farms’ resilience to these shocks. At the same time, empirical evidence linking crop diversity to economic stability across different production systems remains limited. The aim of the study was to assess whether the integration of more complex crop rotations and livestock production increases the economic resilience of organic farms compared to stockless organic farms and conventional farms. The analysis utilized data from the Polish FADN covering the multi-crisis period of 2020–2022, which included the COVID-19 pandemic, Russia’s war against Ukraine, and the sharp rise in fertilizer and energy prices. Farms were grouped by production type. Crop diversity was assessed using the Shannon–Wiener index (H′) and the Pielou evenness index (J′). The economic resilience of tested farms was determined based on their income, income variability during the study period, and the ability to maintain income above the parity threshold. The results indicated the existence of different pathways for building resilience. Organic farms with permanent crops and field crops were characterized by the highest crop diversity on arable land, while organic farms with dairy cows had the highest overall economic resilience, despite relatively low crop diversity on arable land. This phenomenon can be explained by the high proportion of permanent grasslands, which promoted feed self-sufficiency and the internal circulation of nutrients. The results indicate that in organic systems, the integration of crop and livestock production, based on permanent grassland, may be a more effective way to strengthen economic resilience than crop diversification on arable land alone.
Comparative phytochemical, antioxidant, and hemostatic studies of leaf and stem extracts of Rhazya stricta Decne. in human plasma and human peripheral blood mononuclear cells in vitro
(Frontiers, 2026-05-11) Hamed, Arafa I.; Mohamed, Amal A. A.; Ben Aissa, Mohamed Ali; Kontek, Bogdan; Kluska, Magdalena; Woźniak, Katarzyna; Kowalczyk, Mariusz; Kowalska, Iwona; Oleszek, Wiesław; Olas, Beata
Introduction: Rhazya stricta Decne. is considered an important medicinal plant that is rich in secondary metabolites containing anticancer alkaloids. Several indole alkaloid classes have been identified from the various parts of R. stricta, but the cytotoxic potentialities of only a few of these metabolites are known.Methods: In this study, an applied analytical method was used to determine the alkaloids in R. stricta from the stem (RS) and leaf (RL) and their extracts.Results and Discussion: This study tentatively elucidated 10 new compounds of indole alkaloids from the various parts of R. stricta. Among them, six alkaloidal glycosides had not been detected in natural resources. This investigation also examined the in vitro protective results of the four R. stricta stem (A–D) and leaf (A′–D′) extracts, each having a different group of compounds—indole alkaloids, against oxidative stress activated by H2O2/Fe2+ in human plasma in vitro. In addition, we estimated the effect of these plant extracts on DNA fragmentation in human peripheral blood mononuclear cells (PBMCs). Another aim of these in vitro experiments was to determine the result of A–D and A′–D′ on selected hemostatic parameters of human plasma, such as the activated partial thromboplastin time, prothrombin time, and thrombin time, and on the viability of PBMCs. Based on our results, we demonstrate for the first time that tested extracts of the leaves and stems of R. stricta containing different indole alkaloid compounds (especially two tested preparations from R. stricta leaf—C′ and D′) are good antioxidant in vitro models, depending on the dosage, and they may have some promising actions in vivo. For example, we observed a significant difference in the level of DNA damage induced by H2O2 in the experiment with A–D and A′–D′. Two tested extracts from R. stricta leaf (C′ and D′, at all concentrations used) were also found to protect plasma against H2O2/Fe2+—induced lipid peroxidation. In addition, preparation C′ does not induce cytotoxicity. The potential of the metabolomics of extract C′ may be correlated to the presence of rhazisidine, secamine, and their derivatives.
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.
