“…The readily available, dissolved forms of phenolic compounds (aqueous extracts, WE) made up only a small part of the potential pool of antioxidants in the topsoil horizons of the studied soils. However, their role should not be marginalized, as these compounds, present by definition in low concentrations in soil solution, participate in many redox processes, including the formation of humic substances 19 . TAC in WE ranged from 5 to slightly over 21 µg g −1 for abandoned soils and farmlands to about 114 µg g −1 for forest soils.…”

“…Several studies imply that most of the antioxidants in soil can be found among the humic substances 15 – 18 . This was evaluated by Ziółkowska et al 19 ., who determined the important role of phenolic compounds in the processes of organic matter transformations in meadow soils, leading to the formation of humic substances. What is more, phenolics are considered more resistant to decomposition in soils compared to other organic matter sources, and thus have often been regarded a slow carbon pool in soil dynamics models 6 .…”

Antioxidants (AOX) in soils originate mainly from secondary plant metabolites and are pivotal in many redox processes in environment, maintaining soil quality. Still, little is known about the influence of land uses on their accumulation in soil. The aim of the paper was to determine the content of these redox-active compounds in the extracts of A horizons of abandoned fallows, arable and woodland soils. Total antioxidant capacity (TAC) of soils under various uses and vegetation was evaluated in different soil extracts using Folin-Ciocâlteu method. The contribution of humic acids to TAC was determined and antioxidant profiles estimated using the chromatographic GC–MS method. Forest soils exhibited the highest TAC (15.5 mg g−1) and AOX contents (4.34 mg g−1), which were positively correlated with soil organic carbon content. It was estimated that humic acids contribute to over 50% of TAC in soils. The main phenolics in woodland A horizons were isovanillic and p-hydroxybenzoic acid (p-HA), while esculetin and p-HA predominated in the abandoned fallows due to the prevalence of herbaceous vegetation. Cultivated soils were the most abundant in p-HA (56.42%). In the studied topsoils, there were considerable amounts of aliphatic organic matter, which role in redox processes should be further evaluated.

“…Just like straw, (lucerne) hay has been shown to increase nest building and reduce stereotypical behavior prior to farrowing (Edwards et al, 2019). Compared to straw, good-quality hay might provide additional nutritional benefits for lactating sows, including higher metabolizable energy and crude protein levels (Kamphues, 2004) as well as a high content of secondary plant substances (Ziolkowska et al, 2020), contributing to pigs' health. Hay might also be preferred as enrichment material over straw by young piglets as it is softer and therefore easier to chew.…”

Access to nest-building material in the preparturient period is beneficial for sows’ welfare. However, on slatted floors, long-stem forage can drop into the slurry and block the drainage system. As a compromise considering the needs of sows for access to adequate nest-building material, farrowing pens with slatted floors are equipped with dispensers (racks) accessible by sows. In this study, we developed a computer vision method to monitor the use of the racks with nest-building material. In total, 12 sows were included in the experiment from 5 days before farrowing to the end of farrowing. Hay rack use behaviors were labeled for all the sows, i.e., pulling hay, nose close to the rack, exploratory behavior, and bar biting. The object detection algorithm RetinaNet was used to extract centroids of parts of the sow’s body and the hay rack. Several feature variables were estimated from the centroids of detected parts of the sow’s body, and random forest was used for the classification of hay rack use behaviors. The model for the detection of pulling hay behavior had the best performance: 83.5% sensitivity, 98.7% specificity, and 98.6% accuracy. The distance between the sows’ nose and the hay rack was the most important feature variable, which indicated the importance of nose location for the recognition of behaviors in which pigs interact with other objects. The developed models could be applied for automated monitoring of the use of nest-building material in preparturient sows. Such monitoring might be especially important in sows housed on slatted floors.

“…They also contribute to form body structures (Wigglesworth, 1988) and coloration (Krishnan, 1951) in plant and animal bodies. Phenolic acids are considered as important precursors of humic substances in soils (Ziolkowska et al, 2020). They play multiple roles in soil formation and pedogenesis, that can directly influence the recycling of minerals as well as organic matter dynamics (Seneviratne and Jayasinghearachchi, 2003), by producing organic metal complexes, and also serve to increase the availability of micro and macro nutrients (Micales, 1997).…”

Bio-cycling of polyphenols in estuarine ecosystem have not been documented adequately among the floraand fauna thereof. Total phenolic contents, antioxidative potential and free-radical scavenging activityhave been analysed from three types of structural components (leaves of Acanthus illicifolius, and detritusloaded estuarine soil and a benthic fauna, Uca lactea annulipes), of the estuarine mangrove ecosystem of theNorth Eastern coastal belt of India. HPLC and MALDI-TOF Mass spectrometry analysis were performed toidentify and quantify the phenolic compounds. Results reveal that all the three samples contain Polyphenols that can be related through the process and pathways of eco-biological transformation. Though quantitativelyless, the presence of deprotonated polyphenols enriches the detritus laden soil. Interestingly, very fewparent ions of phenolic acids from leaf sample show up in the crab hemolymph. It contained new metabolitesconsisting of fragmented ions. This establishes the role of the fiddler crabs as agents participating in thebio-cycling of polyphenols and also depicts the interdependence of plants, animals, and soil for the exchangeof essential life supporting ingredients as an outcome of coevolutionary process.
