Abstract Polyacrylic acid (PAA), a synthetic superabsorbent polymer (SAP), enhances the maximum water holding capacity (WHCmax), stability, and aeration of soil but may directly or indirectly impact microbiome by altering properties. However, respective studies on its effects microbial activity in terms respiration functional diversity remain scarce. In this study, we examined PAA sand loam treated with at three concentrations (25, 250, 2500 mg Kg− 1) either incubated under constant moisture ten drying-rewetting cycles. During incubation, WHCmax, pH, were measured via headspace CO2 MicroResp assay. increased WHCmax both soils remained stable, except static moisture. Initially, lowered pH soils, which persisted only disappeared after one week. Further, cycles raised compared to conditions. suppressed substrate-induced (SIR) for carbohydrates, amines, carboxylic acids, particularly sand, where high led up 100% suppression. Responses varied: increased, while conditions reduced higher concentrations, respectively. Overall, whereas regimes texture dominant factors loam. This highlights dual SAPs: improving retention certain period, potentially reducing nutrient cycling, depending type, application rates, environmental long term.

Agricultural soils have been identified as potential reservoirs for plastic pollution, with adverse effects on soil properties. Primary sources of input in agricultural landscapes are associated the application sewage sludge or compost. Understanding and anticipated content is crucial mitigating pollution fields. This study presents one first investigations into other impurities, e.g. glass, seven organic fertilizers (biowaste compost, digested pig slurry, dry chicken manure, green waste sludge, a mixed digestate comprising 74 % renewable raw materials). Potentially visible foreign substances were assessed surface each fertilizer pile. No impurities could be detected digestate. For remaining fertilizers, collected, cleaned, visually described, weighed, photographed, size measured, chemically characterized using ATR-FTIR. The quantification revealed that particles most abundant contained all contrast to glass metal. An increasing trend particle number per m

The leachate generation is an inevitable consequence of landfill disposal, and thus it critically important to acquire effective approach preventing contamination the underlying soils groundwater aquifers. Currently, there no consensus on best approach; biological treatment membrane technology are widely tested but each has its own drawbacks. On other hand, superabsorbent polymers nowadays used in many liquid-absorbing applications have rarely been assessed for application treatment. In this study, a comprehensive analysis physicochemical parameters, ionic trace elements collected was carried out, four commercially available with different chemical compositions were respect their kinetics adsorption desorption, both load-free under-load, deionized water, tap leachate, respectively. results significant importance elucidating potential

The technology of seed coating with superabsorbent polymer (SAP) has the potential to mitigate negative impact drought on germination and crop establishment. However, their application surface can affect effectiveness pesticides used for treatment in protection against phytopathogens. In our work, influence Aquaholder®Seed fungicides germinating seeds spring barley cv. Bojos Laudis fungal pathogen Bipolaris sorokiniana was studied. One-half were first treated fungicides, then a applied. Fungicide efficacy evaluated Petri dish test pot under attack. Seed SAP did not negatively fungicide efficacy. percentage germinated seeds, seedling emergence, plant height, symptoms disease fungicide-treated variants significantly changed by application. Moreover, Laudis, alone partially protected amount DNA tissues different among treatments, while Bojos, increased coated but decreased combined fungicides. These results demonstrated that does pathogens.
