The Expert Group for Technical Advice on Organic Production (EGTOP) was requested to advise on the use of several substances with plant protection or fertilising effects in organic production. The Group discussed whether the use of these substances and methods is in line with the objectives and principles of organic production, and whether they should be included in Commission Implementing Regulation (EU) 2021/11652. Recommendations with respect to Annex I to Regulation (EU) 2021/11652: • The Group recommends authorising calcium carbonate also for plant protection. It should be included in Part 2 of Annex I to Regulation (EU) 2021/11652 with the restriction ‘Only of natural origin’. Recommendations with respect to the production (‘forcing’) of ornamental bulbs and chives on pure water or an allowed growing medium: • The Group recommends authorising the forcing of flower bulbs outside the soil in water or authorised substrates. Point 1.3 of Annex II to Regulation (EU) 2018/8481 as follows : ‘By way of derogation from point 1.1,the following shall be allowed: the obtaining of chicory heads including by dipping in clear water and the forcing of flower bulbs outside the soil in pure water or authorised substrates shall be allowed’. • The Group could not reach a common conclusion regarding the forcing of chives and therefore does not give a recommendation.

The Expert Group for Technical Advice on Organic Production (EGTOP) was requested to advise on the use of sulphur dioxide (SO2) in malting during the kilning process in organic production, on ammonium hydroxide (NH4OH) as a processing aid for the production of ethyl alcohol of agricultural origin and on sulphuric acid (H2SO4) as a processing aid in the production of organic pea protein. The Group discussed whether the use of these substances is in line with the objectives and principles of organic production and whether they should therefore be included in Annex V, part A of Commission Implementing Regulation (EU) 2021/11652. The Group recommends the following: • not to include sulphur dioxide as a processing aid in malting; • not to include ammonium hydroxide as a processing aid for the production of ethyl alcohol of agricultural origin; • not to include sulphuric acid as a processing aid in the production of organic pea protein.

Vaccinium uliginosum (bog bilberry) is widely consumed in North America and Asia but has been historically avoided in many parts of Europe due to its alleged poisonous effects. We aimed to address this discrepancy in a systematic way with a combined phytochemical and ethnopharmacological approach, using UHPLC and UHPSFC for the chemical analysis, model organisms Caenorhabditis elegans and human liver cells GFP-Huh-7 for the bioactivity and toxicity testing, as well as fermentation experiments. Phytochemical analysis revealed minimal differences in the metabolite pattern between European and North American samples, with no evidence of toxic alkaloids or harmful secondary metabolites. Extracts exhibited no strongly toxic effects in the tested concentrations, neither in vitro (cell viability) nor in vivo (C. elegans). Berries infected by Monilinia megalospora showed altered flavonoid and anthocyanin contents but no increased toxicity. Notably, bog bilberries demonstrated a fermentation potential superior to Vaccinium myrtillus, resulting in an alcohol content of 4.8–5.8% ABV in unsweetened juices, thus potentially explaining historical accounts of inebriation. In conclusion, direct toxicity derived from these fruits is unlikely, but the alcohol content due to fruit fermentation is a plausible explanation for the folklore names (“drunk, inebriating berry”). However, additional factors such as human error, individual intolerance, or endophytic activity need to be considered.

As droughts become longer and more intense, impacts on terrestrial primary productivity are expected to increase progressively. Yet, some ecosystems appear to acclimate to multiyear drought, with constant or diminishing reductions in productivity as drought duration increases. We quantified the combined effects of drought duration and intensity on aboveground productivity in 74 grasslands and shrublands distributed globally. Ecosystem acclimation with multiyear drought was observed overall, except when droughts were extreme (i.e., ≤1-in-100-year likelihood of occurrence). Productivity losses after four consecutive years of extreme drought increased by ~2.5-fold compared with those of the first year. These results portend a foundational shift in ecosystem behavior if drought duration and intensity increase, from maintenance of reduced functioning over time to progressive and profound losses of productivity when droughts are extreme.
