‪Great opportunity: full @ukri.org funded PhD Studentship with 4 years fees, stipend (£19237 pa) and full Research Training Support Grant, working with Prof Ian Bull, Director of the National Environmental Isotope Facility and my @ercrefresh.bsky.social team! Starts 10/2025 shorturl.at/AJREj 🧪

Spoke on BBC Radio 4 Farming Today this morning on the implications of the Cunliffe Report for UK farmers and freshwaters, explaining some of the key findings from our @ukri.org funded QUANTUM programme on livestock impacts on www.bbc.co.uk/sounds/play/... 🧪

Today saw the publication of Nitrogen: Time to Reduce, Reuse, Recycle — a @houseoflords.parliament.uk report from the cross-party Environment and Climate Change Committee, into which UKCEH scientists provided written and oral evidence. Learn more: committees.parliament.uk/committee/51... 🧪 1/

The report helps highlight the need to tackle the issue of N pollution and management in a more joined-up, holistic way across sectors to reduce, recycle and reuse nitrogen. Full report: publications.parliament.uk/pa/ld5901/ld... #nitrogen #NitrogenPollution 2/2

UK House of Lords completes its inquiry into nitrogen and launches its report with a clear call to action! It was a pleasure to work with the parliamentarians who quickly recognized the urgent need and economic opportunity of a joined-up nitrogen strategy. committees.parliament.uk/committee/51...

British NZN raises €5.6 million for biofertiliser solution delivering a ‘green discount’ for farmers NetZeroNitrogen (NZN), a Nottingham-based AgTech company on a mission to end reliance on synthetic nitrogen fertilisers (SNFs), has raised a €5.6 million Seed round to make key hires in ASEAN…

South Australia ‘helpless’ in face of deadly marine algal bloom spreading to Adelaide beaches State’s environment minister warns bloom unlikely to disappear any time soon as testing for toxic algae continues at 14 Adelaide sites www.theguardian.com/environment/...

A vast toxic algae bloom has sparked growing concern in Australia as it lingers off the south coast, killing hundreds of marine species and disrupting fisheries

Australia's toxic algae bloom is 'natural disaster' - premier says #Australia

🚨Just out in @natfood.nature.com! 🚨A News&Views article by Sergiy Medinets and @marknitrogen.bsky.social explores the new data-driven conceptual framework by Mi et al. for benchmarking sustainable nitrogen management in cropping systems. buff.ly/Xi9TRJN 🧪 #NitrogenManagement 1/

Nice to see it published! This represents a step toward the practical implementation of a classic partial-nutrient-budget–inspired concept for region- and crop-specific nitrogen benchmarking to achieve sustainable N management. rdcu.be/evOEF @towardsinms.bsky.social @marknitrogen.bsky.social

A high-profile 'carbon capture' project doesn't even capture enough co2 to cover it's own pollution, making it a net emitter Projects like this get plenty of soft media coverage of their promises, none have delivered There is no silver bullet, climate pollution must be stopped at the source

Overfertilization causes soil to become acidic, negatively affecting crop production. Reducing the use of agrochemicals is essential to protecting food systems. Check out UNEP’s efforts to #BeatNitrogenPollution: unep.org/interactives...

#Luftverschmutzung als Todesursache auf einem Totenschein? Ja, das gibt es. In 🇬🇧 im Fall eines neunjährigen Mädchens. Wer sich für die Hintergründe interessiert, kann auf deutsch in meinem Sachbuch nachlesen bastei-luebbe.de/Buecher/Sach... oder bei der Europäischen Umweltagentur auf englisch.

“I’m a farmer. We don’t want to admit that we messed up, but we did. We’ve over-applied fertilizer, we’ve over-applied water, and we drove nitrates down into the ground, and we have nitrates in groundwater.” www.agriculture.com/pillen-admit...

Was die EU übrigens weiterhin aus Russland importiert #Stickstoffdünger - der nicht zwar „zu 90% aus Erdgas besteht“. Was stimmt: Dünger wird aus Ammoniak gewonnen, hergestellt in Russland mit Erdgas. #Ammoniak ist auch Rohstoff f Munitionsherstellung. #nitrogen www.tagesschau.de/wirtschaft/w...

Auch hier spielt #Stickstoff im Überfluss rein, es fördert im Zusammenspiel mit zu viel #Phosphat Algenblüten. Auch giftige #everywhereandinvisible

Cutbacks have gutted the staff at NOAA’s Great Lakes Environmental Research Laboratory, who work to protect the public from toxic algal blooms. Severe spending limits have made it difficult to purchase ordinary equipment for processing samples, such as filters and containers.

Apparently storms on Jupiter can rain huge, mushy ammomnia snowballs, creating layers of ammonia which will stay trapped deep within the atmosphere until some future storm comes along and dredges it all back up 🔭🧪 www.space.com/the-universe...

Russian ammonia flowing freely through Finland to the European markets. Wagons at the Kouvola railway station this morning.

The EU's dependence on imports of nitrogenous fertilisers and the increased share of Russia in 2024 are a growing source of concern. My blog post discusses capreform.eu/import-depen...

As I talked about ammonia in the atmosphere of Neptune, a child was able to find his way in the dark to the front of the planetarium, tug on my shirt, and let me know that he once had ammonia. Better now though. 🔭

Ok, #WelttagdesBuches war jetzt dann gestern .. meine Entschuldigung: ich hab mit dem Update Erde Team an einer überirdischen Podcastfolge gearbeitet - kommt Freitag früh in Eure Podcast-App 🎧 - also: hören oder lesen 😘 #Stickstoff #everywhereandinvisible

"Ammonia now dominates oceanic reactive nitrogen deposition in coastal regions where the country has much higher ammonia emissions than oxidized nitrogen emissions"... #BeatNitrogenPollution

A short video clip from 'Midnight Science Club' of Steven ‘Jake’ Jacobs, known here as Wizard IV, adds an old copper penny (no Zn) to nitric acid (HNO3). There's a "vigorous" reaction, lots of nitrogen dioxide gas, a green liquid forms, is capped with a beaker, then turns blue. What happened?

Experts state unequivocally, based on solid evidence: "The current extent of meat production & consumption has profound negative impacts (...). Animal ag is a major driver of emerging zoonotic diseases, antimicrobial resistance, climate change, biodiversity loss, deforestation & nitrogen pollution."

New paper in The Lancet Planetary Health where we show that Nitrogen enrichment not only substantially increases the pollen production of grasslands, but also the pollen allergenicity 🤧.

Paris. This is what happens to a city when it limits ICE car use, increases green spaces and encourages bicycle use. "Levels of fine particulate matter (PM 2.5) have decreased 55 percent since 2005, while nitrogen dioxide levels have fallen 50 percent."

Whale pee = fertilizer During warmer months, whales feed in nutrient-rich polar regions. When they migrate to mate and reproduce in warm tropical waters, their urine is high in nitrogen and organic matter, which is dispersed among areas typically low in nutrients. See:

New international agreement to cut emissions from shipping www.carbonbrief.org/qa-nations-a...

International Maritime Organization estimates at least $11 billion in revenue annually, with the money to be put into a net zero fund to invest in fuels and technologies needed to transition to green shipping, reward low-emission ships and support developing countries. apnews.com/article/ship...

High drama at the International Maritime Organisation, as a set of policies to drive the shipping sector to net-zero goes to a vote. A set of countries including Saudi Arabia 🇸🇦 and Russia 🇷🇺oppose the deal. Pacific island nations, who have been pushing for more ambition all week, chose to abstain.
