Tillage: The benefits of grain analysis at harvest
It also aids the planning of crop nutrition strategies for the season ahead.
These issues were discussed in detail at a recent webinar hosted by ADAS, under the aegis of its Nutri-Check programme.
According to ADAS associate managing director and crop physiologist, Dr. Sarah Kendall, the principles involved in developing a future crop management strategy are: plan, check, and adjust.
She explained: 'Nutri-Check is a Europe-wide project, within which ADAS is taking the lead.
'Courtesy of the work carried out already, we have identified the need to provide better support to farmers and advisers.
Dr. Kendall said this support will enable farmers to make better crop nutrition decisions.
'To help facilitate this, we have developed a framework, which we call the three step checking approach.'
'This comprises three key elements, which are: planning, making checks and adjustments while also reviewing the decisions that have been taken,' Dr. Kendall said.
The ADAS representative went on to point out that while farmers are generally good at determining the nutrient requirements of their crops through the creation of a plan, they rarely check and adjust the initial recommendations that were made.
She said: 'It's only very recently that we have found out how analysis at harvest can determine how crop management decisions have actually worked out.
'On most farms, the success of nutrient applications is determined by final yields, irrespective of the fact that many non-nutritional factors impact on final performance.
'We also know that nutrient concentrations of harvested produce show if the crop has captured insufficient, adequate, or excessive amounts of each nutrient.'
Dr. Kendall highlighted that really getting to grips with such information allows farmers to revise and review issues such as nutritional performance, soil nutrient balances, and efficiencies of nutrient application.
She said: 'This is really important in terms of informing future nutrient management on a crop-by-crop basis.
'End of season review is vitally important in terms of what factors had impacted on the previous crops and while providing a number of amendments, which can feed into the following season's planning.
'This is a continuous cycle of moving from a plan to check and adjust and then review.
'And all of this feeds into a future planning process.'

Dublin Lidl store forced to close after rodent droppings and mouse spotted
A Lidl supermarket in Sallynoggin, Co Dublin was served with a closure order in July by the Food Safety Authority of Ireland (FSAI) after rodent droppings were found in 'multiple areas' and a mouse was seen running across the floor of the storeroom. The authority said the rodent activity posed 'a grave and immediate danger to food safety'. It was one of 10 enforcement orders issued by the FSAI in July, described by its boss as 'serious, preventable breaches of food safety law'. The store's closure order, issued on July 29th, was lifted on August 1st. READ MORE Rodent droppings were found on the Lidl shop floor behind a food display unit, at the side of a freezer also on the shop floor, and in the storeroom according to the inspector's report in July. 'Extensive food debris is evident on the floor of the storeroom, on the shop floor and on the floor of the bakery. The shop floor and bakery floor have not been cleaned and sanitised,' the report said. 'Adequate procedures are clearly not in place to control pests in the premises. A live mouse was observed running across the floor adjacent to the baler in the storeroom, by two environmental health officers.' Meanwhile, the Brandon Hotel in Tralee, Co Kerry was forced to close all kitchen areas and the restaurant after 'significant cockroach infestation' was found throughout the food premises and live cockroaches were observed in the restaurant. Dead cockroaches were found in the main kitchen under work surfaces and cooking equipment where food is prepared and cooked, under service fridges, under shelves where dry food is stored, on the floor in the wash-up area and of the staff canteen. 'Alive cockroaches were observed in the restaurant,' it added. The closure order issued on July 23rd was lifted on July 25th. [ Ireland What is your experience of ready-meals from Irish supermarkets?

Photograph: Getty Images At Costa Coffee, on Dawson Street in Dublin, rat droppings were found in the dishwasher room and the food store, and at the main customer entrance. The inspector's report noted: 'A gap at the bottom of the main customer door could allow pests such as rats to enter your food business.' The closure order issued on July 2nd was lifted on July 4th. Emerald Park in Ashbourne, Co Meath was also forced to close a storage unit at the rear of a coffee dock when rat droppings were found in an area to store food such as candyfloss and re-usable cups, lids, straws, food containers and trays. 'The unit was not pest proof with holes noted in the walls,' the inspector's report stated. The closure order issued on July 14th, was lifted on July 15th. Creed's Foodstore, Cahir, Co Tipperary ; Londis Connaught Street, Athboy, Co Meath; and KRS Catering Stall, Clonmel, Co Tipperary were also served with closure enforcement orders which have since been lifted. Hidden Dojo Asian Street food and Wakami Sushi & Asian, both on Phibsborough Road in Dublin, were also served with closure orders. [ Ireland FSAI recalls spinach and mixed leaves products over listeriosis fears Opens in new window ] Ballymaguire Foods Unlimited Company, Rathmooney, Lusk, Co Dublin which was at the centre of the controversy over the detection of Listeria monocytogenes and which was granted approval to re-start production, was served with a prohibition order on July 18th on pre-packaged turkey and ham dinners. Tim Nessa, on John's Street, Limerick, was served with a closure order on July 8th, but the FSAI sought and was granted an interim High Court prohibition order when the premises continued to trade. Greg Dempsey, chief executive of the FSAI, said 'recent foodborne incidents serve as a stark reminder of the need for food businesses to maintain the highest food safety standards'. 'Consumers are entitled to expect that the food they purchase is safe, and food businesses have a clear legal and moral responsibility to ensure that it is. The enforcement orders issued this month reflect serious, preventable breaches of food safety law,' he said. He added that the FSAI could provide support and advice to food businesses to help them meet their obligations. 'However, as demonstrated by the enforcement actions this month, where food businesses do not comply with their obligations, we will take action,' he said.

‘Don't underestimate this guy': Who is Gareth Sheridan, the pharma millionaire running for president?
Gareth Sheridan is, in one respect, the face of the impact of Donald Trump's tariffs. The share price of Nutriband, the business he cofounded in 2012, has dropped by almost 10 per cent in the past month, affected by the US tariffs uncertainty. For the year to date, it's still up by 57 per cent and the pharma company has a market value of $80 million (€69 million) – it was valued at $100 million in January. Nutriband has yet to generate any revenue and is awaiting US Food and Drug Administration (FDA) approval for its technology, which is designed to prevent abuse of patch medications. Sheridan has talked about the technology in the second quarter of next year, if not before, subject to FDA approval. READ MORE Sheridan wants to be the next president of Ireland, having announced his plans to seek the nomination through local councils. He needs the support of four local authorities to get on the ballot paper. The 35-year-old, from Terenure, south Dublin, lacks the support from the Oireachtas of Mairéad McGuinness or Catherine Connolly , or the name recognition of Michael Flatley or Conor McGregor , both of whom have indicated interest in running for the office. As an unaffiliated unknown, the road to Áras an Uachtaráin looks to be a long one for the entrepreneur. The challenge gets tougher when you consider that Seán Gallagher's second-place finish in 2011, with 28.5 per cent of first preference votes, is the best performance by any candidate to go the council route in the election. Gallagher, as it happens, is executive chairman of Nutriband. [ Pharma businessman Gareth Sheridan enters presidential race as Independents compete for nominations ] The Technological University Dublin (TU Dublin) graduate's lack of name recognition or party support means that even getting on the ballot is a daunting prospect. It's one that he has likely prepared for, says Dr Siobhán Killion, head of management at TU Dublin's school of management, people, and organisations. 'Don't underestimate this guy,' Killion says. 'I mentioned his name to a few people on Sunday. They didn't have a clue who he was. His biggest obstacle is to become known, but he's no fool and he'll rise to the challenge. There'll be very few people in Ireland come November that won't have heard of him. 'He's such a busy guy, but it doesn't surprise me. He seems to be the king of time management. He's very much on top of his game.' Sheridan did his undergraduate degree at TU Dublin while in the process of establishing Nutriband. 'It was at the expense of my grades,' he told The Irish Times in February. 'My dad wears a patch for heart medication. I figured patch technology could be expanded. As I wrote my thesis, it felt more like a business plan,' he says. Killion got to know him at TU Dublin. 'He knows how to juggle commitments. His ability to keep all the balls in the air successfully is something he's got in spades,' she says. 'He was the guy that didn't attend classes because he was working on his business idea. That's okay because not everybody's academic journey is the same. He did what he needed to do to get where he needed to be.' Killion has stayed in contact with Sheridan since, inviting him back to speak to students in TU Dublin. 'Gareth, being an alum of TU Dublin, has freely given his time to encourage entrepreneurship among our students. Any time I've reached out to him, he's come back without hesitation to help,' she says. 'He's a great mentor to students. These are undergrads, your typical 20-year-olds, and he's in there with them advising and encouraging them.' In February, Sheridan said his goal was to 'put manners' on the largest pharmaceutical companies in the US. Nutriband has developed a system to change the way patches of painkillers such as fentanyl and other opiates work. The aim is to reduce abuse and prevent risk of accidental exposure. 'They're competitors. We're coming in aggressively and to put manners on an industry that has ignored a major issue for a long time. I am baffled that the industry has let prescription rates drop so much without attempting a fix,' he said at the time. The route to getting the business off the ground and on to the Nasdaq stock exchange in New York involved Sheridan working in food delivery and other gig economy roles to keep the company functioning while awaiting approval to get listed. The company is based in Orlando, Florida, and he has resided in Salt Lake City, Utah, his wife's home city, but is in the process of moving back to Dublin. Sheridan documented his journey in his autobiography, From No to Nasdaq, which came out earlier this year. The bullish approach came as no surprise to Aonghus Shortt, cofounder of FoodMarble. Shortt's company is working on gut health, having raised €8 million to date. He met Sheridan in 2022. 'He approached me via LinkedIn. He was listed on Nasdaq [in 2021] and for a company that size it was somewhat unprecedented among Irish start-ups. I'm sure one million people told him it was a horrible idea, but he made it work,' Shortt says. 'When we met up, he was encouraging me to consider listing. We didn't, but I was impressed he did. He's a very confident guy and an independent thinker. I found him quite impressive.' Sheridan is stepping back from his role with Nutriband, where he owns 18 per cent of the business, during his presidential run. Were he to win, he would have to remain detached from the company. His co-founder, Serguei Melnik, is taking charge in his absence. 'He [Sheridan] seems nice and transparent, but what he did [with Nutriband] was audacious. It's weathered some storms,' Shortt says. 'It's another audacious move. It's not a very big company or stock, so it's not like all eyes in the US will be on what he does, but you can imagine some shareholders might be wondering why he's doing this.' Sheridan is one of 24 finalists chosen to compete for the title of EY Entrepreneur of the Year awards. He has been chosen along with seven others in the established category. The winner of that category would then vie with the two other category winners (emerging and international) for the overall title. One of Nutriband's shareholders is Jim Breen. The PulseLearning founder met Sheridan on an EY Entrepreneur of the Year CEO retreat to Japan earlier this year. Breen was a nominee in 2007. 'There were around 140 of us in Japan for a week. It was my first time meeting him. He's got a special kind of mentality that mixes humility with confidence. He's a learner, but he's also experienced. The part that impressed me most was that he's had knock-backs, but has resilience about him,' Breen says. Having invested in the company based on that meeting in Japan, Breen acknowledges that it is less than optimal to have Sheridan stepping away from the business for a run at the Áras. 'It's not ideal from an investor perspective. However, he's got the thing well thought through. A Nasdaq-listed company has a team of people in place, it doesn't depend on just one person,' Breen says. 'With some things in business and life, you just work them out.' A spokesman for Sheridan told The Irish Times that he 'holds dual citizenship' for the US and Ireland. A statement said: 'As regards holding or contesting for the office of president of Ireland there are clear precedents regarding Ireland-USA dual citizenship holders. 'In 1959, Éamon de Valera , a USA citizen (by birth), was nominated and elected president of Ireland.' On Newstalk on Monday Sheridan denied he had renounced allegiance to Ireland as the oath on taking up US citizenship requires. Queried by The Irish Times, his spokesman acknowledged that 'as tens of thousands of Irish people before him faced with the choice of being undocumented or 'legal' in the US, Gareth Sheridan was 'naturalised', taking dual citizenship, he pledged allegiance to the USA. That to him meant allegiance while resident in the US, albeit involving renouncing his allegiance to any other 'power'. 'However, he and all Irish people of dual citizenship with the USA continue to be Irish citizens. While residing in the US for seven years he retained and used his Irish passport. He and his family are now legal residents of Ireland.' Perhaps there is an echo of de Valera's 'empty formula' taking the oath of allegiance on entering the Dáil in 1926. But otherwise, following in de Valera's footsteps appears a long shot. He first needs to get himself on the ballot paper, which will be challenging in itself. But Sheridan has never lacked ambition in business and he will seek to apply his skills as an entrepreneur to the political arena. Additional reporting by Pat Leahy

Black market weight-loss drugs ‘not worth the risk', warn pharmacists
Counterfeit weight-loss products sold online 'pose serious risks to an individual's health', the Irish Pharmacy Union (IPU) has warned. The union is urging the public to think twice before purchasing medicines from unverified websites due to the potential for 'serious risks' to health. The Health Products Regulatory Authority (HPRA) seized 7,815 counterfeit weight loss drugs in the month of May. This was almost five times the 1,582 seized in all of 2024, which itself was a jump from 568 in 2023. Purchasing these products 'is not worth the risk', said Tom Murray, president of the IPU, which is the representative body for more than 1,900 community pharmacies in Ireland. READ MORE 'There are no safety checks, no oversight, and no guarantees about what is actually in the medicines,' he said. The IPU also said people may purchase fake products out of a belief they are cheaper and that it was easier to avail of them through bypassing healthcare professionals, the IPU said. Legal prescriptions for genuine weight loss drugs Wegovy and Ozempic from Novo Nordisk , and Eli Lilly's Mounjaro can cost users about €220 per month. They are not currently included in the HSE's Drug Payment Scheme, which limits monthly medicine costs to €80. They are also not available free to medical card holders in Ireland as a treatment for obesity. Ireland has one of the highest obesity levels in Europe, with some 60 per cent of adults classified as overweight or obese. Nearly a third of people go to the internet for health information, according to a recent study commissioned by the IPU. 'Online consultations have improved healthcare access, but purchasing medicines from unregulated websites is a potential disaster waiting to happen', said Mr Murray. 'There is no way of knowing if [the drugs] meet the appropriate standards, whether they have the correct active ingredients or contain harmful substances. You could be taking something completely ineffective or dangerously toxic,' Murray added. 'If the medicine you purchase is not from a registered pharmacy, do not take it', said Murray.
