The 88th annual National Ploughing Championships get underway in Fenagh in Co Carlow this morning.
Up to 300,000 people are expected to attend the event over the next three days.
The event in Ballintrane, Fenagh will be officially opened by President Michael D Higgins today.
Sheep shearing, fashion shows, vintage ploughing, baking competitions and craft demonstrations are among the events taking place over the next three days.
All sectors of the food chain are represented from farmers to artisan food producers, craft beer makers and celebrity chefs.
Organisers have pledged to 'go green' this year.
No waste from the event will end up in landfill, food waste will be converted into electricity and caterers will use compostable materials for single-use items 'as much as possible'.
There will also be a 50 cent ‘reusable cup discount’ on all teas and coffees.
Love Island winner Greg O'Shea is due to take part in 'special dating contest' Grá Island, which is being hosted by the National Dairy Council.
Leaders and representatives from most of the major political parties are also expected to attend over the coming days.
Exhibitors, global buyers and visitors from more than a dozen countries - including the USA, India, Ghana and New Zealand - are expected at the site over the next few days.
This year's event takes place against the backdrop of the ongoing beef dispute, which has seen farmers blockade meat processors around the country in the row over prices.
