29/04/26 Giant greenhouse, silvohorticulture, Scottish election

Farmers are hoping for more rain in May after an unusually dry and windy April in many part of the UK. The East of England had between 2 and 4 per cent of the expected rainfall last month. We hear from a farmer struggling to plant his crops. This week we look at agroforestry - that's farming with trees in the mix. We visit farms using trees for different reasons - including providing shade for livestock, adding nutrients to soil, and providing habitats for useful insect predators. And the UK's second largest greenhouse - which could replace 7 per cent of the tomatoes the UK imports - has been given the go ahead. Rivenhall Greenhouse near Braintree in Essex will cover 40 hectares and use power from a domestic waste incinerator - burning all the black bag waste from the county.

Farmers are hoping that a dry April will be followed by a wet few weeks. Some parts of the country, notably in the East of England, have had between 2% and 4% of the expected rainfall last month. This feels a lot like last year when the dry spring led to a loss of yields and even failed crops and that hit the bottom lines of farming businesses. Some farmers are warning that without rain soon we could see the same again this year.Less than a week to go now before elections across the UK. We've talked about the issues rural voters in Wales and Scotland are considering as they vote for their national governments who control agricultural policy, today we're turning our attention to the council elections in England. We've been talking all week about agro-forestry: planting trees alongside crops or livestock grazing. Today we hear how hedgerows can benefit farms.Presented by Charlotte Smith and produced by Beatrice Fenton.

Mixing trees and farming in agro-forestry: why the key to resilient farming could be trees. We're looking at this all this week and today we hear from a British pioneer. A week today millions of people will head to the polls to vote in a number of local council and mayoral elections in England, while voters in Scotland and Wales will elect representatives to their national parliaments.  Farming policy is largely devolved to the governments in Edinburgh and Cardiff, and having heard the latest from the campaign trail in Scotland yesterday, today we turn to Wales.This Sunday is International Dawn Chorus day. The RSPB is using the occasion to celebrate a rise in the number of young people bird watching, though the British Trust for Ornithology warns that there are fewer birds for them to see and hear.

A 40 hectare greenhouse has been given the go-ahead in Essex. It'll be the UK's second largest, and will be powered and heated by a domestic waste incinerator on the same site. The company says it will grow 28,000 tonnes of tomatoes a year, which will offset 7 percent of UK tomato imports from Southern Spain, Morocco and Holland. We visit a farm in Gloucestershire where they incorporate trees into everything they grow. Silvohorticulture uses the trees to provide shade, wind cover, and compost. And this week we're looking ahead to the upcoming elections in the UK. Today, what politicians are promising farmers in Scotland. Presented by Anna Hill and produced by Sally Challoner.

A new collaboration has been set up between scientists and the fishing industry in Cornwall, to integrate scientific research with the real experience of fishers. Assessing current fish stocks and how not to damage them, has often been a point of contention between the two, but now it's hoped that the Cornwall Fisheries Science Board will lead the way for a similar approach nationwide.All week we're taking a closer look at agro-forestry, today we visit a farm in Shropshire which has created silvo-pasture - growing trees on the pasture used by livestock. Tim Downes says the health of his 300 organic dairy cows has improved, since he planted willow trees and walnuts.Some potato farmers are struggling to find a market for their crop, one grower in Cambridgeshire is donating tonnes of spuds he can't sell to a food bank. It seems there is an over-supply of potatoes after a very successful growing season last year. It's not just in the UK but across Europe too. As war in the Middle East pushes up the cost of fuel, fertiliser and energy, will farmers bother planting potatoes this spring?Presenter = Anna Hill Producer = Rebecca Rooney

A landmark legal case over water pollution gets underway later today. Thousands of people are part of the case which claims that chicken farming and sewage spills are causing pollution in three rivers, the Wye, Usk and Lugg. The case against chicken producers Avara and Freemans of Newent, and Welsh Water, will be heard at the High Court in London. All three firms vigorously deny the claims.A new report from MPs highlights low morale and a lack of trust in officials amongst fishing communities. All week we'll be looking at agroforestry, or farming with trees in the mix: putting pigs into an orchard or planting fruit trees in an arable field to provide wind breaks and food.

A new trial is starting this summer, as part of a programme to develop a vaccine for people against bird flu. 3000 volunteers are needed from the UK to take part, and 1000 in the USA. Researchers at the National Institute for Health and Care Research are hoping that poultry workers might take part.A new report warns that UK farming's reliance on imported fertiliser and minerals, puts it at risk in times of geopolitical stress. Analysis, published by the National Preparedness Commission, highlights the fragility of global supply chains on which UK agriculture depends.Fuel and fertiliser costs are soaring because of disruption caused by the war in the Middle East. That's having a big impact on farmers and it's also putting pressure on food prices as MPs on the Environment Food and Rural Affairs select committee have been hearing. They were told that food prices were 40% higher than before Covid and that the food supply chain needed urgent government support with fuel costs.We visit a field trial of a gene-edited barley which contains higher levels of fat. Scientists believe this will make it a more efficient livestock feed, and could also reduce methane emissions by making it more digestible.Thatching is becoming more of a challenge due to issues with some of the materials. Supplies of the right sort of wheat straw can be unpredictable and the hazel spars used to attach the thatch to the roof now have to be imported from Eastern Europe. To kick start interest in growing more locally a ‘summit’ of thatchers, farmers and plant scientists was held this week in Suffolk.Presenter = Charlotte Smith Producer = Rebecca Rooney

Whilst the cost of producing a crop is up, particularly the cost of fuel and fertiliser, the price paid for it hasn't risen by anything like as much. If the situation stays the same by the autumn some farmers may decide not to grow loss-making crops, leaving fields lying fallow. There are calls for the Government to fund a one-off a scheme to protect this land from soil erosion by planting cover crops, and these could also reduce the use of fertiliser. The idea comes from the Central Association of Agricultural Valuers, the professional body for farm valuers and advisors.Thatching is becoming more of a challenge due to issues with some of the materials.

A new report warns that UK farming's reliance on imported fertiliser and minerals, puts it at risk in times of geopolitical stress. Analysis, published by the National Preparedness Commission, highlights the fragility of global supply chains on which UK agriculture depends. All week we've been looking at ideas for cutting emissions on the farm. Today we join Stuart Oates, a 7th generation farmer on The Lizard Peninsula in Cornwall. He set himself a long term aim: to remove single-use plastics on the farm and end his family’s reliance on fossil fuels.  Towards that goal, he’s taken up a Nuffield scholarship, travelling the world to see if the UK can learn from innovations elsewhere, to reduce emissions.  We also hear from an organisation which helps farmers recycle their plastic waste.

One of the biggest growers in the Vale of Evesham in Worcestershire says it’s making its crop-growing more environmentally friendly by developing a giant one hectare high-tech greenhouse. The company says it’s drastically reduced crop spoilage, fertiliser and water use, while also making the UK less reliant on imports. Presenter = Anna Hill Producer = Rebecca Rooney
