Could the plant breeding achievements of the Green Revolution be started again from scratch? That's the hope of scientists at the John Innes Centre, who say modern commercial varieties of wheat used by farmers could be replaced with better ones, using wheat lines collected a century ago. Back in the 1920s, an enterprising plant scientist named Arthur Earnest Watkins sent out letters to other Brits around the world, asking them to collect locally grown wheat, hoping the traits in those local cultivars would come in useful in the future. That original Watkins Collection is now based at the John Innes Centre in Norwich - but a massive 60 percent of the genetic diversity held within it, has never been looked at.
The Landworkers' Alliance is one of the smaller groups. It speaks for regenerative and sustainable agriculture, but with an emphasis on local production, and getting more people involved in growing food. We hear what they want from the next Government.
And we visit a new "Centre of Excellence" in glasshouse growing at Hadlow College. It's been set up with Thanet Earth - the biggest greenhouse complex in the UK, growing salad veg.

A recent E-coli outbreak is thought to have been caused by contaminated salad leaves. There have been over 200 confirmed cases of food poisoning across the UK caused by e-coli bacteria found in manure, with nearly half those affected admitted to hospital. So how does the bacteria get into the salad, and what are farmers doing to prevent it?
As part of our week looking at salads, we visit Evesham Vale Growers in Worcestershire, where they grow 500 acres of spring onions outside and some 70 acres of premium tomatoes in glasshouses. Alongside salad production, they grow crops including maize and wheat to feed anaerobic digesters for gas and electricity, and there's a solar farm. Some of the gas and electricity is used to heat and light the glasshouses - insulating them somewhat from fluctuating energy prices.
The Soil Association, which campaigns for sustainable and organic food and farming, has published it's list of demands in the run up to the election. It wants the next Government to 'grow green jobs' by backing sustainable British farming and protect the NHS by supporting healthy and sustainable food.

With the rain continuing and below average temperatures, the outlook isn't so sunny for UK salad growers.
We look at some of the detail in the main parties' manifestos to see what they're promising on issues like the agriculture budget, food security and England's badger cull.
Sometimes described as a farmer's best friend, dung beetles consume, bury and break up dung, improving soils as they go. Earlier this month vets and farmers met at a conference in Somerset devoted to the dung beetle.

Three UK vet practices are now offering IVF for cows. It's a common practise for dairy cows to be made pregnant using artificial insemination, but IVF is more specialist. It allows for multiple embryos to be produced from one particularly good cow, meaning the genetics of a herd can be improved more quickly and its health and productivity improved. But it means hormonal treatments and some invasive procedures for the cow - so is it ethical?
In a world first, methane from slurry on a farm in Somerset is being broken down and turned into hydrogen gas and graphene. Graphene is a material that was discovered in the UK 20 years ago, and is normally made from mining graphite rock. But a company called Levidian has developed a process which separates the carbon and hydrogen in methane gas, to make graphene and hydrogen.
And ten police forces across the country will soon be trialling new forensic technology to help identify dogs involved in livestock attacks. We hear from farmers affected and find out why the police think this new kit will help.

The vets using IVF to improve dairy herds, and could a new 2-stage planning system help kickstart the rural economy? We hear from the CLA on what it wants from the next government.
In a special episode of On Your Farm recorded at the Hay Festival, Kate Humble explains how she accidentally ended up buying a council farm in the beautiful Wye Valley in Wales.
