Welcome to this occasionally mildly interesting farming podcast (it's a science podcast), hosted by award winning podcaster Michael Blanche (200m swimming badge 1978) and not-yet-not-a-real-doctor Paul Allison. We talk about recent research into soil, pasture, cows and sheep. People say that it's the podcast they didn't know they wanted or needed, and they definitely didn't ask for it. It's sometimes a bit sweary (not the big one). It's fine. Cows and effect sounds like cause and effect. It's a play on words. That's funny stuff. Warning: Following legal advice the listener should be aware that the views and information shared in this podcast do not constitute professional advice or even unprofessional guidance. For God's sake consult someone who knows what they are talking about before making any changes to your farm management practices.

    Howdy, yee-haw and yippee-ki-yay buckaroos. Get your ears on, because we're headed west of the Pecos for the rootin' tootin' episode 3. of Lab Rat Jazz Club, where things are fixing to get plumb loco down in the lab. Hot-diggerty-dawg. As usual, there's the odd cuss word, but not the big one.

    Here's the link to the paper, but listen first and read after. Link to Dr Eren's fine research paper. Here is a link to the Supplementary Data, which has all the photographs in it. It's true, they actually did it.

    Email questions, comments, suggestions and Michael Blanche fan mail to cowsandeffectpodcast@gmail.com. You should probably open with; "Dear Michael, loving the show; oh my goodness, you are so fab (etc, etc.)"

    We really can't be arsed with the admin for social media or fending off all the inevitable and well deserved online abuse, so help us out listener. In the unlikely event that you 1. enjoy the podcast and 2. don't mind people finding out that you enjoy the podcast; then tell your friends. You know the drill by now; "Have you heard about Cows and Effect? It's a farming podcast with the charming, handsome and and brilliant Michael Blanche. You know, the guy from The Pasture Pod and that time thing. He's amazing. I love him. There's another one, but I've forgotten his name. It doesn't matter; did I say it's got Michael Blanche in it?"

    Somehow, we keep coming back to polar explorers and we finally got around to Scott. Links to short films about Scott's last expedition.

    Happy New Year listener. Eight episodes in (hard to believe for many reasons) and it's a bit different this month. There's absolutely no big swears; there's a few mediums, but not the big one. And also because we talk about lots of research papers addressing two subjects; small cows and short tails in sheep. Listeners to Michael's "exceptional value" Pasture Pod Patreon channel will have heard about these slightly niche topics before. Do smaller cows cause less damage to soil in pastures than heavier cows? Are the intakes of cows proportional to their weight? If you breed for short tails in sheep, will you impact lamb weights and spine lengths? These are the questions that keep Michael awake at night. We have an email address listener. It's cowsandeffectpodcast@gmail.com Please email your questions for the authors of the papers that we have discussed. Subject to the restraining orders, we'll try to get them lined up for Episode 12. Feel free to email in with any other questions or suggestions. Please start your emails with this phrase, "Dear Michael, loving the show. You are my favourite. It's only a shame that the other one keeps interupting you. You're the best. I love you. Oh my goodness, you're so handsome." Michael doesn't read the show notes so it will be a lovely surprise for him and make everybody else's life that bit easier. See the Episode 7. shownotes for how to get in touch with Karin.

    Episode 7. Folk dancing, pocket meat and the Malmo shipyards.
    Dec 25 2025

    This festive episode comes out on 25th December 2025, so Happy blooming Christmas listener. If you're anything like me, the morning so far will have been; 1. Put the turkey in the oven around 06.00 hrs; 2. Check round the stock, 3. Get back to the house in time for a late morning snifter, 4. Check how the turkey is doing, 5. Turn the oven on, 6. Explain that Chistmas dinner is running late.

    There's some robust swearing in this one listener, including the big swear at around nineteen minutes in. Sorry about that. We know a lot of people don't like the big one, but think it's canonically justified in this case. We'll try to avoid it in the future.

    The original recording included my favourite ever Christmas joke, but Michael cut it out and burned the tape. I thought it was funny, but he explained that being funny isn't always enough to avoid being taken off air. We have exchanged Christmas presents. I don't understand why I received a £50 voucher for therapy, but Michael says that me not understanding that there is a problem is "just another symptom". Micheal has only very recently realised why he received a dictionary with the word "canonically" underlined.

    As promised, this month we're in Denmark and looking at Nitrogen transfers from legumes into grasses and herbs. Which legumes are good at fixing? Which are good at transfering Nitrogen to neighbouring plants? Which non legumes are good at acquiring the Nitrogen? Only one way to find out the answers listener.

    Actually, there is another way. If you just read the paper, you don't have to listen to the chaos and the big swear. Here it is. Pirhofer-Walzl, K., Rasmussen, J., Høgh-Jensen, H., Eriksen, J., Søegaard, K. and Rasmussen, J., 2012. Nitrogen transfer from forage legumes to nine neighbouring plants in a multi-species grassland. Plant and soil, 350(1), pp.71-84. Nitrogen transfer from forage legumes to nine neighbouring plants in a multi-species grassland | Plant and Soil

    Unfortunately, once again, it's behind a paywall. Sorry about that. I only realised at the last minute. Karin has very very kindly messaged us to say that if you want a copy of the full paper, she will send you one. You will need to email her on pirhofer@weltacker-berlin.de to request a copy.

    Our expertise in internet stalking of scientists revealed that this is where Karin works now. It's Weltacker Berlin and they all look like they are having fun. Weltacker Berlin | Weltacker . Weltacker is a global agroecology demonstration and education organisation (the Berlin site was the first). They are not for profit (which definitely aligns them with our sort of farming). Check it out. Welcome to 2000m2 .
