Description

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, 4. Turn the oven on, 5. 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 soil350(1), pp.71-84.

Unfortunately, once again, it's behind a paywall. Sorry about that. I only realised at the last minute. We are still looking for an open access version and we will post a link if we find one. 

This is where we think Karin works now (based on our expertise in internet stalking of scientists). 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
