Welcome to mastodon everyone! I love seeing all this art posted. But we do have some folks on here who don't see well, and they really appreciate it if you add a description to your images. Just briefly what you're showing people, so that they have some idea what they're looking for.
I know sometimes it seems like too much work, and if you can't you can't. But it does make your work accessible to more people, not least because more of us will boost it.
If you find your mastodon experience too political, too meme-y, too science-y, or just not interesting enough, choose who to follow more carefully. Unfollow some people who fill your timeline with boring stuff; it's not a personal judgement, and you'll still see it if one of your friends boosts their toot. And follow someone who posts the sort of thing you like. Check out hashtags from their cool posts.
Most of all, post the sort of thing you'd like to see more of!
@anne @Maltimore @puffinus_puffinus @InvaderXan One of the reasons for crop rotations is to try and counter this issue. Some plants add nitrogen, others use up lots, etc, so by rotating crops, the soil doesn't get depleted.
Though you need to add manure as well as rotate crops. Here I would add green manures or farmyard manure, rather than any fertilizer that comes from fossil fuels.
Can a nonbinary boy participate in #wenbiesday ? Either way I thought I rocked this goth disaster look yesterday (I got lots of disapproving looks in the library so I'll mark that down as a win)
PSA! Finding work for my friend who's a nutritionist/personal trainer. Please read because there's a lot to this :D Also please share! <3
My friend Jen has fibro, IC, depression, and anxiety. Two years ago she was hugely overweight and unfit, and walking ~100m was enough exertion that she'd feel sick afterwards. Today, she's lost 80kg in weight and is a qualified personal trainer and nutritionist. She does Krav, boxing, runs a community social walking group, teaches teens self-defense. (1/?)
Even monoculture farms need to sometimes give fields a fallow year, to let nature sort things out. Other farmers plant beans to enrich the soil with nitrogen.
They usually don't even harvest the beans, annoyingly. When I was a kid, I used to go and "acquire" lots of them from nearby fields. It's not like they'd be missed!
However, it is true that plants are mostly made of cellulose and lignin. These are the biopolymers which make up all their structures, and which we process into paper. And those are built, essentially, from sugar. Plants get sugar from photosynthesis – they convert CO2 into sugar to store it and/or use it.
So a significant amount of any plant was indeed once atmospheric carbon dioxide – or, more simply, air.

As for nitrogen, it's more than just a catalyst. In plants, it's an integral component of the molecular structure of chlorophyll. See this image. The N is nitrogen. Note also the magnesium (Mg) atom in the centre!
All life on Earth also needs nitrogen to build proteins. Plants usually just build as many proteins as they can, so lots of nitrogen and lots of light makes plants grow faster. Nitrogen is also fixed from the atmosphere by soil bacteria. Some plants (notably legumes) cultivate these bacteria symbiotically in their root nodules.
On Earth, metals get passed around from one form to another. Plants (and animals) need bioavailable sources, which usually means salts. As well as potassium, plants need many other minerals. Manganese and magnesium, for instance, are essential for chlorophyll to function. Mostly, plants get these from ground water, which usually contains enough dissolved minerals to meet their needs.
Growing Saffron (critters/predation)
Not much decides to predate/nibble on #Saffron but if you have deer or rabbits, they can kill the crop by eating off the leaves in winter. I hear if you have rats in your garden, they might actually dig up and eat a corm.
The only thing I've ever seen in my garden is some nibbling by squirrels on the flower petals during the harvest, and it pretty much looks like the below. My wire cover is loose with gaps and this fresh nibbling probably took place last night.
Growing Saffron (emerging blooms)
Here is an emerging #Saffron shot, where you can see the flowers starting to come out of the corm tips. The layers spiral a bit, and the flower moves right up the center.
Two blooms are emerging here, and if the sun comes out and the flowers warm up enough, they will open fully.
Growing Saffron (1st flower!)
Deity in the house! Welcome, #Saffron!
Here is the first flower to appear. Unless you take the time and effort to grow saffron, or intentionally research it, most people never have an opportunity to see the flowers.
I will let this flower stay for a couple more hours, and actually open, so I can take some pictures.
