As urban populations boom, urban agriculture is increasingly looked to as a local food source and a way to help combat inequitable food access. But little is known about how productive urban agriculture is compared to conventional, rural farming. A new study digs in, finding urban gardeners and hydroponics can meet and sometimes exceed the yields of rural farms. “Despite its growing popularity, there’s still quite a lot we don’t know about urban agriculture, like whether the yields are similar to conventional agriculture, or even what crops are commonly grown,” says Florian Payen, an environmental scientist at Lancaster University and lead author of the study, published today in AGU’s journal Earth’s Future. The new study compiles studies on urban agriculture from 53 countries to find out which crops grow well in cities, what growing methods are most effective, and what spaces can be utilized for growing. The researchers find that urban yields for some crops, like cucumbers, tubers and lettuces, are two to four times higher than conventional farming. Many other urban crops studied are produced at similar or higher rates than in rural settings. Cost efficiency remains an open but important question. Most studies on urban agriculture have focused on green spaces, such as private and community gardens, parks and field growing operations. Payen’s work includes “gray” spaces — places in cities that are already built but could be used for growing, such as rooftops and building facades. In both green and gray spaces, the study examines a suite of crops grown in soils versus hydroponics, horizontal versus vertical farming, and natural versus controlled conditions. “Surprisingly, there were few differences between overall yields in indoor spaces and outdoor green spaces, but there were clear differences in the suitability of crop types to different gray spaces,” Payen says. Certain crops like lettuces, kale and broccoli are more naturally suited to be grown vertically in indoor spaces than others. “You can’t exactly stack up apple trees in a five- or ten-layer high growth chamber,” he says, “though we did find one study that managed to grow wheat stacked up like that.” Other crops, like watery vegetables (e.g., tomatoes) and leafy greens, performed well in hydroponic environments. And crops grown in fully controlled environments can be grown throughout the year, allowing harvests to happen more times per year than in open-air environments, which leads to higher annual yields. But scientists will need to keep studying these systems to plan cost-effective agriculture solutions. The finding that urban agriculture can have similar or greater yields to conventional agriculture “is exactly what we have been waiting for in the urban agriculture research community,” says Erica Dorr, an environmental scientist at AgroParisTech who was not involved in the study.

Actually, I love that cottagecore has given Gen Z a word for "I want to have a big garden and cook my own food and keep chickens" that isn't casually invoking colonialism and manifest destiny. I get so goddamned uncomfortable every time someone refers to their urban hobby farm as a "homestead" and I'm glad to finally see it being replaced with other terms. I will buy a million books about how to live a cottagecore lifestyle if it will convince publishers to stop marketing the "homesteader" lifestyle and will get white city dwellers to stop unironically self-identifying as colonizers.

Good afternoon everyone~
It's cold, windy and it's been raining on and off all day but I finally got out to harvesting the sweet potatoes.
I started with the 'L' bed.
Tumblr media
This is the bowl I'll be using to collect the spuds for this deep raised bed.
Tumblr media
Those are full size scissors btw. This is the absolute biggest strainer I own and when I do harvesting I'm always glad to have it! Helps with carrying and washing off dirt outside so much easier!
Tumblr media
It was pretty fun digging round for the spuds and to be honest the size and shape of some of them really suprised me!
Tumblr media
For some size comparison, my hand is right on top of them.
Tumblr media
All cleaned out!
Next was the little round bed in the corner. I wasn't really expecting much, but it filled the bin pretty good.
Tumblr media
I've washed the spuds off and am letting them dry off but I'll be finding a spot inside soemwhere to let them sit and cure for a bit of time. (I probably will let them cure until end of febuary.)
Curing your sweet potatoes is what makes them sweet, you can eat them right away but their said to be bitter. (I will be trying 1 potato to see if this is true!) Curing them should be done for at least 2 week in a cool dry space (around 80*f). If you under 80*f space add 7 more days.
I thought this was neat and wanted to share it. since I've not seen a sweet potato grown or dug up before
Tumblr media
I wasn't expecting so much differance in spud size from one single root.
And one last pic,
Tumblr media
The ducks quite like the greens, while there's not much left of it I'm going to leave the vines a couple days so they can use it as enrichment/snack opportunity.
Weigh in on the spuds later!
🍠🌱Happy Homesteading and Harvesting!!

"In Washington D.C., a sophisticated sewage treatment plant is turning the capital’s waste into a form of capital: living capital that is fertilizing the gardens of farms of the Mid-Atlantic region and saving vast quantities of resources.
Described by the workers’ there as a “resource recovery plant,” D.C. Water run a biogas plant and high-quality fertilizer production in the course of their dirty duty to ensure the city’s waste finds a safe endpoint.
The nation’s capital is exceptional at producing waste from the toilet bowls of the 2.2 million people who live, work, and commute through the city and its suburbs.
Reporting by Lina Zeldovich reveals that rather than trucking it all to a landfill, D.C. Water extract an awful lot of value from the capital crap, by looking at it as a resource to send through the world’s largest advanced wastewater treatment plant, which uses a “thermal hydrolysis process” in which it is sterilized, broken down, and shipped off for processing into “Bloom,” a nitrogen-rich, slow-release fertilizer product. 
The other “Black Gold”
At their facility in southwest Washington, huge aeration tanks percolate the poo of everyone from tourists to the President. After it’s all fed into enormous pressure cookers where, under the gravity of six earth atmospheres and 300°F, the vast black sludge is rendered harmless.
Next this “Black Gold,” as Zeldovich described it, is pumped into massive bacterial-rich tanks where microbes breakdown large molecules like fats, proteins, and carbs into smaller components, shrinking the overall tonnage of sewage to 450 tons per day down from 1,100 at the start of the process.
This mass-micro-munching also produces methane, which when fed into an onsite turbine, generates a whopping 10 megawatts of green energy which can power 8,000 nearby homes. [Note: Natural gas (which is mostly methane) is definitely greener than coal and oil, but it still causes a significant amount of emissions and greenhouse gases.] The 450 tons of remaining waste from the D.C. feces are sent into another room where conveyor belts ring out excess fluid before feeding it through large rollers which squash it into small congregate chunks.
D.C. Water sends this to another company called Homestead Gardens for drying, aging, and packaging before it’s sold as Bloom.
“I grow everything with it, squashes, tomatoes, eggplants,” Bill Brower, one of the plant’s engineers, tells Zeldovich. “Everything grows great and tastes great,” he adds.
“And I’m not the only one who thinks so. We’ve heard from a lot of people that they’ve got the best response they’ve ever seen from the plants. Particularly with leafy greens because that nitrogen boost does well with leafy plants. And the plants seem to have fewer diseases and fewer pests around—probably because Bloom helps build healthy soils.”
While farms around the country are facing nutrient depletion in soils from over-farming, turning to synthetic fertilizers to make up the difference, introducing more such thermal hydrolysis plants could truly revolutionize the way humans look at their feces—as a way of restoring the country’s soils rather than polluting them. As Mike Rowe would say, it only takes a person who’s willing to get their hands dirty."

Quote
Urban food production in Havana and in Cuba is exceptional. Not only has it been reintroduced and supported by state institutions, but it is also integrated into wider agricultural planning, including peri-urban areas. This level of coordination is possible when the national state retains tenure over most land, private enterprise is restricted and profitability is subordinated to a primary directive of feeding people. Furthermore, the policies of the Cuban government over the previous decades have been crucial to establishing the research and extension structures, educational levels and skilling processes that became important in confronting the sudden economic downturn of the 1990s and promoting the development and implementation of technical innovations and improvements for urban farming. This is mainly through the above-described farmer-to-farmer movement coupled with specialised scientific institutes diffusing agroecological applications through ANAP. State institutions have played key roles in providing the inputs, material incentives and moral inducements (e.g. patriotism rhetoric) to diffuse agroecological and organic farming methods.

Alright, I don’t post much, but I have a question for some of you out there listening. I’m gardening out of my apartment & can’t use the dirt/backyard space because of lease agreement. What is y’all’s best recommendations for a raised bed/standing bed?

Ooooookaaaay Round 2! Transplanted all.of those morning glories that shot up into bigger pots.
Distributed Marigolds into Basil and tomato pots.
Got 8 cucumber shoots transplanted into their own pots.
Planted Hollyhock seeds and a varying variety of different tomato plants.
My craft room is over flowing!! I can't wait to get the greenhouse back up. Hopefully it will be done by April 15th!

~ Welcome to the August Garden~
Tumblr media
It is now the month of red! Look at this morning’s harvest.
My summer sown broccoli are looking so good. It’s my first attempt, so I’m very excited to see if we get any florets before the first frost.
Tumblr media
My first cabbage is also almost ready to be harvested and the tomatoes are giving us a steady stream of fruits now. Hopefully they will keep it up well into September.
Tumblr media Tumblr media
We are getting to the end of cucumber season. All that’s left of my plants are these little deformed ones, but I bet they will still be absolutely delicious!
Tumblr media
As for some color, my yellow nasturtiums have finally started blooming en masse. Next to them you can see that the marigolds are also still going strong 💪🏻
Tumblr media
Next month will probably look a lot more bare, as our first frost date is at the beginning of October.
Until next time,
~L

Kitchen post today~
With prices being what they are I like a good deal on groceries when I can find it. Sometimes that leads me to buying large quantities of things.
This week the local scratch n dent market had 5 pound bags of golden potatos on sale, 2 for $4. We like potatos so I snagged a few bags. Since i had 2 from last week's groceries I decided to pick through them all.
I tossed a few rotten ones and sorted out the good from the ones getting on the going side. The good ones I put up in a storage tote (a cooking pot for now) for later cooking.
Tumblr media
These ones are the contenders for the weekly meal/freezer prep. They had some funny or funky spots, things that can be cut off and thrown away or in the compost. I clean them after washing them well.
As a heads up, it's not suggested to feed chickens raw potatoes. So leave anything with raw potato bits in the trash or the compost bin.
Tumblr media
The bad bits.
If you feel need to you can wash them up again. I move to peeling after words.
Tumblr media
I save the peels for breakfast potatoes, or to make soup.
Tumblr media
A few peeled spuds.
Afterwords, depending on how many potatoes needed to be processed will decide what im making. This time I had enough potatoes to do cubed potatoes and hashbrown potatoes.
Tumblr media
Cube potatoes, then blanch them till all Dante in a pot. (Not quite to mash potatoes softness, but not crunchy.)
Drain, cool quickly. (If your into water conservation, save the water for your plants once cooled) I cool till just under warm and lay them out to drain/dry a bit.
Then take a pan and lay out a clean kitchen towel on it. Pour dry potatoes on and place in freezer till frozen.
Store in container and use like regular frozen potatoes.
Moving to hashed potatoes
Tumblr media
Similar to the cubed potatoes except I grated them.
I like to destarch my potatoes a little so I do a soak for about an hour, drain and then blanch.
I did about 5 minutes to blanch the hash, every couple minutes fish out a peice and test it to see if it's crunchy or just firm. Drain, cool asap.
Lay out to drain and dry a bit.
Lay towel on baking sheet. Place drained hashed potatoes on top. Place in freezer and freeze a few hours.
When frozen package up. Date and use as necessary :)
