Primitive Technology: Sweet potato patch

The previous small garden was organised in rows (not seen in this video) but this was hard to water during dry weather. So I re-organised the patch into 1 meter wide mounds with pits in the centre. Vines were planted into the mounds and water poured into the centre of each mound watered the vines. So then I had a small garden with 9 mounds contained within it. I decided to enlarge the patch to fit in more mounds so I took out 2 sides of the fence and extended them by a meter each. So the patch ended up being 4X4m and contained 16 mounds. In addition to wood ash, leaf mould was added to the mounds for fertility and to reduce loss of moisture.
The patch, being in the dark forest understory, received only about 2-3 hours of direct sunlight per day so the yield was disappointingly small. Nevertheless, the patch produced a few small sweet potatoes and a single larger yam. I also picked some green growing tips of the sweet potato vine that can also be eaten. I boiled the greens slightly in a pot with a hot stone and ate the leaves. I then roasted the sweet potatoes and yam in the coals of the fire. The sweet potatoes (purple fleshed tuber) taste sweet and starchy whereas the yam (white fleshed tuber) tastes similar to an ordinary potato. After eating, I took the wood ash from the fire and poured it back into the mounds that were harvested, replanted them and watered them. In future I’d plant the sweet potatoes in an area that receives much more sunlight in order to dramatically increase production. I’ve grown the same variety at home and it produces a much greater quantity and size of tubers in full sun. Wood ash also tends to increase tuber yield and so is a good use for waste ash.
The sweet potato is a remarkable plant. It’s a staple food of many traditional cultures. NASA has considered it a potential crop to be grown on spaceships for long term missions. In terms of energy production it’s only 3rd behind sugar cane and cassava. It produces the most food value (a combination of edible energy and nutrition) of any crop per unit space and time. A study of Fijian farms using manual labour showed that ratio of energy put into farming vs yield of energy was 1:17 for rice and 1:60 for sweet potato. It grows on marginal soil and doesn’t require much nitrogen to grow. It takes a relatively short growth period of 3-4 months to yield. All parts of the plant can be eaten including the leaves which provide additional protein and nutrients. I grow the purple variety (because it tastes better in my opinion) but all varieties are nutritious and will stave off malnutrition. A person could potentially be nearly self-sufficient from a small plot of sweet potatoes. Note that in colder climates, regular potatoes could be grown instead of sweet potatoes.

That moment you realize you forgot to make a gate.

Wait. Guys. These videos take months to make, they require hours of manual labor, and he has over a million subscribers. Even still...he doesn't put ads on his videos. He da real MVP
-
We did it boys. We've entered the agricultural revolution
-
I love how he mulches it with leaves. I've seen way too many gardens have bare naked soil and then people stupidly wonder why it doesn't keep the humidity inside. I love this channel!
-
For some reason I find it incredibly satisfying to watch him eat the fruits of his labor.

Q: "If you were stranded on an island and could only bring one thing, what would that be?" A: "This fucking guy!"
-
"So, what are you up to?" Ah, just playing some survival mode.

Every time I watch one of this guy's videos and I see one of his huts, I just have to imagine going for a hike through the woods and stumbling onto a little village built by someone like this guy. I wouldn't know whether to be curious or terrified.

Please don't do a video with you talking. Us ORIGINAL fans believe that the sounds of nature are sufficient. Watching these videos are very therapeutic. They're also motivational to those of us with spiritual backgrounds. A lot of insight and wisdom from watching you refine everything in fire, mold things from straight mud, etc.

This guy need to be on "Naked and Afraid" like there's no tomorrow. In the next episode he will begin to construct his own airplane to escape the jungle.
-
If I had to live in some village in the woods, I’d want this guy to be the chief or leader of it

100% recycling! Impressed! Cuts wood, cooks and uses the ash. Then, he replants... nothing goes to waste... I came across this channel about 5 days ago and have watched 90% of the vids! simply amazed!
-
saving all his vids in case trump becomes president
-
Way better then discovery channel.

Мой восьми месячный сын смотрел затаив дыхание от начала до конца! Браво маэстро! 👏👏👏👏👏

That is a pretty sweet potato patch, well done.
-
When I was a kid I always wanted to live like this... Then wifi was created... Haven't left the house since lol
-
normal farmers: Rat poison This guy: SNEK

If someone discovered your place, they would call Nat-geo claiming ancient civilization have been found....
