Oh this is fascinating. I know it’s vulgar to talk money but I would rather get a lower but still worthwhile yield from a free growing medium than a higher yield from expensive potting compost. I’ve grown a pot of potatoes in sieved leafmould ( with a handful each of chicken manure pellets and blood fish and bone) and they did well. Next time I’m planning on adding some home made compost to the leafmould and save on the fertilizers. I’m cheap.

Me, too. I value decent sized potatoes as they're easier for me to deal with in the kitchen, if they have any green and need peeling or what-not, but otherwise I'm totally there. Basically it usually just good exercise of ones brain and maturity to have those thoughts and values, making exceptions at least knowledgeably and purposefully ( like, I know it's a splurge but I'm going to buy this, or spend more for that). Not to be stingy or greedy, but to care well for your own needs and savings avoids unnecessarily being a burden on others, and the more you have extra, the more good u can do with it. In farming, the benefits are also seen in cow health, when farmers went to rotational grazing and less grain, resulting in lower yields of milk BUT also lower costs, over-head and greater cow health & longevity, and happiness, less stress, of the worker/family. Off topic but u made me think of it :).

Apparently if the compost is too nutrient dense at the start, you immediately get a high number of tubers. If the medium is unable to maintain this high level of nutrients, these tubers never develop. And so to get bigger potatoes, sow in an average compost and then feed later in the year as the tubers are swelling

The first year I experimented with potatoes, I grew them in dry leaves and leaf compost, yeilded about 5 lbs. From only about 5 potato pieces. I was fascinated. The second year I grew them in about 3 inches of compost then topped off with dried leaves, I planted about 10 potato pieces, yeilded about 10 lbs of potatoes. I am still fascinated. I've been growing things for a long time but honestly potato plants are quite fascinating, and so easy. I don't many potatoes but I sure do love to grow them. In planters, in the ground, in new beds and old, it's so rewarding. :)

Thank you for this experiment and for sharing it with us, Charles. We made some raised beds last Summer and I was going to fill them with horse manure from our village stables (I thought it was natural, free, nutritious and closing the gap locally). I am so happy I did some research before filling them up. I was worried about the antibiotics they probably had given to the horses and them making their way into our bodies. It's refreshing (and worrying at the same time) to see the results of the others and the horse manure 🤢 How terrible if someone does all the work of growing their own to improve their health, and this happens... 🙏 Keep up the videos, Charles.

Just remember/be aware, that when disturbing the soil when harvesting potatoes, that the more advanced your no-till garden is, the more you'll be able to simply pull them out and easily reach in to gather any u suspect r still there, without completely destroyed a giant hole, like can be "normal" otherwise. Then too, with the undisturbed paths between the rows of hills, the relatively small, disturbed area has a lot of UN-disturbed borders to send in re-populations, healing, growth, quickly. When watching a fairly recent webinar series on some soil life basics, with Elaine Ingram, on KZfaq, I learned that.

That was really interesting. Imagine the yield if you mixed it all together, EXCEPT the weed killer of course 😁 I actually buy my mushroom compost a year before I use it just in case there are aminopyralids in there. I slowly mix it with many of the mediums mentioned in the video so that things have a season or two to merry and then I amend with it. I have seen whole properties so affected by aminopyralids that I don't trust anything that I bring in. I am just using the last of my garden potatoes now. I will be growing more in the spring. I do wish suppliers would have some short season seed potatoes for mid season planting though so we can harvest in the fall. I manage to do it with some potato varieties so at least I get some. I mean, I get it, since we are a shorter season but I can still get a round of lovely little fresh potatoes in October where I am. Of course, I am a brave(or crazy) gardener, haha!

Potatoes is a steady crop and we are grateful for that. What more is to say is that with potatoes it is like most of the other crops, they like the best weather for its species. They do not like it to hot, we get more tasty bulbs up here in the north of Sweden compared to the south. In my opinion they give the best harvest with a solid temperature somewhere in the middle of the scale and not to much rain. We plant them traditionally in a field with sandy soil, plowed by the village farmer, fertilized with cow manure. Usually, with the combination of a sunny but not to hot summer and a regularly amount of rain we get a very good harvest. In garden i use to have 3-4 pallet bins for potatoes, growing them "vertically"- I put the seedlings on the ground and put soil on them, then keep putting more soil on the growth and end up with 2-3 pallets on each others in the end. I have found it an easy (and cheap) way to get a lot of bulbs on a small area and a perfect way to expand the amount of a new variety. I have the same soil everywhere in my garden; cow manure at the bottom of my beds and a mix of soil from the fields, recycled soil from the seedling pots, sand and a lot of leafs. Blending the recycled soil, sand and leafs in a bag in autumn and spread it out on the beds, working fine. In spring I fertilize with a little manure from the chickens on the surface of the beds and later on I water with a "soup" made of nettles, comfrey and dry and hard pieces from the cow manure, once a month.

an interesting trial would be comparing a no dig bed with compost to a no dig bed with same compost but with balanced npk fertilizer added, say half strength, maybe another full strength

@CharlesDowding1nodig 8 ай бұрын

Cheers Barry, only I could not bring myself to do this because of how synthetic fertiliser damages, the soil's microorganisms. See this study by a farming centre in the UK, "Inorganic fertiliser application reduces both the species richness and diversity of bacteria in the immediate vicinity of wheat roots. We’ve shown the amount of growth promoting bacteria living around the roots was 91% for unfertilized plants whereas for fertilized plants only 19% were found to show beneficial traits." www.rothamsted.ac.uk/article/kicking-habit-fertilisers#:~:text=Inorganic%20fertiliser%20application%20reduces%20both,found%20to%20show%20beneficial%20traits.

Fantastically well structured video and even a fancy stick the hand in the compost sack transition haha! Could it be that the horse manure was still breaking down? Like you said it was still warm? Also if you would normally expect potatoes to grow well in %100 horse manure like that, then that should be an indication of just how much chook poo you could add to the wood chip bags (lots!). Red Gardens KZfaq channel just posted a very similar trial with 180 sacks you may be interested in watching. From memory, chook poo added as fertiliser didn't perform well for them. Did you give up on the weed killer bag? Would have been interesting to repeat it for a few years to see if it broke down. Thanks for the great video!

Great video as always Charles, thank you. I recently cleared a new veg bed in my garden, and am preparing it for the year ahead. To improve the soil I mixed in a few bags of rotted horse manure from B&Q, which has done pretty well for me in the past. However, now I'm worried that I've brought in some horrible chemicals with it. It's currently under cardboard and will sit for a few months until I start planting in spring - do you think that's enough for the micro-organisms to break it down? I'd be grateful for more information on it. If you're looking for ideas for the channel, perhaps you could interview someone about it, to advise on how long the effects can persist, and ways to avoid it? Many thanks!

@CharlesDowding1nodig Жыл бұрын

Well, I have already made two videos on it since suffering poisoning in 2014. I've had a lot of contact with Dow-Corteva chemical company who make it and who were not helpful at all. Their advice is to rotavate the soil to bring it into contact with microorganisms, but they obviously do not realise that rotavated soil kills microorganisms! I have since discovered that best degradation is through sunlight so surface application is best. Yours might be okay and you could put a little in module cells or small pots and sow broad beans on the windowsill, to find out within four weeks if growth is healthy. Beans are very susceptible.

@@CharlesDowding1nodig Fantastic, thank you Charles. I'll look up those two videos. It's a new bed from which I had to remove a lot of Montbretia, woody shrubs and carpeting perennials, so I had to disturb the topsoil to get all that out. While it was already disturbed I dug in the manure, and laid cardboard over the top. It'll be about three months before I'll plant anything there, so hopefully that will give it a chance for the microorganisms to reestablish and break down any chemical residues that may be in it. In future years I'll not dig it again, and will mulch with my own home-made compost. If using manure again in the future I'll make sure to look out for certified-organic manure. It'll be more expensive, but at least I'll know that I'll not be exposing my family to any horrible chemicals.

Really interesting results Charles, and very frustrating about the weed killer in the horse manure. We recently had some of our allotment holders suffer similar results from a delivery of horse manure. I can’t say just how annoying it is. On the plus side we have had much better results from our composted cow manure, so much so I’ve taken a delivery of another 5 tonnes just the other day.

Great video and I was very surprised with the wood chips yield but I'm guessing if it's actually become compost then of course it has the nutrients and microbial life as do the others. Pity about the horse poo - I'm fortunate to have a daughter with three horses - have to be quick though as the dung beetles do an amazingly quick job of carting it away! Oddly, the best yield I've had in almost 50 years, was in clay too hard to dig - I just laid the spuds on the ground and did a horse manure, hay and straw lasagne on top. But the staggering thing was how this changed the soil - top inch or so was dark, friable and with soil life. Haven't dug the soil since, and since finding you quite some time ago, only use compost (my own or mushroom). It's extremely hot here in the Riverina NSW so I do add sugar cane mulch. Absolutely love your informative videos and you keep inspiring me to try things - even though my vegie patch is small it takes up my entire back yard - love, love gardening and seeing things grow. 👩‍🌾

Interesting comparisons Charles thanks for taking the time throughout the year to produce that video. Interestingly I have just combined some 6 month old horse manure with my ordinary compost in layers to let it rot down for next year. However there were lots of worms in the ordinary compost and none in the partly rotted horse manure, I am wondering if this is an indication of the same problem you had with your horse manure. I hope not because it is my main source for compost production.

@CharlesDowding1nodig Жыл бұрын

Glad it was helpful Graham and worms do not populate the compost any differently in my experience, whether there is poison or not. I find it amazing also that horses eat the hay and apparently do not get ill. I suspect there must be long-term damage, but hope not! You can always take some horse manure and sow broad beans in it, you will know within 3 to 4 weeks. If they are healthy and normal, all is good.

I put them in our sun room where temps are in the upper 60's to around 70 F and they get plenty of sun. I won't be planting them until at least April. Can I chit them that long?

Good Afternoon Charles, I wonder if I might be cheeky and ask what you use or recommend for slug control. I follow your no dig process and have good results, however this year I have lost quite a lot of main crop potatoes to slug damage. Is there a variety that you can recommend that is more resistant?

@CharlesDowding1nodig Жыл бұрын

None Peter. It's fine to ask, and I find that with No Dig, there must be good populations of slug and slug egg predators, such as beetles and toads. Plus with potatoes, I never grow maincrop because I want the harvest before end of July, so I can put in second plantings. That means less slug damage because we remove potatoes as soon as they are finished growing or even before, and that's before slugs as well mostly! I hate pellets and do not use them, even the so-called organic ones.

I would be amazed, if your old manure, which is essentially is compost, could cause contamination to the well. Especially from being spread on the surface, because then it is fully aerobic and healthy without harmful bacteria.
