We just need to add a mollusk treatment!

copper kills invertebrates (it's in a range of fishtank infection treatments, doesn't kill fish but will kill snails and crabs)

Copper kills funghi too, and that's a problem as funghi are important element of healthy soil.

We use a Lomi to convert our organic waste into compost I can add to my worm farm and then from the worm farm, mix with outdoor soil and grow in that. A automated a flood and drain system with our fish and cultivate nitrogen fixing bacteria with that, and water the plants with this water every couple of days. Using these two approaches I have not had to buy any nutrients in years and our soil is doing well. https://l…

Why get an electric powered gadget made of plastic and proprietary soft/hardware that will 100% for sure end in a dump in less than 20 years when all you need is a good ol compost bin? https://m.youtube.com/watch?v=bXZG-kzlhPY

I was originally pretty skeptical of the Lomi as well after seeing this very same video. But my friend got us one and we have been using it for a while now. Sure, it has the same parts as a breadmaker, and it's mostly just drying out and cutting down the organic material into more useful sizes, exactly like he says, but when you put in the enzymes and have it run its dirt cycle it does actually produce meaningfully good compost all with much lower footprint a garden composting setup. I'm not sure I'd pay to buy one new, but but it's not a scam.

and easier and time tested and resilient

Uh, pretty much every farmer I ever met is going to disagree. Farming is hard , unpredictable (prone to disasters/famine/plagues), and prone to all sorts of problems with soil, weather, etc. The reason modern fertilizer and pesticides are used so widely is they make that fundamentally extremely difficult process easier and more predictable.

lol yes, farming is hard as fuck. i'm comparing to growing food in high tech ways outside of soil

Plants absorb nitrogen and CO2 from the air and store it in their roots; plants fertilize soil. If you only grow plants with externally-sourced nutrients, that is neither sustainable nor permaculture. Though it may be more efficient to grow without soil; soil depletion isn't prevented by production processes that do not generate topsoil. JADAM is a system developed by a chemicals engineer given what is observed to wo…

The vast majority of plants do not absorb nitrogen from the air. Legumes are the well-known exception.

I think that's why it's good to rotate beans or plant clover cover crop.

When you say that you put a layer of old paper boxes against weeds, does that mean you put the broken down boxes first, and the put the compost on the top? If so, were the seedlings able to sink their roots through the paper boxes and go deeper into the ground? Also, what cover crops did you introduce?

I just put them dry, not broken, and overlapping between the boxes such that they cover the surface fully. And yes, the roots can go down, but weeds cannot go past that easily. The theory is yhe upwards growth is weak but downwards growth of the roots are much stronger and they can puncture a wet paper box. Cover crops: clover, buckwheat and winter rye. Cut before seeding and lay them flat over the surface.

Just to clear up what sounds like a simple misunderstanding, because you mentioned being in Europe: in the US (can’t speak for other English speaking countries) to “break down” box is to flatten it, not break it like to destroy or tear apart. As in “help me break down these boxes for recycling”.

Forgive me if you got that, it just sounded like you were talking past each other.

Here are the primary components that you would require - 1. Organic Matter: Compost and mulch enrich soil and improve structure. 2. Microorganisms: Bacteria, fungi, and mycorrhizae break down organic matter and enhance nutrient uptake. 3. Soil Fauna: Earthworms, insects, and arachnids aerate soil and mix organic matter. 4. Nutrients: Macronutrients (N, P, K) and micronutrients (Fe, Mn, Zn, etc.) are essential for pla…

Please - if I wanted to know what an LLM thinks about this, I would have asked it myself.

It really is a "nobody asked" kind of comment.

There’s not that much in the article, it’s more of a setting the case. Mention is made of “using AI” and other data sources, and that’s what I’d like to read far more about. I wonder if the new future is writing MCPs so agents can access the data.

"using AI" is just a marketing buzzword, a few years ago it would've said "IoT and Big Data", before that it probably would've said "DHTML".

Just remember that any positive effect you might achieve by a lifetime of composting is grossly negated by the production, usage, and inevitable way to the landfill of this thing. Startups like these are part of the problem, not the solution.

Lomi doesn't really "compost" your scraps, it dehydrates and grinds them. The actual compost activity happens (on an accelerated timeline, due to the pre-processing) in the soil you amend with your Lomi "compost." It's good marketing though

Odd that an article on healthy soil completely ignores the major health risk from growing food in regions with a long history of industry and mining, eg most of Europe, northeastern USA, etc. - Heavy metal contamination with species like lead, mercury, cadmium etc. There's a huge literature on the subject, but real-world monitoring is pretty light, certainly doesn't look standard: >"Freslyn Mae, Camata, and Ryna Mae,…

We’ve gone through rounds of working out if the leafy vegetables absorb the heavy metals or if it’s mostly in the dust and last I read we’re back to the latter. White vinegar is better at cleaning vegetables than so called vegetable soaps, and more importantly the acid dissolves soot and heavy metals. Gallon bottles of white vinegar are cheap. It’s also good for laundry especially if you have hard water, or a humid c…

> We’ve gone through rounds of working out if the leafy vegetables absorb the heavy metals or if it’s mostly in the dust and last I read we’re back to the latter.

It depends. For leafy vegetables it makes sense that dust > soil. However we find more lead and antimony in corn grown in proximity to highways.. this is clearly from road runoff taken up by the plant through the soil . We also find arsenic in brown rice and other crops again taken up through the soil because these soils are heavily contaminated from past arsenic-bearing pesticide use

But, dust/ topicals also matter. There is a reason fruits with thick skins like avocados, pineapple, melon, kiwi, always find themselves on the "Clean 15" list every year- because they are testing the flesh of the fruit, which is protected from topical pesticides by the skins. But I eat the kiwi skins sometimes...or make tea with the pineapple rinds... which people usually don't... and am guessing that they are a lot worse than the flesh.
