I do garlic at commercial scale with fertilizers but my own food is grown 100% organic. There is a big difference in taste. What we should keep in mind though is that organic is difficult/expensive to scale. I doubt that it will be possible to feed the entire global population with 100% organic food. So that tasteless tomato that you buy at the store might not be the best but it does feed you.

The argument that it doesn't scale negates the majority of Agriculture's 10K+ year history. This modern system of chemically driven commodification of food is rather new (post WWII). Granted the World's population is larger than what it was back then, which introduces challenges, but the truth is we are facing disease due to the over-consumption of the 'abundance' more than anything else in the West, and the East is following as well.

While I agree the current monetary incentives are not aligned for its success, and the business model that had proven profitable for small scale, local and often organic farms working for the past ~15 years has been essentially curtailed due to COVID, as so many restaurants are limited in capacity or shut down altogether, it is not beyond the realm of possibility to transition how we view Agriculture and Food as a whole. I think this re-calibration is necessary for the challneges we face as Species on Earth moving forward and sincerely believe COVID may be the the disruption we needed to question the 'business as usual' model.

There is a great deal of efficacy to the theory/practice that soil remediation to be an effective deterrent in reducing atmospheric CO2 levels; at its core the way Biodynamics has operated since its inception when it was introduced to the nobility in Austria since WWI is nothing more than a distillation of viable practices that follow sound microbiology methods. It may be attached to a great deal esoteric 'woo' but once you see past what is essentially Marketing what you have is the collective synthesis of 10,000+ of trial and error in Man's relationship and the Stewardship we've had with the Nature. That much cannot be disputed.

People not entirely obsessed with this topic forget that a food supply not dependent on inputs like artificial fertilizers, herbicides and pesticides aren't that old and that some countries never adopted it due to the costs associated.

Explaining the significance of this topic without a great deal of context is entirely daunting but, large concentrated populations in former Empires didn't suffer because their wasn't enough BT corn to feed its cattle, and we would be remiss to forget that much.

Detroit's story with urban farming and the culture it brought back with it is a really amazing story that proves that something deemed not 'commercially viable' is not as important as the resilience of a community and a People if the will exists.

'Feed' is questionable, but what it clearly does is introduces a myriad of chemicals into your body that can and has cause(d) other health issues, all while still disappointing your palate.

There’s a cognitive bias where if you tell a certain kind of person a negative story about an environmental issue they will believe it, regardless of its content. If you read the article, none of the quoted sources say anything about depleted soil. It says it in the title, that’s it. Bait. What it actually says is plant breeding and other agricultural practices caused the nutritional decline. You breed plants for sto…

The alternative is not much better. If we didn't breed those plant for transportability and storage, then I agree its a problem, but its clearly what is working in the market. If someone has excellent tasting fruit but can't store or transport it, its a business opportunity (if they can pull it off at scale). Most of the time you can't, hence the popularity of gardening and eating 'in-season' produce

There's no scientific basis for my choice, but I have almost entirely stopped eating seasonal produce out of a season. I eat tomatoes in the summer and early autumn and then I patiently wait months to eat them again. When the winter comes I switch to vegetables that I haven't eaten at all or in limited amount for past half a year - beetroot, cabbage, carrot and more. I also eat all kinds of quality fermented, process…

Doesn't need a scientific basis -- in-season produce just tastes better.

For some it's not such a big difference but for others (tomatoes!) you might as well be eating a different plant.

Does anybody have a good suggestion for figuring out which produce is seasonal? Do you just buy stuff grown in/around your home country? It seems like I can usually buy any vegetable I want, regardless of the time of year, so I have no sense of when anything is in season.

This method definitely keeps things fresh (no pun intended)! My kids are really good about eating fresh produce but I've noticed that they also appreciate rotating new things in every few weeks/months.

Summer/autumn is easy - you can feed your kids new things every day. Jars (and cans) will help you go through winter/spring. I buy mine from the same folks I buy fresh vegies/fruits from.

> Not sure people realize how much scale modern agriculture has.

I do, I've admitted to be obsessed with the topic and have spent a large part of my life dedicated towards it. Look at my posts to see what I've done.

> Um, food riots were an absolute MAJOR thing in antiquity and right up until only very recently (This is very disingenuous and deflecting comment. What is being argued here isn't that food scarcity didn't take place, for that one really should look towards currency debasement, peasant uprisings, and the clashes in slavery and indentured servitude as well caste systems and feudalism as the likely culprits. Disease and blight both Human as well as crop (like the potato famine) also play a significant part in this story.

But what is being argued is that the advent of CURRENT Ag practices, those reliant on those inputs, aren't commonplace as you are making it out to be in the total History of Agriculture as a whole.

But it must be said that scale means nothing when the most obvious byproduct is disease (heart disease and diabetes kills more than thing else in the West and obesity has been endemic for some time) and destruction of the environment along with it. And that's where we are.

> Urban farming doesn't work at scale.

Urban farming, logistically speaking, is pretty much how most of Europe was built. The wars changed a lot of the landscape of many Capitals and metropolitan areas and displaced many farms outwardly as distributions and supply chains expanded, but in my experience with 15+ European countries I lived/worked in most of the country-side is built in such a way where the cities surround the farms/orchards/vineyards outwardly. They served as a sort of nucleus, which makes sense if you were going design a system to serve a growing population and it's civilization.

The exception being coastal areas that seem to have a more spontaneous pattern about them, likely due to port city trade/imports.

At least in north america, the supermarkets have to label where the food is from. You’ll begin to notice the difference between seasonal NZ and seasonal California, for instance.

I do suspect that there are sites and apps, but don’t know of any off-hand.

Blueberries that taste the same but are transparent in the middle. Tomatoes that tase water. Cucumber that look great and almost tasteless. You don't know what you are missing if you have never tasted the "real" deal.

I am certain that a vast majority of people have never tasted a "real" tomato. Here in the UK (though I'm sure this applies globally), tomatoes sold in supermarkets taste like plastic. Reason being is that they are picked when they are green and they "ripen" by the time they get to the store shelf. This is done because tomatoes are almost impossible to transfer safely in large quantities, because when they are ripe t…

I don’t know where else they have them, but in Canadian supermarkets we have vine-ripened tomatoes and they are actually sold on the vine in small clusters.

Turns out these taste very close to fresh natural tomatoes.

Source: I grew up picking tomatoes from my grandmother’s garden and eating them like apples.

This approach definitely works great! One addition I would make is canning / fermenting vegetables at their peak, so that you can enjoy them throughout the year until the season starts again (canned tomatoes, pickled cabbage, etc.).
