I feel like we already knew this was caused by poor soil quality? Like, we fertilize fields with ammonium nitrate, urea, and diammonium phosphate. You'll notice there's no potassium, magnesium, zinc, iron, or copper being added back. There's less in every harvest.

The good news is that we already have the tools to fix this, in breeding, soil health, markets and policy.

There's literally nothing breeding can do to add micro-nutrients back to our food, and markets got us to this point.

The only solution is policy targeting soil health, and that's it.

That will not add potassium, magnesium, zinc, iron, or copper to the harvest. That only comes from the soil.

Ah I was talking phytonutrients vs micronutrients I guess.

We can fix the soil for micros but we have to re breed the plants to fix phytos

Without even opening the article, let me guess. Industrial farming ruins the soil and so the crop can’t absorb the nutrients because they’re just not there? Almost like large-scale profit-first thinking comes back to bite our collective arses like it fucking consistently does in all other areas of life?

The strains of vegetables are at least as much of a factor I would presume. They have been going towards GE crops to take pesticides more and produce higher outputs.

It's mostly that, not the soil, as they use fertilizers, which do work, despite many of those fertilizers being sewage, (which is a legitimate, traditional, and good fertilizer,) that is mixed with industrial waste from municipal water systems.

It's all fucked.

You can’t continue to farm on the same land season after season. The soil needs to regenerate. Rotational farming practices is the key not dumping nitrogen into the soil and constant tilling. You get zero water retention and poor soil health / biome.

You can buy produce labeled as organic or Bio depending on where you are. You can also support your local farmer's market. There's a small traditional farm close to where I live that lets you harvest tomatoes yourself in the summer and they definitely taste very different from the ones at the discounter.

Why isn't composting part of the solution? If those minerals aren't going into our bodies then they should at least be returned to the soil instead of to the dump.

Basically, the mineral components in the soil - whatever rock the soil particles came from - undergo chemical and physical degradation, releasing micro nutrients bound within them.

Potassium is a good example even though it's a macro nutrient - the mechanism is the same for the most part

Rock is the slowest but largest pool of nutrients like K. With K in particular, clays can bind it and desorb it depending on clay type and hydration status. That K is generally more available to the plants.

Think of it this way: you have a mountain with diamonds in it, and a pick axe. That's your mineral K. You can chip away and get more diamonds but it's hard to do so and time consuming.

There's also a smaller pile of diamonds that you can just sell to people. That's your available K.

Then there is diamonds you are getting polished, that can later be sold. That's your clays

This is well-known, just not widely discussed.

It's a combination of soil being depleted from micro minerals, and every plant is bred for yield, not flavor or nutrition.

I think you forgot potash, which provides.... let me check my notes.... potassium. And micronutients like zinc, boron, copper and mag as well as many others are applied via seed-placed fert as well as foliar application.

Nobody here knows shit all about how crops are fertilized, obviously.

Agreed. I did see that farms that apply for or keep an organic tag must rotate the crops to keep the tag. Right now only about 15% of our (U.S.) crops purchased are organic but I would imagine with education and policies/regulations.

It may be harder for specific crops like corn, but they supposedly have already seen nutrients rise greatly in situations where they have rotated the crops by such policies.

Hopefully it's a problem that can be solved pretty quickly.

As with anything lobbying will promote misinformation and strawmen that will slow down fixes .. because the health of others doesn't matter more than having an extra profit.

Anything that says "regenerative farming". I grow some of what we eat and don't use much fertilizer just get good local compost dirt and try to rotate crops.

Our ecosystem has a limit to what it can support. Some people call it a 'carrying capacity', but I prefer to call it 'Shareholder Returns'.

I learned something new today...

Crop rotation is a required practice, in the United States, for farms seeking organic certification.[24] The “Crop Rotation Practice Standard” for the National Organic Program under the U.S. Code of Federal Regulations, section §205.205, states that

Farmers are required to implement a crop rotation that maintains or builds soil organic matter, works to control pests, manages and conserves nutrients, and protects against erosion. Producers of perennial crops that aren’t rotated may utilize other practices, such as cover crops, to maintain soil health.[13]

(From Wikipedia article on Crop Rotation)

I had never realized that. I generally don't pick organic because I believe that, for the most part, the majority of "organic" farming is mostly marketing geared at anti-science people, and fully organic farming is not scalable enough to replace modern ag.

But that's definitely a tick in the "pro" column.

I'm today years old when I realized that most many, if not most, types of rocks contain carbon and potassium.

C and K. That's half of being a rock.

Compost and manure also add back nutrients.

Yet, soil quality is declining, as is stated in the article. Why? It seems to me that farmers aren't adding back nearly enough, and are just relying on nitrogen and phosphorus. Maybe because it's cheaper and easier to apply, but I can only guess at why they are neglecting their soil health.

There's different levels of farmers, but the ones that stick around are the ones that pay attention to soil health because it's where their profits are made in the long term.

But most of them consider themselves doing a pretty fair job of keeping soils healthy. It's not always done how the keyboard warriors want, because of realities on the ground like sourcing and transporting large amounts of compost and manure, or the excessive cost of manufactured but easily transportable fertilizers.

And it's pretty funny to watch people bitch about the ethics of livestock on one hand, but want farmers to use manure on the other. If you can figure out a way to strain the PFAS and chemicals out of city waste and make it a non-toxic mess, then get it to where the food is grown, I'm sure everyone would be all ears. While you're at it, get that food waste gathered up and put it on a truck. I'll take it in a heartbeat.

I've gotten very used to how Lemmy despises farmers, it's pretty depressing actually to work like a dog for next to nothing in order to have people hate you for feeding them.

"not flavor"

This one hit;s hard. I was getting seeds at a food bank to grow peppers. I went on to say, oh you need to starve them of water (increasing potency) and the twat told me "I guess you're not hungry enough" sigh the whole point of hot peppers is to flavor that potato I was going to eat.

The article talks about zinc and selenium, which are metallic elements that are not regenerated in soil on seasonal timescales. We'd need millions of years for the crust to renew and dredge up more rocky sources from the mantle. It is a mass balance problem - each bit of zinc in the wheat you eat used to be out in the field, but now it is in your body until you excrete it as waste .. then it probably ends up in the ocean or a landfill depending on where your water treatment plant is. Very little waste is recovered for fertilizer.

The solution here is going to be more fertilizers, not less, with micronutrients sourced from mines with richer deposits than the soil holds. The only other solution is moving food production to virgin land, which means destroying even more nature and will ruin that soil as well in time.

See also phosphorous, which the world is rapidly running out of. Phosphorous is regenerated through sedimentation in the ocean crust, and subsequent tectonic activity moving that crust to the surface. There's less than a century of phosphate rock reserves left. Fertilizers won't even be an option in this case, and it is a slow-motion emergency.
