Slightly related, but off-topic. It's astonishing how high-tech agriculture has become without the general public noticing much of it. I recently had a longer talk with my uncle, who is a farmer in South Germany, where he told me about the newish technology he is using: - Milking robots: the process is entirely automated, the cows basically go inside the milking stations by themselves. - His newer tractors are all dr…

> - A lot of data is collected for each cow and processed by an external company. This goes down to temperature measurements at each teat in the milking robot. The external company monitors each cow and plans individual treatment to prevent diseases and to optimize milk production. Very unfortunate for cows that they're able to produce milk for human consumption.

Evolutionary speaking, being tasty and able to produce milk for human consumption has been an extremely successful strategy for cows.

Of course, the individual cow might (or might not!) disagree.

Oh, I forgot a neat one: Drones with thermal imaging to prevent fawns to be killed by tractors.

Anecdote on this: I've been flying R/C planes and drones in some publicly accessible fields with friends for years. Some farmers were a bit confrontational when they saw us (sometimes understandably so, we were always careful but the occasional crash and aircraft retrieval in the middle of a field _did_ happen...). But a few of them were interested, and asked if we could arrange to take some pictures and videos of th…

There's business in routine agricultural overflights for year to year comparison and records, with multispectral cameras (expensive) for ANOVA plots when cross breeding for new crops with resistance, for rock outcrop plotting | individual large rock recording for { later pickup | hazard enty into tractor maps } etc.

A lot of that is done locally here ( large grain fields in Australia ).

But in the end you have to replace at least some of the nitrogen (and other nutrients) you are taking from the field in some way. And without a major shift in consumption patterns (less meat) this will mean fertilizer, as the alternatives usually lead to a much lower yield.

I was very disappointed on my last trip to Iowa to see that most farmers weren't even bothering with cover crops.

I wonder whether genetic engineering can give nitrogen fixing abilities to plants that currently lack this ability?

This is so great. My long term dream is that robotics take over farming, individually plucking each weed or weevil, and metering just the right amount of water for each individual plant, so that all the crops are organic. Most of the chemicals (yes, including nitrogen fertilizers) offset labor, so when the labor is free we shouldn’t need them. And people won’t have to spend their lives in stoop-back work or exposed t…

I disagree. I think we should have more human labor take over farming but on an individual level that's working much much closer to the consumption source. Think having your own farmer and food-producer in your own house or property, or perhaps shared with your small flock of neighbors.

Way too-many of the problems plaguing society atm can be solved by reducing transport and eliminating all the huge intermediate steps between our food (other other food-related products) and ourselves. Just think about how much effort is put into something simple like flour or butter or cheese (nevermind all the crazy processed stuff). The food will be more natural, it'll be healthier and with less additives, we'll be be contributing less to AGI/automation and creating actual valuable jobs, we'll be reducing the amount of plastic, fuel and electricity used for transport, storage, processing, packaging, labelling, accounting, lawyering. Every one of the major food production + distribution industries has huge support networks.

TLDR:

> Because drones spray or scatter the ideal concentration uniformly over a precise area, farmers require less pesticide and fertilizer than they would if applying materials by hand, says XAG engineer Long Hung.

I hope Long Hung knows that for sure and not just fantasizes.

Local, small-scale food production used to be the only way food was produced - people didn't eat better then, and there were many, many fewer people to feed.

There's huge variability in what can be grown where, especially if you want to reduce the amount and number of inputs that are imported from further afield. There are places that can support all the crops and livestock that provide a healthy, balanced, and sustainable human diet, but not everywhere can. What if you want to eat flour in a place where grain crops aren't tenable, or butter where cows, sheep and goats don't do well?

Producing food this way also means that we need to build houses on fertile land that's good for growing things. That happens a _lot_ where I live, and I hate the site of previously productive soil disappearing under concrete house-slabs.

In the article they didn't write about side effect but In Turkey My relatives also using drones for rice farming. And trees are dying since they need to fly drones higher then trees. Birds are dying as well.

Previously I remember there were so many birds but now there is none. I also remember there were frogs, snakes etc. and now there is none.

I wonder if drones will change the placement of farms. Right now, farms are very wide and flat, this makes it easier for tractors and spraying pesticides. Would be interesting to see overtime.

Terraced paddy fields have been used for centuries in countries such as Sri Lanka (where I'm from), Bangladesh, Vietnam and Indonesia. https://en.wikipedia.org/wiki/Paddy_field#/media/File:Pana_B...

It's not the plants themselves that fix nitrogen but endosymbiotic microorganisms in the soil.
