Herbicides have a long history of negative consequences. Glyphosate and paraquat, among other pollutants, are extremely harmful to human health and the environment. These pollutants impair soil quality and destroy beneficial organisms such as pollinators. Furthermore, the widespread use of herbicides has resulted in weed resistance, making chemical management less effective.
Kenny Lee, co-founder and CEO of Aigen Robotics, is personally committed to reducing pesticide use. Lee, a glyphosate-related non-Hodgkin lymphoma survivor, has collected $19 million for his startup to produce solar-powered weeding robots. “We’re on a personal mission,” Lee says, emphasizing their dedication to sustainable agriculture.
Doesn’t hydroponic farming already solve the weed problem without herbicides?
Hydroponics doesn’t scale in the way that traditional “stick a seed in the ground and leave for months at a time” scales, regardless of if you are doing it organic or not. This is also not the first “robot that will solve” agriculture. There is a mentality in silicon valley that they are smarter than everyone and just no one else has thought of these things. But this idea in principal has been around forever, and I even saw some demos at experimental stations I was working at back in the early Obama years. Pretty sure none of that went anywhere, but then again, robotics have gotten cheaper, etc.
The two best tech’s I’ve seen in this particular space were 1, basically a small hydraulic ram that beat the ever living piss out of small seedlings, and two, a high powered laser that smote small weed seedlings with the power of science. Either way, the places I’ve seen this work, its only on demonstration scale; very contrived circumstances; and always on extremely young weed seedlings. There also almost always seems to be a bit of cheating around the particular weed species. Consider the computer vision aspect: you need to destroy the seedling when its very young; many crops have weeds that are closely related and indistinguishable at that stage. So you’ll see demonstrations where its a dicot weed species in a grass species crop or vise-servus (or like, cheat grass in rapeseed, or some brassica in wheat).
But yeah. Inevitably it ends up being other issues that derail this. Small robots need to be kept track of, powered, etc. They get mud in their tracks. Birds shit on them. Crackheads steal them all and sells them for parts. They fall over sideways. And like, yeah you could build them bigger and heavier, but then you’ve just reinvented the tractor.
Weeds aren’t a problem, but typically the fertilizers for hydro are petroleum based, and therefore not sustainable.
Isn’t this the case for most of the ammonia based fertilizer used in all types of farming?
Yes it is. Haber-Bosch process is where all our ammonia comes from, and it’s fed via petrochemical stocks. No oil = no food.
I could be wrong, but I don’t think you can grow all plants in hydroponics. For example, anything that grows on trees(large root systems) as well as grain crops (where you need a lot of plants together, rather in individual pods like in most hydroponics).
The only alternative I can think of is a greenhouse system. Like what indoor botanical gardens use for trees, but instead designed for farming. That would be expensive(more than farmers could afford), but it would also weather-protect crops.
But you are right about hydroponics or aquaponics for a lot of produce, though!
More innovation at play so we can continue our basic lack of understanding of plant & fungal communities!
Technology for idiocies sake! Wee!
To be fair, some people dedicate their lives to the study of fungi and still don’t fully understand them. Hell, after almost being able to scratch the surface in my own personal studies, I am open to the possibility of mycelium being sentient. Having seen mycelium adapt to food sources the way it does, makes me doubt a ton of what we do know about them.
We probably have to seriously reconsider scientific naming conventions because of them, actually. They can evolve and adapt almost spontaneously and it’s crazy. (They is some spry little things!)
What I am saying is that a “basic lack of understanding” is the understatement of the century.
This, like most technical innovations in farming, has the problem that most farms are extremely cash/investment starved.
Basically anything that primarily benefits small farms and the environment doesn’t give sufficient return of investment for farmers to be able to borrow money for it, and they themselves have all their assets already fixed in expensive other farm equipment.
So the only ones that can benefit from this are the huge industrial farms with big corporate owners, and their (only) interest is to use it to cut labour costs.
