fertiliser is applied in tightly controlled doses based on aerial analysis
Gotta say, this should be a huge red flag for everyone. Soil quality is declining sharply, and fertilizers simply aren’t making up the difference. Switching to robots farming will almost certainly accelerate this.
Use some Rokset on all your fasteners; the only way to break the threadlocker is with heat, and heat would also destroy the bodywork. So you could still replace damaged panels, but you couldn’t steal them.
I have an earlier version of this (got it on sale from Costco, and it was the highest-rated model by Consumer Reports at the time); I love it. It’s not great for carpets, but it’s fast and easy for hardwood floors.
Would I have bought it if it needed to connect to my cell phone? Absofuckinglutely not. Not in a million fucking years. It could have been the best goddamn vacuum in the world at sucking, powered by a miniature black hole, sucking dirt to the event horizon, and I still would have passed.
I need LESS connectivity in my life, not more.
That was a pretty roundly panned movie.
I quit flying (domestically, at least) over the x-rays and TSA bullshit. I’m driving 13 hours today in order to avoid that particular security theater.
Unfortunately most commercial farms aren’t putting in what they’re taking out, even with the industrial fertilizers. Most of the industrial fertilizers are just nitrogen, potassium, and phosphates, often as a liquid. You are absolutely right that you can’t take and never return; that’s why in pre-industrial revolution times, people would rotate fields between crops, and lying fallow/being used for grazing (where sheep, cattle, etc. were leaving free fertilizer) You also ended up with fewer years where all your crops got wiped out by a single pest, because you weren’t farming just one thing. Efficiency in farming–esp. monoculture–is great for profits, not so great for the land itself.
Eh. High levels of phosphates end up running off fields into waterways, and then you get things like algae blooms. Waste water treatment plants will clean up runoff that goes into the sewers and storm drains, but it’s not really cleaning up entire rivers. IIRC, that used to be a much more significant problem; I remember water in rivers near where I grew up–which was all surrounded by farms–often had white, sludgy scum anywhere that the current was forming eddies. If I remember correctly the high levels of that white shit was due to worse regulations governing agricultural run-off.
