    David Macauley’s illustration in the book The Way Things Work is how I learned about the beauty of the combine harvester

    Clearly a Promethean device

      Seems history shows innovations came from many individual sources but those Factory Farms weren't a thing. Corporations did help develop ideas into products but large scale Monsanto style factory farms weren't a thing during the time combine harvesters were being invented.

      It seems quite the opposite: the efficiency of the combine harvesters made factory farms much more likely.

      I think you might have missed the point of my story.

      Farmers were the engineers designing these things. Because that's all the kind of farmers there was.

      Now we have Factory Factory farms, but there are still some small farmers doing this stuff. We don't have many true farmer/engineers left. And it's bad for all of us.

          From my perspective this "pinnacle of human ingenuity" is actually a farse, because it relies on a monoculture and is therefore unsustainable in the long term.

          Don't get me wrong, the engineering is cool and I understand how important the mass production of food has been up to this point in human history, but there is another side of the story. The advent of machinery like this is part of why modern farmers use so many pesticides, herbicides, and fertilizers - a monoculture depletes the soil of its nutrients and decreases natural pest control, necessitating the use of chemicals. The use of those chemicals has in turn driven huge ecosystem changes that we are only just beginning to understand the impact of (such as mass pollinator die-offs, changes to soil microbiology, pollution of fresh water sources, pollution of cropland soil, and more) as well as impacting humans in ways we don't understand since some of those chemicals make their way into our bodies.

            One 4 meter line wheat and the next one a different crop, with 3 or 4 crops alternating, would be fine too. Especially with kilometers long fields.

                  You do know that crop rotation exists? It is absolute bullshit to say that using a combine harvester requires monoculture. You can simply rotate what crops you plant on a single field each year. This is also necessary if you care about would health and want to reduce efforts in fighting other weeds. If you also include Legominoses (idk if that's the correct word) into your crop rotation you reduce the need for fertilisers, due to them being able to fixate ammonium in the soil.

                    This is not really doable. It may be for small scale production of vegetables, but not for anything that needs great efficency. In the farming sector the trend goes towards bigger machines and bigger fields to increase efficiency and also to eliminate the need for work done by humans through automation. Concepts like this are incredibly hard to adapt, since they significantly increase the amount of work without increasing the profit. Also due to different plants having different needs it becomes significantly harder to actually harvest the needed amounts in order to make a profit.

                      I mean, one track can be as wide as a field sprayer as well. Not more work then.

                        For harvesting you would need to change the tool or adjust the machine for every row.

                          What, why? Barely two cultures have the same harvest time.

                          You seem to think of a lot of different cultures in rows. What i'm trying to say is, maybe 4 cultures in a field 4 times the size, but alternating rows.

                            They use physics and fluid dynamics (read: airflow) in a smart reliable way. Like all things in nature, grain has properties such as weight and mass, that are not the same for every variety. So there you have it. Lots of experience and engineering.

                              -circa the 70's- we call it 'green revolution' because we multiplied tenfold the harvests with mechanisation and standardisation. Back than the world wad hungry so it was necessary.

                              Today we see a weird phoenomenon where the abundance of resources changed customer behaviour and now we are causing the opposite effectes, effectively depleting the environment around us.

                              I can't type too much on a phone but the consistent way to learn this is following researches and learning the basis of soil maintenance, structure etc.

                              All that can be done with agromomy manuals and practical tips.

                              Even old ones really

                                  Materials science and the ability to harness adequate energy to drive such a machine. IOW, lighter, stronger metals, durable metals, bearings, lubricants, tire materials, quality fuels, engine power which is dependent on all the aforementioned, and all of that tied to close tolerance mass manufacturing.

                                  We really take for granted how fast and precise manufacturing has become.

                                  Even simple things we don’t think of. For instance - Cars from the ‘80s and before had interior materials that sustained UV damage and you’d end up a with fading, cracked dash, cracking seats, etc. Windshields would crack super easy from a rock chip. Now? The vast majority of car interiors remain in very good condition other than usage wear. I’ve taken multiple rock hits on windshields with many different cars and had zero cracks.

                                  Materials science is amazing.

                                    Just engineering in general.

                                    While my "google-fu" for finding resources is garbage, I have a cousin with nearly encyclopedic knowledge of engineering reference material. He's sent me things for figuring out where is safe to hang hammock chairs, acceptable bolt dimension/materials for car applications, and a bunch of other crazy niche things.

                                    That reference material for all this just exists and is generally just accessible still blows my mind.

You can simply rotate what crops you plant on a single field each year. This is also necessary if you care about would health and want to reduce efforts in fighting other weeds. If you also include Legominoses (idk if that's the correct word) into your crop rotation you reduce the need for fertilisers, due to them being able to fixate ammonium in the soil.

                                      Crop rotation is a great thing but still falls within monoculture. Planting a field with only one type of thing is the definition of monoculture.

                                      I seriously believe that cover cropping, intercropping, and examples like MonkderViete posted are the way forward - they result in higher crop yield per square foot and are more resilient in the face of climate change and pest pressure.

                                      You should learn about the benefits of no till market gardens - they are real and they work.

                                        From my perspective this "pinnacle of human ingenuity" is actually a farse, because it relies on a monoculture and is therefore unsustainable in the long term.

                                        Don't get me wrong, the engineering is cool and I understand how important the mass production of food has been up to this point in human history, but there is another side of the story. The advent of machinery like this is part of why modern farmers use so many pesticides, herbicides, and fertilizers - a monoculture depletes the soil of its nutrients and decreases natural pest control, necessitating the use of chemicals. The use of those chemicals has in turn driven huge ecosystem changes that we are only just beginning to understand the impact of (such as mass pollinator die-offs, changes to soil microbiology, pollution of fresh water sources, pollution of cropland soil, and more) as well as impacting humans in ways we don't understand since some of those chemicals make their way into our bodies.

                                        Any farming will deplete the soil of nutrients over time simply because we harvest things from the plants and ship them elsewhere and don't ship the waste or replacement nutrients back. Especially considering the insect die off, which at least moved some nutrients at random, though still not likely enough to make up for removing them at an industrial scale.

                                          If you can reliably predict what's going to be in your field, it's only a matter of time before you work out a machine for harvesting it.
