Because it destories the root structure built up in the ground over the years. Those roots then break down quickly, and in turn the whole microbe profile is different. Sometimes tilling is still the best thing to do, but it isn't a good thing and should be avoided.

On a different note, tilling also costs large amounts of energy. The less tilling your do, the less CO2 you are putting into the atmosphere (even if you do the tilling by hand with a shovel you are still emitting more CO2 than if you just sat in your easy-chair)

Does this still apply when talking about farming? I just started growing food this year, but once I've harvested the first crop and am planting the second crop of the season, the roots in the ground are surely going to break down quickly in any case, because I've harvested all of their tops, no?

I'm sorry, what? By that logic I should also never exercise.

I think many farmers have moved towards using various types of something called “cover crops” rather than tilling. These cover crops have different impacts depending on which are used: some have incredibly prolific rooting systems that dig deep and break up the soil on their own; some pull nutrients from deep in the soil and grow massive green above ground so farmers let these grow to pre-seed levels and then plow it over, and leave it so it decomposes and re-releases those same nutrients to the surface, and also draws all the micro biome critters in which then fertilize the soil even more; some plants fix nitrogen levels and some bloom various types of flowers which pull in pollinators. Some do a premise mix of multiple types of cover crops.

I think tilling is still done sometimes but it’s only for certain situations but is avoided most of the time these days.

I just got into gardening a few years ago, so I’m still learning most of this as I go along, but from what i’ve read, tilling is phased out except for certain situations.

I can say with absolute certainty that by my third year of working on soil, my gardens soil absolutely does not need tilling at all, it’s fluffy and soft for at least two feet down with plenty of life in there. But much of the surrounding area is pretty clay tough. Honestly it was super easy, just needed like a season of building the soil properly.

Another Ive noticed is, many of our home/hobby gardening techniques which our parents generation adopted were really only useful for enormous factory level farms and were actually not good for small or home gardens. These two situations need entirely different things but marketing and such over the years really steered that generation into doing a lot of the wrong things.

I don’t know your situation, tilling may be the best option for you, but it also may be to just dump a bunch of compost on top, let it settle, then plant some rooting cover crops and let it do it’s thing for a couple months. The latter may be much much healthier for your soil.

I guess it depends on a plant, but it's not only about roots. Top layer of soil has highest concentration of organic matter and it builds up over time when plants and possibly animal excrements decompose. By tiling you kill fertility a bit, that's why most farms have to use fertilizers.

It applies to farming in general. You really need to consult an agronomist for better answers (which can be very specific/different depending on which part of a field you are asking about )

I was hoping you would notice the exercise connection. I don't have answers to that, just an interesting consideration.
