I'm less of a fan of hugelkultur beds outside of specific applications.

Tbh they are very nitrogen hungry and depending on how you've established them it can be a pain to grow things that have a deeper root system.

If you know what you're doing with them or you have an overabundance of logs, especially if you're dealing with large amounts of land, then go wild. But I think that you can get to the end result of hugelkultur beds quicker or more simply via other means.

If the end goal of hugelkultur is a loamy soil which is high in microbial/mycorrhizal activity then the quick route is to achieving that is by a more intensive route, which is applicable for a small scale backyard garden.

I'd be getting wood chips and/or sawdust and either burying them under a decent layer of soil or, better yet, I'd inoculate the wood waste with oyster mushroom mycelium to encourage the rapid decomposition of the lignin in the wood and making a large open-air mushroom bed. Because this will be breaking down quickly it will be stupidly thirsty for nitrogen but that's where the right manures and pissing in your garden is going to make a big difference. I'm unconvinced that chop-and-drop is really effective however.

The downside of this approach is that it's going to be difficult to grow plants in (except perhaps getting a lush harvest of oyster mushrooms, I guess?) but this can be mitigated by digging trenches, filling it with compost and suitable soil media, and growing in designated spots. This requires more effort but for a couple of years of mucking around with this, you'll end up getting to the end point much quicker and because you have used wood waste rather than logs for a hugel, you have the ability to dig down and create small pockets of ideal soil conditions for growing in while you're waiting for the wood to break down.

In-situ worm farming is really ideal in this application too.

To either expedite this process or to augment it, either for top-dressing the soil, for creating the trenches for growing, etc. or for dealing with excess wood waste I'd be making a Johnson-Su bioreactor if space permits.

Caveats that certain types of wood can leach compounds into the soil - yes "chemicals" - that may inhibit the growth of nearby plants. Either sourcing the right wood or using plenty of water regularly while also understanding that the next couple of years of gardening is just going to be a bit of a gamble is necessary here.

Also be careful digging trenches into heavy clay soil if your region has high rainfall or it's prone to bouts of torrential rain as the trenches can create sinks that fill up with water so ymmv.

Great advice about daikon radishes etc. if I wanted to amend heavy clay soil I'd be going for that every time.

the lasagna bed is what i was aiming for, but due to how my yard is set up it's difficult to get more than like 2-3 layers without needing a raised bed to keep the dirt from spilling out onto tiles/patio. to get around this i ended up doing a lot of digging to get the manure/rice hull mix into the ground, but ultimately things did not go quite as planned and i basically just ended up digging up most of my yard and burying a lot of poop underneath. i'm not sure what to do next, i could just stick to the plan and keep mulching with a poop/rice/coir/dirt mix and cover with cardboard, but i'm worried about smells and bugs when summer really starts rolling in. also the dirt is way too elevated without even mulching and will definitely start spilling over into the rest of the yard if i mulch.
