This for sure has a million different opinions. All with validity!!! No doubt about it. On any side “well I plant XYZ way and it turns out fantastic!!!”
Everything has its +/- No doubt. Few lil examples off top of my head....
With a drill...
Downside: u need to treat the urea or use liquid so it doesn’t evaporate. Dealing with trash & residue is more difficult. Depth & seeding rates need tweaked. They are “somewhat expensive”, more on that in sec. can be heavy. Bigger equipment needed in some cases.
Upside: one pass & done. No disc/til, pack, spread, pack. Less equipment. Not hard on pto like tiller, way way less fuel used. Way less weed pressure: more successful plots, less spraying & less failures. Little to no erosion!!! Keeps moisture in the soil!!!
Can buy a used old drill, 5-7’ for $1500-4500 depending on what. I have a 2 box tye drill that’s 3 point, I think it’s 5’. $1500 & works great!!!
Disc or tiller:
Downside: stirs up weed seed. If erodible area- loss of top soil..... Extreme topsoil loss with tiller in erodible areas - especially if u get a gusher of a rain storm, less so if not. Tears up natural soil ecology. Uses tons of fuel & tiller is hard on tractor. Moisture loss. Need multiple pieces of equipment. Likely will need more sprayings.
Upside: can be found low cost - especially when used. Simple. Can make an incredible seed bed. Can put fertilizer into soil & avoid any evaporation. Can tear up residue & Make unworked ground ready for seed. Smooth out ruts & bumps. Anyone can use it with any basic understanding.
I’ve done fantastic plots with both. I used to use disc & packer on newly worked ground & go no till after that. I personally like a disc over a tiller for a long list of reasons, many are above (disc is less extreme on negatives) Now I do beans on new ground (no till) & drill every year after. There truly isn’t a wrong answer..... let’s say u have NHEL ground that won’t erode- it’s not going to be a massive issue either way. If u have slope & erosion- a guy really has to be careful & make sure Doing lot of extra steps to be on erosion, weeds, spraying, etc. both need a “fussy & careful operator” as “failures & issues” can come up with both. The risk with drill If do things wrong: crappy plot. Do things wrong with working soil: crappy plots + u could do some almost permanent damage to ground. Just go into it paying attention to detail & following a carefully put together plan tailored to ur situation. Good luck!
