Notill doesn't work here, but it's sure a time and money saver in places it does.
Roundup is starting to not work here, need something for the tough broadleaves that are resistant. This may be a worse problem in notill, if not now soon in the future. It shows up almost overnight. Something to keep in mind.
Lot of folk like to put p and k on in fall, feel it needs time to be in the ground. With notill, you especially have a situation you build up the soil nutrients right on the surface, but a couple inches down where the roots are there isn't anything really. Then, if you get any wind or water erosion, that super rich top 1/4 inch of nutrients is the most likely to get removed.... Broadcast fert in notill, I think you end up putting fert on this year, that will eventually be used by the crop 5 years from now when it finally gets worked in a bit.
Some sort of strip till, or banding the fert into the soil a bit, would seem helpful. One has to be careful with beans tho, they don't like fert too close to the sprout in strong doses.
It's a tough thing, you have to work out for your own farm and goals and long term........
I do all my p and k (and N for corn) in spring, granular. The coop broadcasts it with a variable rate air spreader, and I work it in in a day. Even worked in, I believe a lot of fertilizer ends up being used over a 5 year period, anyhow the p and k, and one is kinda trying to average out good over the long haul.
I guess others would know a lot more about notill and can laugh at my thoughts and steer you right.
