I get lost with the different systems that people use, i blame the tablets I'm taking.
I work on a three bed system, the only place that gets manure is where i put the potatoes. this bed is followed on by brasica And where the brasica came out of the rootcrop and onions go in
To much manure can be as bad as to little and make the soil to accidy.
My Bracica bed and root beds i use commercial manure IE groworganic raked in along with fertilizer (growmore or fish blood and bone) my onion bed only gets fertilizer (ammonia and fish blood and bone) i do this a couple of week before planting. I then put a ring of fertilizer around each plant when putting them in.
If you want to use hot manure then use it in heat sinks with some sort of raised bed to set potatoes away early,Basically hot manure covered with soil put the sets in cover with soil then cover the top of box/container to keep the heat in and the frost off
