Just make a few pots with 30%manure and 70% soil with some fast growing peas or bean seeds. If the second and third set of leaves look normal then your manure should be fine. Crops that arent as affected are sweetcorn and some brassicas.
If its just the freshness of it that you are concerned about its fine for all of those areas that have nothing growing, but make a pile to let it mature a bit (say 3 months) before you put in over things that are alive such as fruit trees and roses etc. dont ut it anywhere you want to grow carrots or parsnips.
good luck it works such wonders on the soil and your plants will love it.
but do a bean test first.
