I have just built some raised beds and filled them 3 quarters full of really well rotted manure got to be a few years old as looks just like peat.  Is it possible to grown direct in to this or will it be to rich.  I am gonna test the PH to see what sort of reading I get but wonder if there is anything else that i to be aware of other than the PH level.  Also will someone please advise me what the PH level should roughly be for growing most types of veg.

I have heard of people growing spuds direct in manure. You might also be able to do the same for squash but probably not root veg.

The vast majority of fruit and veg prefer a pH just on the acid side of neutral, so 6.5-7.0 is a good range to aim for.

Your manure may be a little too rich for some crops but others will love it!

The main issue is that unlike established soils it will have virtually no mineral content (clay, sand, silt) so will need to be topped up regularly, otherwise eventually it would literally disappear!

I would suggest that if you can you should fill the remaining 1/4 of the beds with topsoil, mix it all up, check the pH and take it from there.

It might be advisable to do a "bean test" before using it in case of Aminopyralid contamination.
