Has my compost got enough goodness in it?

[bogbean]

I have a well rotted compost heap which has been “closed up” for 9 months. It is made of garden waste, pure horse manure collected from the field, and unfortunately I did put some wood chips from the shredder on there (I won’t do that again). So, apart from the wood chips, it looks to me like a good compost to spread on my garden.Up to now I have dug in this type of compost but I’ll just spread it on top this year. However, my question is – do you ever add any extra nutrition to the compost? eg. add organic chicken manure pellets (is there such a thing?) or any organic type of fertiliser?
