if its lump then give it a good whack with the back of the fork, quickly move on to next dig, at the end just rake the surface flat. it would be ideal to get a rotivator if you haven't done so already, generously sprinkle some sharp sand,manure on top, and rotivate it. over time you will notice soil lumps will break up nicely with a gentle squeeze.
i found most things grow in lumpy soil. i st had lumpy clay soil so potato's and carrots struggled but others were ok.
