How disheartening Amanda ((hugs)) but I think your soil is tired - it did it's best last year but used up all the nutrients.
Which green manure did you use? Some (leguminous ones) will fix nitrogen from the air, but the ones usually used over the winter are primarily grown to stop the leeching of nutrients from the soil by the winter rains - if there's not a lot of nutrients there in the first place there's nothing to save. However, digging it in will help improve the soil structure.
I would put as much organic matter onto the soil this winter as possible - well rotted farm yard manure and home made compost if you can get it. Just keep doing this each winter and sprinkle some Fish Blood & Bone in the spring, before sowing/planting - according to the instructions on the pack.
Some Chicken Manure Pellets in the spring would be good too.
It will improve - our veg patch was very poor and stony when we moved here 3 years ago - it's unrecognisable now and very fertile (and full of worms ).
