Do you have access to compost? That would be a start. Access to aged, well-rotted manure of any sort would also be a huge help. But it has to be well-rotted, not fresh. Neither will add a huge amount of nutrients to the soil but they will aid things like worm and healthy bacteria activity which are very important. If you don't have direct access to manure, have a look around a good garden centre for bags of things like mushroom compost.
If everything grew well last season, the soil is obviously still healthy.
Re posting a photo. In the panel across the top of the posting box you should see a symbol of a tree, second last symbol from the right hand side. That's where you start. Then just follow the instructions.
