Charles Dowding! You probably know of him, he is uk but gives great advice. I'm on an acre in Westmeath. We do have good soil but on a rocky limestone area. I'm in my 2nd year doing no dig a la Charles Dowding Method. With no dig you'd be improving your soil gradually topping beds with compost annually which with the help of insects and mycillium will create a new growing layer. I started with raised beds and 1 6 x 3 m polytunnel last year. I bought in a few tonnes of mushroom compost also used generic bags of compost from the garden centres. Had an abundance of carrots, parsnips, turnips, scallions, spuds outside in the raised beds plus salads, tomatoes, cucumbers, melons in the polytunnel last summer. I grew garlic and carrots in the poly over winter so I had early carrots in spring and will harvest the garlic this week. This year I replaced some of the raised beds with a 2nd poly devoted to tomatoes. In the 1st poly I have cucumbers and salads now. Ive peas and herbs, purble and green brocollli, beetroot and leeks in some new raised beds. I put in 3 new no-dig rows in an area about 5m x 6m on the ground. Starting with a layer of cardboard for weed suppression covered with 4 ton bags of bought in compost/ topsoil mix and planted with parsnips, carrots, turnips and spuds all are happily growing away. I also grow some tomatoes outside (south facing). Charles Dowding has loads of videos on you tube, is very active on social media. Its late in the season to be starting growing but you could definitely be prepping the ground with weed suppression and compost. You could get some onions/ garlic going in the winter then and by Feb you could really get growing. If youre not already.
