Hi Julie,
Like you we have brought in improved breeding stock to the local populace .
We came in from Cambridgeshire and live close to Ammanford.
I don't work the land per see as I'm a physical ( and some days mental ) wreck but I do have a fair bit of experience in crop growing and have still managed to grow things via a big glasshouse and numerous raised 900 mm high beds done in engineering bricks & filled with a decent mix of stable muck , sharpe sand and brought in top soil, as the soil here is about as much use as a chocolate tea pot .
I've been dragged up as a farm labourers colt in the wilds of Lincolnshire since 1950 and had my own small mammal farm and couple of acres to play with .
Happy to offer you any knowledge and experiences I have .
Have fun with clearing ..I had to remove over 90 trees with boles of over 10 inches diameter and all the associated scrub on the place I had .
We kept anything over 1 & 1/2 inches thick for the wood burner , then used the rubbish , brambles and leaves etc to help burn the roots that we dragged out once they were fairly dry then used the ash as potash on the new veg and lawn areas.
