Fishy, alkaline indeed it is, I'm just writing a paper on ancient and modern excavations in the chalk which is the major geological unit in this part of Dorset. The soil in my garden is what I have added over the years. There have been plenty of holes in the chalk from the Romans onward. They built a dam and an aqueduct all the way to Dorchester. Biggest hole though was Isambard Kingdom Brunel's railway to Weymouth about 100m uphill from my road. We have cob cottages, flint cottages and walls, chalk block and flint houses and the materials came from the hillsides and fields here. And I have boxfuls of chalk and flint fossils mostly picked up off the fields as I walked the dogs. A few miles westward and you're into clay vales and fertile greensand and a few miles east and you're into Hardy's heaths where rhodies grow in profusion and both are quite different geology and gardening to the chalk. Dorset is an interesting and sometimes confusing county if you're interested in the soil and it's potential.
