Mark , I'm going to throw a spanner in now, sorry Verdun, there's not enough sod to trench there. It's too sporadic so you wouldn't get a sod to turn. Depending on what's been burned you're going to have an imbalance of nutrients or poisons in the soil. Wood burns will give you high potash, anything else you'll have contamination. Sowing anything on that may be a bit fraught. I'd seriously consider skimming off the top few inches and import fresh topsoil. It's not a large area so perfectly do able. Good new topsoil would give you peace of mind as well. Stoney soil won't matter, youll be less likely to suffer from moss. But good soil gives good grass and rectifying mistakes is always a lot of hard work.
