Raw manure under new turf?
I'm removing some gravel from around a quarter of my back garden so I can have a lawn at last
Under the plastic sheet it's very compacted - I believe it's been down for some years. The soil is clay, but not too heavy. As nothings grown in it in a while I'm thinking of feeding it before laying the turf - a load of manure would be free (though I'd need to collect and bag it) and help the soil structure.
Due to the compaction I'll be hiring a rotavator to do the hard work so I could throw some manure around before/during going over it.
Should I let the manure rot for a few weeks before using it, or spread it around and let nature take it's course with the raw stuff. If I do this can I lay the turf straightaway or should I leave it a couple of weeks?
Or is it unnecessary? There are a lot of worms so the soil isn't "dead".
