Sawdust - compost or mulch?
I have access to an enormous amount of untreated sawdust and I'd like to experiment with it to make compost and/or mulch.
If I just stacked a load and kept it damp, would it be usable as a mulch in a few months?
If I layered it with greens, would it compost properly or would it still only be usable as mulch?
Would the result be usable everywhere in the garden or just around the fruit trees?
My soil is really thin and poor, and it's very hot and dry here in the summer, so it would be nice if I could convert the stuff into something that would improve the texture and water-holding ability of the soil even if the nutrient content isn't great. I'm also making a 'normal' compost heap to improve the soil generally, but there's two acres of poor soil so it's going to be a long job unless I can find a way of using what's readily available. I know the carbon/nitrogen ratio isn't good, but there's only so much 'green' available to add and it seems a shame not to use the stuff it it's possible.
Should I just experiment anyway to see how it goes?
