Collecting materials for composting

I have two large patches of Jerusalem Artichokes which are withering. I have cut them down with scythe

I ran the stalks thorough the garden shredder before placing onto the compost pile to speed up decomposition. I have coppiced many small Alder trees and now they are sending out new shots. Alder is a very good at fixing Nitrogen so I will make sure to cut them all down together with leaves and run them through the shredder. I have need for lots of compost soil and I better make that happen :)
