I let my 3 acres go fallow for the last few years (half an acre I mow so my kids can play and not come out covered in ticks). I wondered if it was helping a lot until I took a few walks in the grass and nesting birds were startled by my presence (I let them be after I knew where they were!). I don't think they'd had the chance to nest there when it was being cut for silage.
