Does anyone know any merits of this kind of composting? I'm using more like a mulch thick and wide around my plants. Them seem to be doing pretty well.

I know the grass behind my bins is greener from the runoff.
I can take a handful of it and crush it between my thumb and finger and it most turns into dust. Like ashes from a burned piece of paper.

First of all, grass clippings should be left on the lawn to feed it, and bagged and composted only when necessary. Like when I foolishly put 75 lb of (free) weed and feed on my normally neglected lawn this spring, and had to rent a hay baler. Usually, I let em fly.

Second, sure, grass alone will make compost eventually. It'll get stinky and ammonia smelling along the way - at least any pile I've ever seen will. The smell is the aroma of nitrogen wafting away. Do you really want that? The browns are there to soak that up. Not layered as stated, but preferably completely mixed in.

The greater variety of ingredients, the greater variety of nutrients. Compost just grass and you have something good to feed the grass but maybe not much else.

I'm with Tox. Much better to mulch with the grass clippings. Either with a mulching mower or piling them on beds.

I took my neighbors grass only finished compost one time, since I needed more soil for a raised bed. It's completely different than my own compost. It's solid and hard dirt. Not useful by itself, but did give me volume to mix with compost, peat, and soil..trying to get something that plants will grow happily in, without spending money. This is the 'hard' way to do a project.

The grass only compost by itself is hard enough it's difficult to sink a spade in. Not something I would consider planting in. But this does make more sense than adding to your carbon footprint, having the grass hauled away, then purchasing finished compost.

I've never heard of hard compost. To me, when something is finished composting it all looks and feels pretty much the same. I'm trying to wrap my head around this and just can't picture compost so hard that it's difficult to sink a spade in.
Could you or someone else please explain more on this/
Thanks

I turn it regularly and never have an ammonia smell. But I also think I have left off an important fact.
I don't bag yard clippings except once every 6 to 8 weeks and it is an acre field full of grass, weeds and leaves. So I think CN ratio is a better than just plan grass which from I have been reading can range( depending on which site ) to 15 to 20. It looks like nitrogen blow off at 15-20 cn ratio is about 50%. But with a cn ratio of 22 nitrogen blow off falls to about 89% (once again depending on which site). Have no idea what my actual ratio is.

So the main facts are I am not just bagging plain grass, never get an ammonia smell, initial heat up settles at about 152 degrees through most of the pile. Then settles at about 130 for few weeks( turning every 3 to 5 days depending on my schedule). Then hovers around 100. Total pile reduces to about 1/4 of its initial size.

Watch the video I found and in my original post it is almost exactly what I am doing.
