I've grown potatoes in bail of hay. Using different bails from different location gave me slightly different results. Growing potatoes in soil and adding manure was about the same . My soil here being sand so any nutriments are usually coming from ME.
I think its safe to say you probably get more Nitrogen from manure because of the urea in the stool. Coming from contamination or just naturally mixed in when the animal drops the stool ..
I also agree that grass clippings are good to use . But them weed seeds at times can be a killer... The composting allows the seed to sprout and be consumed, broken down, becoming useful nutrients ..
OK that said I feel manure is a better addition than grass .. I aslo depends on where or what you are growing.. Musa might do well on grass, But I feel Musa would do better on manure. As long as we are talking about adding it to the soil. Either one used alone as a substrate would need to be tested..
I have over 20 years of hydroponic gardening under my belt. I know things will in all kinds of substrate and feeding them all different kinds of fertilizers works well also . I have always noticed urea products enhanced the production.. Being there is a level of urea in manure I again think it better ..
manure = pre composted grass with the added benefit of urea Thats my .02
