Is there any special advantage of adding animal manures ( like cow dung ) to compost as opposed to adding green plant material( e.g., grass clippings, food waste)?
After all , we are adding similar material such as leaves , that animals eat , to our compost anyway .
Reason why I’m asking is because in urban area , I will have to buy animal manure whereas other ingredients are freely available .
What are your thoughts on incorporating woodchips to compost as opposed to using it only as superficial mulch on the surface ? Which in your view is more advantageous?
Also wanted to ask you whether you can plant vegetable & fruit plants in aged pure Compost ? Is addition of clay/sand a must ?
Last year I planted only tomatoes & coriander in pure compost -- they did ok.
Will pure compost need periodic additions of anything else ( like minerals & trace elements ) .

Thank you for your question. Here is what our farms expert says on this topic: https://extension.oregonstate.edu/news/turn-manure-compost-your-garden Without knowing your location or the type of soil you have, I cannot advise on soil amendments other than referring you to this publication: https://www.uvm.edu/sites/default/files/Extension-Master-Gardener/improvinggardensoilswithcomposting.pdf I would suggest finding a lab in you area that tests soil so you have scientific information about your garden. Good luck!
