Ash as a dry ingredient for the composting bin

[Ohan]

This would mean you could make compost from just ingredients acquired through farming namely the inevitable, overwhelming mountain of crop seeds. 
 

The current allowed dry ingredients deter me from using the bin. id rather just get more cheap rot instead of wasting twigs and grass on compost. 

Cheapest dry ingredient is the pinecone and in my experience that only becomes abundant enough for composting late in the game.
