I'm new to LCA and openLCA so I want to ask a very beginner question.
Through field survey, I had estimation of nitrogen input amount per function unit (like 500 gr Nitrogen for 1kg of cocoa beans). How can I define this amount as flow into cocoa production system at farm gate, and also define their environmental impacts using available database (like WFLDB etc) ?
I check many flows in the database with keyword Nitrogen in openLCA, but they showed up like Elementary flows / Emissions to water/ River .... They were seemingly about elementary emission flows rather than elementary input flows.
Thank you for your help.
