Life Cycle Assessment of greenhouse gas emissions during wheat production: initial studies

Abstract

Key findings • Life Cycle Assessment (LCA) of no-till wheat production after short fallow in the North West NSW region using averaged district data has demonstrated that major sources of greenhouse gas (GHG) emissions are the manufacture and use of Urea fertiliser. • There is a need to extend LCA to examine the effects of replacing N fertiliser with legumes in cropping systems and provide other economically viable options to reduce GHG emissions.
