Abstract
Life cycle analysis method was used to establish an inventory of a winter wheat production system that employed the Soil Testing and Formulated Fertilization Program in Linqing county, China, after which the net resource conservation and emission reduction benefits were calculated, evaluated and compared to the winter wheat production system in a conventional fertilization area. The results revealed a great reduction in resource consumption and emissions of the winter wheat production system in the program demonstration area. From 2006 to 2010, the life cycle reduction potentials of eutrophication, and acidification potential per ton of winter wheat accounted for 12.09-30.31% and 1.40-4.52% of the relevant environmental impact potential per capita worldwide in 2000, respectively. The Program significantly decreased the environmental burdens of the winter wheat production system, and farmer’s fertilization behavior tended to become rational.
