Decomposition of Fertilizer Use Intensity over 2004-2011 in China

Abstract:

This study uses a complete decomposition method to analyze the nature of the two factors that influence the changes in fertilizer use intensity by crops: fertilizer use efficiency effect and crop structure change effect. We find that: the reduction of fertilizer use efficiency was the main factor in the growth of fertilizer use intensity in the aggregate agricultural economy, while the structure change had a minor effect on lowering fertilizer use intensity; the crop structure change effect and fertilizer use efficiency effect both have positive effects on the growth of fertilizer use intensity in grain crops; the decline of fertilizer use intensity by economic crops was largely due to the crop structure change from high fertilizer use intensity type to low fertilizer use intensity type, while the increase of fertilizer use intensity by horticultural crops was mainly attributable to the structure change effect.
