EUE (energy use efficiency) of cropping systems for a sustainable agriculture

Publication year: 2011brbSource:/b Energy, In Press, Corrected Proof, Available online 13 May 2011brFrancesco, Alluvione , Barbara, Moretti , Dario, Sacco , Carlo, Grignanibrenergy efficiency of agriculture needs improvement to reduce the dependency on non-renewable energy sources. We estimated the energy flows of a wheat–maize–soybean–maize rotation of three different cropping systems: (i) low-input integrated farming (LI), (ii) integrated farming following European Regulations (IFS), and (iii) conventional farming (CONV). Balancing N fertilization with actual crop requirements and adopting minimum tillage proved the most efficient techniques to reduce energy inputs, contributing 64.7% and 11.2% respectively to the total reduction. Large differences among crops in energy efficiency (maize: 2.2 MJ kg−1 grain; wheat: 2.6 MJ kg−1 grain; soybean: 4.1 MJ kg−1 grain) suggest that crop rotation and crop management can be equally…br Highlights: ► We evaluated the energy flows of integrated as alternative to conventional Farming. ► Energy flows, soil organic matter evolution included, were analyzed following process analysis. ► Energy flows were compared using indicators. ► Integrated farming improved energy efficiency without affecting net energy. ► Inclusion of soil organic matter in energy analysis accrue environmental evaluation.

    Hi. i am phd student in iran ferdowsi univercity. i am going to work at desighning crop pattern based on energy use efficiency and sustainability agriculture for my tezis. please send pappers about this matter.with thanks.
