Influence of Tillage Technology on the Energy Efficiency of a Rapeseed Plantation

The paper aims to evaluate the energy efficiency of a plantation as a function of amounts of energy required by the agricultural production processes. Computations were based on derived mathematical formulas, and the elaborated algorithm was implemented as a macro in an EXCEL spreadsheet. Obtained results applied to rapeseed plantations at various conditions concerning the structure of a plantation and applied agricultural operations. On the basis of the results, the EROEI type of indicators is strongly dependent on the choice of production technology, as well as on several aspects of workflow organisation.
