Effects of field’s topology on energetic efficiency of rapeseed plantation for biofuel production

The model, developed earlier, have been designed to the studies of energy gain in the biofuels production, as compared to the sum of energy inputs on various production steps, and in processes enabling biomass conversion to energy. The present paper shows application of that model towards estimation of the contribution of energy used for commuting between agricultural production sites for a chosen example of plantation’s topological characteristics. Algorithm for computations is elaborated, and numerical example is shown. The sizes of the fields as well as distances between them determine the amount of energy spend for the agricultural work in addition to the tillage technologies being applied.
