Modelling of maize and rapeseed production for biofuel potential assessment

Abstract

Maize and rapeseed are among the most widely cultivated crops in Poland. The aim of this study was to develop a model enabling the estimation of the potential yields of these crops and the assessment of their energy potential. The model was based on data concerning cultivated area, yield per hectare, soil quality classes, and drought-related yield losses. Each agricultural parcel was analyzed individually, allowing for precise yield estimation depending on local conditions.
The analysis showed that in 2023 the total energy potential of biomass derived from maize grain and rapeseed in Poland amounted to approximately 332,879.4 TJ per year. Maize accounted for the largest share, both in grain and silage production (233,251.1 TJ per year), while rapeseed – mainly winter rapeseed – contributed approximately 99,628.3 TJ. The results confirm the importance of accurate crop production modeling for reliable biomass resource assessment and for planning the development of renewable energy systems.
