Assessment of cost and energy effectiveness of modified technologies for production of young fruit trees, taking into account the use of waste biomass for energy and soil amendment related purposes

摘要

The purpose of the experiments and calculations carried out was to determine the cost and energy consumption of the developed modifications of fruit tree production technology. Modifications to the technology of producing one-year apple trees consisted in energy or fertiliser use of the resulting waste biomass. By using waste biomass from production as an organic fertiliser in the technology for producing apple trees it was possible to reduce costs and energy inputs required, while maintaining the effectiveness of production. The lowest total cost of fruit tree production was identified in the case of the proposed, innovative technology involving utilisation of the waste biomass as a natural fertiliser (13 559.5 € ha~(-1)), compared to the highest cost (13 680.3 € ha~(-1)) identified in the case of the previously applied technology. The investigated apple tree production technologies differed in the related energy inputs required for the production process. The least energy-consuming apple tree production technology was the proposed technology, where the cumulative value of energy inputs amounted to 111 253.3 MJha~(-1). As proposed the modification in the fruit tree production technology, where waste biomass from plant nursery is applied as a fertiliser, solves the problems related to biomass disposal and utilisation.
