- Optimization of the biodegradable wastes management is one of the main goals of the activities taken up in the European Union. The aim of the present paper is to define the possibilities of supporting the process of golden rod yield (Solidago canadensis L.) by using different mineral-organic fertilizers, in a form of granulated substances, produced from extracted coffee wastes (CSG) as well as from ash which is the result of woody biomass combustion. Golden rod, as a potential energetic plant, is very easy to grow because it covers the grounds which are not utilized agriculturally or the ones localised in the close neighbourhood of industrial areas. For certain experimental purposes, a field experiment was conducted. Six experimental plots constituted its basis, two experimental fertilizers based on the extracted coffee wastes (in the amount of 100g/m2), ash from the process of thermal biomass transition and two commercial fertilizers were applied. After 160 days of the experiment, the golden rod harvest was submitted to quantitative-qualitative analysis. An analysis of basic soil parameters (pH, EC, TOC) was also carried out and the content of significant elements, as far as fertilizers are concerned, N, P, K, Ca, Mg was analysed too. As a result of the conducted experiment, the yield rise was observed, both in the case of the plants fed with commercial fertilizers as well as the ones cultivated on the basis of the extracted wastes. Using fertilizers does not only allow for management of the wastes produced in farm areas but also enables to increase the achieved amount of golden rod crops as well as to boost energy that is sourced in the process of biomass used for energetic purposes.
