Abstract:
Utilization of bio-based resources to replace fossil fuels has the potential to make progress because of their variable composition and properties which depend on the systems applied. Reed canary grass (RCG) was investigated in an experiment conducted on an Endocalcari-Epihypogleyic Cambisol. The study was aimed to determine the gross calorific value and ash content of biomass as influenced by different fertilization and in-field leaching systems. The composition of the biomass in per cent weight of silicon (Si) and potassium (K), which are the major components of ash, was established. Gross calorific value was a measure of the energy content of biomass samples expressed in MJ kg-1. The data suggest that fertilization with N90 or digestate from biogas plants and in-field leaching for 1 and 2 weeks substantially increased the calorific value of RCG compared with N0 and in-field leaching. The biomass of grass fertilized with N90 and exposed to in-field leaching contained the lowest concentration of ash, which is a desirable feature for combustion process. Silicon in combination with other elements, especially K, affects the ash melting behaviour in grasses. In this experiment, Si reduction occurred only in one-week leaching and non-leaching systems with mineral and digestate fertilization. Both - fertilization and in-field leaching reduced the concentration of potassium.
