Feb 15,2021·1.Introduction.Phosphorus (P) is one of the most important fertilizers in agriculture system.However,the majority of commercial P fertilizers such as monoammonium phosphate (MAP) and triple superphosphate (TSP) were readily fixed by irreversible adsorption or precipitation especially with acid weathered and calcareous soils,resulting in low bioavailability for crops ,,.Influence of Feedstock on the Release of Potassium,Sodium The objective of this work was to investigate the influence of feedstock on the release of trace elements during gasification.Therefore,different types of woody biomass and biomass residues (shells) were thermochemically converted in an atmospheric flow channel reactor furnace at different temperatures (900,1200,and 1400 °C) under gasification-like conditions.For the determination of the Influence of Phosphorus on Alkali Distribution during The influence of phosphorus on the alkali distribution in fluidized (quartz) bed combustion using two different typical biomasses (logging residues and wheat straw) was studied.Phosphoric acid (H3PO4) was used as an additive.The produced ash fractions were analyzed for morphology and elemental composition by scanning electron microscopy-energy-dispersive spectroscopy (SEM-EDS),and
