Fertilization efficiency of wood ash pellets amended by gypsum and superphosphate in the ryegrass growth
Application of biomass ash to soil can save mineral nutrients due to its relatively high contents of Ca, K, and P. The study assessed the effect of powdered ash and pellets made from wood fly ash (WFA), combined moreover with additives rich in S (flue gas desulfurization gypsum - FGDG) and P (single...

| Summary: | Application of biomass ash to soil can save mineral nutrients due to its relatively high contents of Ca, K, and P. The study assessed the effect of powdered ash and pellets made from wood fly ash (WFA), combined moreover with additives rich in S (flue gas desulfurization gypsum - FGDG) and P (single superphosphate - SP) on the yield and uptake of nutrients (Ca, K, P, and S) by ryegrass (Lolium perenne L.), the accumulation of nutrients in plant biomass at individual four cuttings, and the available nutrients amount in the acidic loamy soil after the last harvest. Plants grown in pots enriched by wood ash showed significantly higher yield and nutrient uptake than in the unamended treatments. The uptake of nutrients by plants, content of nutrients in plants and in soil was substantially positively influenced by both components added to the wood ash, especially by FGD gypsum. The combination of wood ash with additives proved to be effective. The soil enrichment by WFA + SP + FGDG increased the availability of SP-contained P and available P content in soil even after harvest. |
