The aim is to assess the effectiveness of slow-release fertilizers made from pineapple stump biomass and coal fly ash for improving soil nitrogen and plant growth.
Conducted field trials from 2021-2022 in Lampung, Indonesia.
Formulated fertilizers using varying ratios of pineapple stump compost and coal fly ash.
Applied mineral fertilizers with emulsified polymer coatings at different concentrations.
Monitored soil nitrogen status and plant growth metrics over time.
All slow-release fertilizer treatments improved soil nitrogen levels compared to the control.
The 40% compost formulation with higher coatings showed the best results in soil nitrogen status.
Significant increases in root biomass and leaf development were observed in high-compost formulations.
