Prolonged action fertilizer encapsulated by CMC/humic acid

Abstract The present study focuses on the evaluation of a novel prolonged action fertilizer that has been encapsulated by combination carboxymethyl cellulose (CMC) and humic acid (HA). aim this research was to investigate release essential plant nutrients: phosphorus, nitrogen, potassium. This investigated material composition nutrient properties CMC HA. these nutrients determined quantifying their concentrations over time using various analytical techniques, such as photometric, titrimetric, flame photometric methods. results revealed CMC/HA matrix effectively controlled release, with extended-release durations observed under acidic (pH 5.0) neutral 7.0) conditions compared alkaline environments 8.5). indicates is well suited for variety soil pH conditions, particularly in soils. information could have important implications development more sustainable environmentally friendly technologies.
