Abstract

Slow release fertilizer with pesticide (SRFP) has been formulated to provide nutrientenriched with pesticide using all natural compound. Matrix formulation is used with poultry manure(PM) as the nutrient source as well as the solid matrix for incorporating neem leave (Azadirachtaindica a.juss) and gendarussa leave (Justicia gendarussa burm) extract as the active compounds. Inthis study, the release of nutrient i.e. nitrogen by the addition of the two leave extracts during SRFPpreparation has been investigated using sand bed column leaching test. The leachate solution wasanalysed by Kjedahl method to measure total nitrogen amount released. Different volume of the leaveextract was investigated to study the effect of the extract addition on the release of the nitrogen. It isshown that the higher the volume of the leaves extract added during the granulation process, the fasterthe release of the nutrient.
