DRT 16-10-17 N-P-K granules were used for CWT analysis. Definite amount of was weighed and added into the water in beaker. Their total weight containing fertilizer water beaker magnetic stirrer recorded. Simultaneously time launched started to rotate at a rotational frequency approximately 300 min-1 . Also is covered with lid avoid evaporation keep temperature constant (25±0.5) °C control equipment. Each nutrient determination desired analyze solution fertilizer decanted another beaker it important take care any undissolved being carried over. Then refilled again 25°C until receiving previously recorded mass. This procedure repeated more than 75 % nominal quantity soluble nutrients has been leached. Aliquots taken as appropriate order determine concentrations nutrients using standard analytical methods. After that extracted calculated.
