Penentuan Kadar Nitrogen, Fosfor dan Kalium pada Pupuk NPK.

Abstract

Determination of Nitrogen Level, Phosphor and Potassium has been done of NPK Fertilizer. The method performed on the determination of nitrogen content was titrimetric method, determination levels of phosphorus was by spectrophotometric method, while the determination of potassium levels was by using AAS method. From the analysis results obtained that Nitrogen, Phosphor and Pottassium level in NPK fertilizers were 11,45%, 6,20% and 9,92%, respectively. The obtained results show that level of nitrogen, phosphor and potassium were same as SNI (Indonesia National Standar).
