| dc.description.abstract | Determination of potassium (K) in NPK fertilizers using atomic absorption
spectrophotometry (AAS) at a wavelength of 766,5 nm has been done. From the
analysis it can be seen that the levels of potassium contained in fertilizers NPK is
0,0886 ppm and levels of K2O in the fertilizer NPK 5,33%. | en_US |
