Banana fertilizer npk The potash and phosphate in banana peels is 11.5% and 0.4%. The NPK value for banana skins is 0.6-0.4-11.5. But this is the value for dried banana skins since all of the above values are calculated on a dry weight basis. The NPK of fresh banana peels is 1/5 of that, making an NPK of 0.1-0.1-2.3.
