Kandungan NPK dan Uji Sensoris pada Pupuk Organik Cair Kombinasi Azolla microphylla Dengan Daun Kersen dan Ampas Teh

Abstract

Azolla mycrophylla, Cherry leaves and tea waste are organic materials that have potential as liquid organic fertilizers because they are able to bind nitrogen from the air and contain high potassium. In the manufacture of organic fertilizers, bioactivators such as bamboo shoots are needed to accelerate the fermentation process. The purpose of this study was to determine the content of N, P, K elements and sensory tests on liquid organic fertilizer (POC) combining Azolla mycrophylla with cherry leaves (Muntingia calabura L.) and tea waste. The research method was an experimental method with 2 treatments, namely A1 (a combination of Azolla mycrophylla and Kersen leaves) and A2 (Azolla mycrophylla and tea waste). The results showed that the highest nitrogen, phosphorus and potassium content was obtained in treatment A2, namely N (1.37%), P (0.14%) and K (0.35%) and sensory observations for both treatments met the SNI for organic fertilizer. liquid (2004) and Permentan (2011) with a brown color, pungent aroma like tape, and a pH ranging from 4-5. It can be concluded that there are differences in the NPK and sensory content of the fertilizers found in this liquid organic fertilizer.
