Pengaruh Penambahan Effective Microorganisme-4 (Em4) Pada Kandungan Unsur Hara Makro Pupuk Organik Cair (Poc) Dari Rebung Bambu

Abstract

This study aimed to determine the value of macronutrient content in liquid organic fertilizer from bamboo shoots and to see the effect of adding EM4 on the value of the nutrient content. The volume of EM4 used varied by 100 ml, 150 ml, 200 ml, 250 ml and 300 ml. The fermentation process took place for 2 weeks and then tested for macronutrient content, including Organic Carbon content, analysis of nitrogen content, phosphorus, potassium, and pH test. For the analysis data, it was found that the best recommendation for adding EM4 was 250 ml with a nutrient content of N, P, K of 2.03%. These results conform to the minimum thecnical requirements for liquid organic fertilizer of 2% to 6%.
