Pengaruh penggunaan rempah-rempah terhadap kualitas pupuk organik cair

Abstract

This study aimed to determine the best treatment and the chemical content of liquid organic fertilizer with the addition of spices. The levels treatment were treatment 1 (P1): 1.5 liter cow urin+75 ml molasses+100 ml EM4+50 grams of spices each; treatment 2 (P2): 1.5 liters of cow urin+75 ml molasses+100 ml EM4+75 grams of spices each; treatment 3 (P3): 1.5 liter cow urin+75 ml molasses+100 ml EM4+100 grams of spices each, with 3 replications each. The data obtained were analyzed using descriptive analysis. Parameters observed were pH on day 0 to day 10, C-Organic nutrient content, total N, C/N ratio, P2O5 and K2O. The results of this research P3 was a liquid organic fertilizer with the best quality because it has the lowest C/N ratio. Liquid organic fertilizer from cow urine with the addition of spices has a C-Organic content at P1 2.99%; P2 2.76%; and P3 2.74%, total N at P1 0.17%; P2 0.18%; and P3 1.74%, C/N ratio at P1 18; P2 15; and P3 4, P2O5 at P1 0.04%; P2 0.02%; and P3 0.03%, and K2O at P1 0.77%; P2 0.83%; and P3 0.86%.
