The effect of functional bacterial consortium on nutrient content of liquid organic

Abstract Bacterial compatibility testing is very important to determine which bacteria will be consorted as bio activators when making liquid organic fertilizer. Bacteria that are inoculated into the manufacture of fertilizers must have a cooperative and synergistic relationship with fellow efficient in their role activators. To obtain this potential, test against bacterial isolates needs carried out so made effective. The research purposes compatible properties functional impact on fertilizer’s nutritional content. study was at Plant Protection Laboratory Greenhouse Payakumbuh State Agricultural Polytechnic, West Sumatra from July September 2022. method began rejuvenation dry Pseudomonas aeruginosa, Bacillus subtilis, cereus , thuringiensis . Followed by using double culturing method, total 20 treatments three replications. consortium results P. aeruginosa genera showed all were indicated absence halo inhibition zone index value between 0.67-1 could combined activator. best P 2 O 5 K O, Ca nutrient content found formula fertilizer bone meal additives.
