Abstract: Liquid organic fertilizer is increasingly applied in crop production to optimize the use of solid organic fertilizer. Green biomass is one of composing material for the production of liquid organic fertilizer, since the nutrient contents in plant tissue determines the quality of liquid organic fertilizer. The first experiment was the identification of the nutritional content of moringa and seaweed leaves, included nitrogen, phosphorus, potassium, magnesium, magnesium calcium, organic carbon, cellulose and lignin. The second experiment was the effect amendment of moringa and seaweed green biomass on nutrient properties of liquid organic fertilizer and was conducted in a completely randomized design. The treatment was consisted of (1) moringa leaves of flowering twigs, (2) moringa leaves of unflowering twigs, and (3) seaweed. The first experiment revealed that the highest nitrogen, phosphorus, and magnesium contents were found in unflowering moringa leaves, while the highest potassium, calcium and cellulose were found in seaweeds. In addition, flowering moringa leaves had the highest lignin content among evaluated plant leaves. The second experiment found that the highest of nitrogen content was found in LOF produced by using seaweeds, followed by those in using unflowering moringa leaves and flowering moringa leaves. The highest of calcium, magnesium and organic carbon were recorded in LOF produced by using unflowering moringa leaves followed by followed by those in using flowering moringa leaves and seaweeds. In addition, the highest pH, phoshorus, and potassium were found in LOF produced by using flowering moringa leaves.
