Abstract

Organic fertilizer is one of the important factors needed in organic farming. The need for organic fertilizer increases with the demand for organic food. Seaweed is used as raw material for organic fertilizer because it contains growth hormone, macro and micro nutrients that are complete for plant growth. The addition of molasses was intended to increase Corganic levels which is a standard requirement for organic fertilizer. The study was aimed to evaluate the optimal concentration of molasses and their effects on the chemical characteristics of the organic fertilizer. The observed parameters were moisture, ash, Corganic, N-total, C/N ratio, and potassium content of the organic fertilizer. The results showed that an increase in molasses concentration caused an increase in the moisture content, Corganic content, and C/N ratio in seaweed solid organic fertilizer.
