PURPOSE: A liquid sulfur composite for a fertilizer which has eco-friendly properties because of natural ingredients is provided to promote the growth of crops and to enhance immunity by supplementing sulfur and inorganic salts which are deficient in crops, thereby increasing crop production. CONSTITUTION: A liquid sulfur composite for skin care and a fertilizer contains 5-15 parts by weight of water soluble sulfur, 3-8 parts by weight of water soluble potassium, 1-5 parts by weight of water soluble nitrogen, 0.01-0.1 parts by weight of water soluble phosphorus, 0.5-1.5 parts by weight of boron, and 0.05-0.5 parts by weight of silicic acid. The composite further contains one or more selected among 0.01-0.1 parts by weight of water soluble manganese, 0.01-0.1 parts by weight of water soluble copper, 0.01-0.1 parts by weight of water soluble zinc, 0.01-0.1 parts by weight of water soluble iron, and 0.01-0.1 parts by weight of molybdenum. A method for manufacturing the composite comprises the steps of: putting 100 parts by weight of water, 5-20 parts by weight of sulfur powder, 0.5-2 parts by weight of quick lime powder, 0.5-2 parts by weight of phyllite powder, 0.5-2 parts by weight of phosphate ore powder, and 0.1-1 parts by weight of calcium powder in a container and preparing a liquid mixture (S10); stirring the liquid mixture (S20); maturing the liquid mixture at room temperature for 24-48 hours (S30); and extracting a solution containing nutrients from the liquid mixture (S40).
