Plant-based liquid organomineral fertilizer contains 40% organic matter (16% organic carbon), 1.8% total nitrogen, and 4% water-soluble potassium (K2O). Its pH ranges from 4.5 to 6.5. When applied to the soil at the beginning of the growth period through drip, sprinkler, or subsurface irrigation, it provides organic matter, nitrogen, and potassium support to the soil, thereby improving soil fertility. When combined with micronutrient fertilizers, it prevents micronutrients from being bound by lime, strengthens soil structure, enhances water retention capacity, regulates air and water circulation, and strengthens soil against erosion.
