Lawn fertilizer with natural long-lasting effects from horn meal. This lawn fertilizer is a high-quality organic-mineral complete fertilizer for comprehensive fertilization and simultaneous soil improvement. It is ideally suited for ornamental lawns, play and sports fields, children's playgrounds, and lounging areas. It fertilizes quickly and lasts long, creating lush green, durable lawns and preventing moss formation. It increases the resilience of the grasses. Due to the high proportion of nutrients of organic origin, which supply the grasses over several months, this fertilizer is particularly suitable for improving poorly nourished lawns. Mineral nutrients provide a rapid, but not overly strong immediate effect of nitrogen. With the coordinated combination of quickly and slowly available forms of nitrogen, this main nutrient is appropriately available even with longer fertilization intervals of over two months. The organic nitrogen does not directly nourish the plant, but rather supports the soil life.
