Abstract: A granule fertilizer composition with dethatching agent. The fertilizer composition includes natural potassium, various micronutrients, humic acid and composted humus. Ingredients of the composition may include humic acid, nitrogen, sulfur, potash, iron, manganese, magnesium, and/or inert ingredients. In an embodiment, each ingredient is polymer-coated, depending on the needs of the user. The current invention also enables a method of manufacturing a fertilizer composition, along with methods of fertilizing, dethatching and irrigating a finite area of turf using a fertilizer composition. The novel fertilizer composition is environmentally friendly, can be utilized year round effectively for warm and cool turf needs, increases water retention (i.e., reduces amount of irrigation needed), aids in micronutrient uptake, provides soil biology, and prevents staining on concrete.
