The Andersons Core 24-6-12 contains micronutrients and iron for super-deep greening. The 24-6-12 formula is balanced to the ideal 4:1:2 ratio of nitrogen, phosphorus and potassium, making it the perfect all-purpose fertilizer. Unless a soil test shows that you need a nutrient adjustment, the majority of experts and studies say the same thing: apply a 4-1-2 ratio fertilizer for the best results as a regular maintenance application. Core 24-6-12's fine particle size ensures more granules per square foot and more even distribution of nutrients. It is beneficial for all turf types and can be applied at any time during the growing season. Quick and slow-release nitrogen sources provide fast results and continual feeding for up to 6 weeks.
