Understanding the NPK Ratio

What the numbers mean on our fertilizer bags and boxes
Our Blends vs. Our Single Ingredient Fertilizers Explained.

Fertilizers are labeled with numbers that represent the percentage of the three primary macronutrients: 
Nitrogen (N) - Phosphorus (P) - and Potassium (K)
These elements are listed as the NPK ratio. 
For example,
Our All Purpose Mix 4-6-2 is a Blended Fertilizer  comprised of each primary nutrient, (N-P-K)
whereas our Blood Meal 12-0-0 is a Single Ingredient Fertilizer  with a single source of (N) of nitrogen. 
Each nutrient plays specific and complementary roles. 

N = Nitrogen - Energizes vegetative growth,
P = Phosphorus - Produces expansive roots, flowers, fruits and viable seeds.
K = Potassium - (or potash) Promotes resistance to disease and temperature stress. 

Most fertilizers will also contain varying amounts of the secondary macronutrients – calcium, sulfur and magnesium – along with trace elements or micronutrients.
