The difference between a homogeneous NPK fertilizer and a blend
A homogeneous fertilizer is one that has been manufactured in a plant that can mix all the ingredients (nutrients) together before the final granulation or prilling process. This means all the granules or prills in that product have the same nutrient analysis, density, shape and size range. In contrast to homogeneous fertilizer, blended fertilizers will have different colored, shaped and sized particles. Straight fertilizers, as they’re called are blended to make up a particular product analysis.
Blended Fertilizer
Made up of completely separate particles of N, P and K. Often with a large variation in bulk density and particle size.
Homogeneous Fertilizer
Each identical particle contains the correct balance of nitrogen, phosphorus, and potassium.
