NPK stands for nitrogen (N), phosphorus (P), and potassium (K), three common macronutrients listed on fertilizer products. The numbers in the formulation show the percentage content ofeach element. Plant needs can differ depending on the commodity, growth phase, and soil conditions. Therefore, the selection of formulations and methods of application need to be adjusted to the agronomic recommendations and instructions on the packaging.
