What is N-P-K?

  • N is for Nitrogen

    • Nitrogen is an essential nutrient for plant growth, development, and reproduction.

    • Despite nitrogen being one of the most abundant elements on earth, nitrogen deficiency is probably the most common nutritional problem affecting plants worldwide – nitrogen from the atmosphere and earth's crust is not directly available to plants. 

    • Nitrogen essential for plants.

  • P is for Phosphorus

    • Phosphorus in and for plants is very important.  Unlike other nutrients, it helps plants promote cell division and convert other nutrients into usable building blocks which aid a plant through its growth cycles.

    • Phosphorus is one of the main three nutrients most commonly found in fertilizers and is the “P” in the N, P, and K balance that is presented on most of or nutrients and fertilizers.

    • Phosphorus is essential to a plant’s growth.

  • K is for Potassium

    • Potassium or the element abbreviation (K) is for a plant’s overall health and vigor.

    • Adequate levels of Potassium ensure the overall health and longevity of plants.

    • Plants will show they are Potassium deficient with browning/darkened edges (almost look burnt) on their leaves and will often produce very few blooms/fruit.

    • There is no level at which K becomes toxic to plants, but excessive K can block the absorption of the other two nutrients.
