Nitrogen (N)
It makes up 78% of the atmosphere and is essential for plant growth as it is the basis for plant cell construction and chlorophyll. It is considered the basic element for productive agriculture and for this reason it usually represents the highest percentage in NPK fertilizers.
Phosphorus (P)
The second component of NPK fertilizers and is essential for root development, photosynthesis, energy transport, and also in flowering and fruiting. Phosphorus deficiencies lead to stunted plant growth and increased vulnerability to insects and diseases.
Potassium (K)
The third element in the NPK triad. Although it does not serve to build plant tissue, it is essential for regulating plant metabolism. Potassium deficiencies lead to leaf necrosis, stunted growth and plant weakness.
