Nitrogen functions as a means for the plant to produce more chlorophyll. This will result in abundant growth and allow for a dark green color. Many NPK lawn fertilizers have a high content of nitrogen in order to help produce lush, green grass.
Phosphorus aids in the initial growth of plants by contributing to root development and healthy flowering. Higher concentrations of phosphorus can be helpful when planting a new garden or sowing a lawn.
Potassium in NPK fertilizer provides an immune boost to plants by protecting them from certain diseases. It also aids in solid root development. Potassium also offers protection against seasonal weather such as extreme cold or drought.
