is a common term that describes a group of elements, that grass plants require, in order to stimulate growth. Besides these naturally occurring ingredients in the soil, there are also other trace elements crucial for proper growth and strong root development. The important nutrients that are needed for optimal growth and appearance, are quickly depleted, by fast growing grass. In time, these deficiencies begin showing results in, thinning lawns of poor color, an increase in various types of weeds, insect infestations, and even lawn diseases. Remember, just as you can’t go long without eating, a lawn can’t thrive without proper fertilization.
