Most of the various types of lawn grasses available to American homeowners are not plants that are native to the US. They need a diet richer in nutrients than is naturally available in most areas, especially on residential properties where the best soil is often removed by the builder prior to construction. The remaining soil lacks organic matter and its resident organisms that generate and convert nutrients into a form that grass can use.

Therefore, American homeowners who want healthy lawns must provide extra doses of the three key nutrients--Nitrogen (N), Phosphorus (P) and Potassium (K)--to the soil so it can support a healthy lawn. Grass uses nitrogen for foliage production, phosphorus for root and seed development and potassium for maintaining general vigor. Frequent applications of nutrients in the form of a balanced granular fertilizer will help compensate for poor soil. Fewer applications are needed to supplement the nutrients that already exist in relatively good soil.

BE SURE TO TAKE NOTE OF THE DIFFERENCES BETWEEN HAVING POOR SOIL AND HAVING GOOD SOIL.
