Lawns are an important component of many home landscapes. Good cultural practices are necessary to achieve a healthy, attractive lawn. One important cultural practice is fertilization. The benefits of a well-maintained lawn fertilization program are good turf color, quality and density. There are 14 elements which are often referred to as mineral nutrient elements and are generally obtaining in the soil via root extraction.

However the demands for nitrogen, phosphorus, and potassium often exceed the supply in the soil. Thus, it becomes necessary to add these elements through fertilization.
