There are three main types of fertilizers: organic, water-soluble and synthetic. Organic fertilizers are made from natural ingredients and have a slow release, meaning that the materials in these fertilizers must be broken down by soil microorganisms for the gradual release of nitrogen and other elements.
Most fertilizer is a blend of three main chemicals that many plants need--nitrogen, phosphorus and potassium. These nutrients are provided in air and water. However, due to weather and the rate of growth of the lawn, these nutrients can become depleted.
