What are the different types of fertilizers?
There are several types of fertilizers. Most common are the general-purpose lawn & garden fertilizers. They may be palletized or granulated, and are usually formulated to address various plant, soil and climate zone requirements. They are sized to be used in a standard drop or cyclone spreader. Individual macronutrients, such as nitrogen, phosphate and potassium, are also available, as are micronutrients, usually in powder or granular form, but they should be used sparingly, and only when recommended as a result of a soil test, or to correct a specific plant or soil deficiency. Most nutrients are also available in liquid form, and can be used as a drench or as an ingredient in foliar sprays. It is a little-known fact that plants feed as efficiently through their leaves as they do through their roots.
