Granular fertilizers are solid, particulate forms of plant nutrients that are applied directly to the soil. These fertilizers release nutrients slowly over time, providing a steady supply of essential elements like nitrogen (N), phosphorus (P), and potassium (K). Today, granular formulation use is widespread and most pesticides are formulated as a granule in addition to other formulations. Granules also find use in mosquito larviciding, subsoil applications, soil surface applications, baits, and even some foliar applications (e.g. corn borer control).
