Fertilizer is food for plants. Plants, like any other living thing, need a variety of nutrients to grow and thrive. Humans and animals get their nutrients through the different foods they eat, plants obtain their nutrients through the soil. However, some soils don’t meet the nutrient requirements necessary for plants to grow, or the nutrients are in forms that make it difficult for the plants to uptake. This is where fertilizer comes in.
Fertilizer is used as a nutrient supplement for plants. The nutrients found in fertilizers are primarily nitrogen, phosphorus, and potassium and are in a form that is easily absorbed by the plant’s roots.
