According to the horticulture and crop science extension of Ohio State University, fertilizing is an important part of plant health care. Fertilizing plants helps supplement what the soil is lacking, and it also replenishes nutrients that leave the soil. Plant fertilizers come in several varieties and types. It is important to test the soil to determine what is needed to amend it. Fertilizers can be inorganic or organic; granulated, powdered, solid or liquid; and contain varying amounts of nitrogen, phosphorus and potassium. The ratio listed on the packaging refers to the percentages of each of those three nutrients.
