Chemical fertilizers are synthetic substances that provide the necessary nutrients for healthy plant growth and development. Chemical fertilizers combine synthetic forms of the primary macronutrients for plants such as nitrogen, phosphorus and potassium, as well as a variety of micronutrients and additives. Synthetically developed fertilizers provide the benefit of having more nutrients per pound than organic fertilizers, thus reducing costs. Chemical fertilizers have many uses for the average gardener and home-grower, as well as for commercial use.
Plant and vegetable growers use chemical-based fertilizers for healthy plant growth. The nitrogen in fertilizer promotes cell division and leafy vegetation, phosphorus helps plants with photosynthesis and respiration and potassium helps plants absorb other nutrients. Chemical fertilizers contain a higher concentration of macro-and-micronutrients than organic fertilizers, which allows growers to spread less of a concentration for the same results. Depending on brand, chemical-based fertilizers provide varying levels of additives, which help grow plants faster and stronger. However, according to Pennsylvania State University, over-fertilization, a common problem with chemical-based fertilizers, can cause poor growth and even plant death. University or private labs can test soil samples to determine the recommended amount of fertilizer to apply for specific garden plants.
