What is a fertilizer?


A fertilizer is any material, it can be organic or inorganic, it can be natural or synthetic, which supplies plants with the necessary nutrients needed for plant growth and optimum yield. Organic fertilizers are natural materials of either plant or animal origin, including livestock manure, green manures, crop residues, household waste, compost, and woodland litter. Inorganic (or mineral) fertilizers are fertilizers that are mined from mineral deposits with little processes (e.g., lime, potash, or phosphate rock), or industrially manufactured through chemical processes (e.g., urea). Inorganic fertilizers vary in appearance depending on the process of the manufacturer.
