Like people, plants need a multitude of nutrients to thrive. These are categorized into micronutrients, such as zinc and iron; secondary macronutrients; such as calcium and magnesium; and three primary macronutrients: nitrogen (N), phosphorus (P), and potassium (K). Mineral fertilizers provide higher and more plant accessible nutrients, while organic minerals importantly also provide carbon, which contributes to healthy soils. While efforts to reduce nutrient losses to the environment must be continued and stepped up, it bears emphasizing that fertilizers play a crucial role in agricultural productivity.
