A Fertilizer consists of one or more plant nutrients and is used to strengthen the available supply of soil nutrients in order to improve soil fertility. Fertilizers aid in the maintenance of required soil conditions for different crops by reinforcing nutrients lost due to harvest or other environmental causes.
Macronutrients (primary and secondary) are used in large quantities and are required for plant health. The primary nutrients include nitrogen (N), phosphorus (P), and potassium (K). The secondary nutrients include calcium (Ca), magnesium (Mg), and sulfur (S).
Micronutrients are used in smaller quantities but are required for survival of the plant and these include iron (Fe), boron (B), copper (Cu), chlorine (Cl), Manganese (Mn), molybdenum (Mo), zinc (Zn), cobalt (Co), and nickel (Ni). Fertilizers enhance the growth of plants by either adding said nutrients or modifying the properties of the soil to make it more suitable for a larger yield.
