Types of nutrients
There are two major types of nutrients that plants seek for their growth, such as macronutrients and micronutrients.
Macronutrients are the nutrients required by plants in large quantities.
Example:
Macronutrients include  nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), sulfur (S), magnesium (Mg), carbon (C), oxygen (O), hydrogen (H).
Micronutrients are the nutrients required by plants in small quantities.
Example:
Iron (Fe), boron (B), chlorine (Cl), manganese (Mn), zinc (Zn), copper (Cu), molybdenum (Mo), nickel (Ni)

Important!
The quality of plants depends upon the quality of the oil. It is necessary to take care of the quality of the soil to produce a good yield from plants. Therefore, farmers add fertilizers to the soil. These fertilizers enrich the soil with additional nutrients like sodium, potassium, phosphorous, nitrogen that is in turn absorbed by the plants and is used to synthesize other components of food such as proteins and fats.
