macronutrient

 [mak″ro-noo´tre-ent]
an essential nutrient that has a large minimal daily requirement, including proteins, fats, carbohydrates, and water. The term sometimes specifically includes, and sometimes specifically excludes, minerals required in amounts greater than 100 mg daily: calcium, chloride, magnesium, potassium, phosphorus, sodium, and sulfur.

macronutrient

n.
A substance required in relatively large amounts for the normal growth and development of an organism. Macronutrients for animals include fat, carbohydrate, and protein, while for most plants they include chemical elements such as carbon, hydrogen, oxygen, nitrogen, and phosphorus.

macronutrient

A general term for an essential dietary component—protein, essential fats and carbohydrates—which is consumed in large amounts.

Mostly foliar applications of micronutrients are applied, but it can be used for the macro nutrients such as N, P and K, but these nutrients are required by crops in large amounts, therefore foliar applications, two times, fulfill the fertilizer requirements of macro nutrients of crop plants (Abid et al., 2016).
Both hydroponic and soil culture, NPK are the main ingredients of fertilizers used for crop production, the major difference of hydroponics in fertilizer usage is that it contains appropriate amount of all essential micro and macro nutrients that are needed for plant growth and development whereas, in soil culture plants have to get these elements with efforts by expanding their roots to the site of elements consequent upon a lot of energy is needed or those are depleted by multi cropping.
