The macronutrients are taken-up in larger quantities; hydrogen, oxygen, nitrogen and carbon contribute to over 95% of a plant's entire biomass on a dry matter weight basis. Micronutrients are present in plant tissue in quantities measured in parts per million, ranging from 0.1 [ 3 ] to 200 ppm, or less than 0.02% dry weight.
As many know, healthy, nutrient-rich soil supports a productive vegetable garden. Nitrogen (N), phosphorus (P), and potassium (K) are the key macronutrients required by plants for their growth.
Macronutrients are defined as a class of chemical compounds which humans consume in relatively large quantities compared to vitamins and minerals which provide humans with energy. Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per gram) proteins and carbohydrates 17 kJ/g (4 kcal/g). [2]
All macronutrients except water are required by the body for energy, however, this is not their sole physiological function. The energy provided by macronutrients in food is measured in kilocalories, usually called Calories, where 1 Calorie is the amount of energy required to raise 1 kilogram of water by 1 degree Celsius.

Variety is key Because plants generally contain less protein than meat, Spector wrote that he incorporates "a good mix" of plant-based protein sources into his diet throughout the day.
Protein is one of the body’s three macronutrients: those your body needs in the largest amounts in order to perform. ... a varied diet is the key. “Some plant proteins are lower in certain ...
In many countries, regulations require that food product labels display information about the amount of any macronutrients and micronutrients present in the food in significant quantities. Nutrients in larger quantities than the body needs may have harmful effects. [1]
The macro-nutrients are consumed in larger quantities and are present in plant tissue in quantities from 0.15% to 6.0% on a dry matter (DM) (0% moisture) basis. Plants are made up of four main elements: hydrogen, oxygen, carbon, and nitrogen. Carbon, hydrogen, and oxygen are widely available respectively in carbon dioxide and in water.
