Macronutrients and Micronutrients

The concentrations of essential elements in plants may exceed the minimum concentration required for critical concentration, growth, and may vary from species to species. Nevertheless, the following table shows the general requirements of the plant.

Regardless of mg / kg (= ppm, parts per million) or percent (%), concentrations are always based on dry weight, not fresh weight. Living weight includes the weight of dry matter and the weight of water in the tissue. As the percentage of water can vary widely, by convention all elemental concentrations are based on dry matter weight.

Others divide the boundary between what is required for large amounts of nutrients, macronutrients, and small amounts of micronutrients. This division does not mean that one nutrient is more important than the other, except that they require different amounts and concentrations. In the table above, dividing lines are usually drawn between S and Cl.

The use of the prefix "micro" from terms such as "microscope" is well understood. The term "macro" is not very common, but it refers to an object with a slightly larger size. The intermediate size is sometimes indicated by "meso". For example, soil animals (animal lives) are divided into large animals (animals, rats, etc.), medium size animals (such as insects, and miniature animals such as nematodes).

So, what is a nutrient? What is the difference between macronutrients and micronutrients? Many nutrients are basically a way of classifying calories in food into one of three groups, carbohydrates, proteins, and fats. "Macro" means superb, so the official definition of macro nutrients covers a relatively large amount of every substance that human beings need. On the other hand, "trace amount" means very small. In other words, there is much less micronutrients such as vitamins and minerals.

In the nutrition science, there are two major categories necessary for the body to work. Macro nutrients and micronutrients. Many nutrients such as protein, carbohydrate, fat are necessary for the body. Micronutrients are various substances that smooth the wheels. Vitamins, minerals and other things that make up the reason to say that mama always eats green vegetables. You need a relatively small amount of micronutrients, but you only need a little bit, and many will go wrong when you do not have them. Scurvy pirates are a famous example: seafarers can not get fresh fruit (like modern Alaska), they are often devoid of vitamin C This is sometimes fatal, It leads to a very special state. Well, if I do not eat broccoli at lunch today, I do not say that I will eat at a hospital, but the lack of micronutrients will have a negative impact on my health.

All food we eat contains two main types of nutrients: micronutrients and macronutrients. Both are very important dietary ingredients, macronutrients and micronutrients are an important element of eating nutrition, dieting and supporting overall health. So, what is a nutrient? What is the difference between macronutrients and micronutrients? Many nutrients are basically a way of classifying calories in food into one of three groups, carbohydrates, proteins, and fats. "Macro" means superb, so the official definition of macro nutrients covers a relatively large amount of every substance that human beings need. On the other hand, "trace amount" means very small.
