Question

What are macronutrients and micronutrients in plants?

Answer 1

In relatively large amounts, the soil supplies nitrogen, phosphorus,potassium, calcium, magnesium, and sulfur; these are often called the macronutrients. In relatively small amounts, the soil supplies iron,manganese, boron, molybdenum, copper, zinc, chlorine, and cobalt, the so-called micronutrients.

Answer 2

Macronutrients and Micronutrients :

Macronutrients are those essential elements which are present in plants in easily detectable quantity is more than 1 PPM of plant body. macronutrients take part in synthesis of organic molecules and development of osmotic potential.

Six macronutrients are :- nitrogen , Phosphorus, potassium , calcium, magnesium and sulphur. While micronutrients are those essential elements which are present in plants in small quantities, less than 1 PPM or 1 mg per gram of dry matter. 7 micronutrients are :- iron, MN, boron, zinc, copper, molybdenum and chlorine.
