Summary Introduction

Introduction:

Soil is a rich source of nutrients for plants. Depending on the concentration and the combination of mineral nutrients available in the soil, plant growth occurs. Plants use inorganic minerals for nutrition. For example- sulfur is converted to sulfate; atmospheric nitrogen is fixed by the soil so that roots can take it. There are 2 classes of nutrients, which are required for the growth of the plants: micronutrients and macronutrients.

Micronutrients are needed in a very small amount and often required as the enzyme’s cofactors. The name of some micronutrients is zinc, iron, copper, and manganese.

Macronutrients are needed in large quantities. They are known as the building blocks of the cellular components. Carbon, Oxygen, Hydrogen, Nitrogen, Phosphorus, etc are considered as the macromolecules.
