Detailed explanation-1: -Plant roots absorb mineral salts including nitrates needed for healthy growth. For healthy growth plants need mineral ions including:-Nitrate for producing amino acids which are then used to form proteins.-Magnesium which is needed for chlorophyll production.

Detailed explanation-2: -Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur.

Detailed explanation-3: -Nitrogen (N) affects all levels of plant function from metabolism to resource allocation, growth, and development and Magnesium (Mg) is a macronutrient that is necessary to both plant growth and health.

Detailed explanation-4: -Nitrate serves plants as a nutrient and is an important growth factor. It is absorbed from the soil through the roots and helps build organic compounds such as proteins and nucleic acids.
